I try to communicate with a PDA, HP iPaq, through the serialport. The baud rate is the number of signalling elements transmitted per second. Only make an application to the lender for the loan that you intend to take. So my McMurdo AIS is to set to output at 4800 which works fine given the relatively traffic free West Coast of Scotland. How to calculate Bandwidth from given transmission rate in bits per second? How to convert bit rates to frequency? I need to calculate rate, based on the formula bellow:. Baud rate is defined as the number of symbols sent or received per second. In normal operations, the "baud rate" should therefore always be zero, thus indicating that signalling is happening at a constant speed. Borrowers pay a premium for predictability – knowing exactly what their interest rate and mortgage payment will be for a five-year period. For example, at 115k baud, your cable should not be much longer than 2,500 feet. Some of the PC CAN interfaces allow direct modification of the SJA1000 Baud Rate Timing Register (BTR) to allow use with non-standard bus speeds. As the baud rate increases the serial cable connecting your A/V equipment and its controlling system must decrease. Rate of Data Transfer. 40: In _____ encoding, the duration of the bit is divided into two halves. The Bit Rate Output (Z) drives one standard TTL load or four low power Schottky loads over the full temperature range. GM's 160 baud ALDL on a Serial Port. On reset D7 (CO select) is reset to 0. Baud rate and bit rate are NOT the same Baud rate (Bd) is the number of line state changes possible per second Bit rate (bps) is the number of bits transmitted per second The hardware we are using has two line states (high/low) Two line states can be represented with one bit In our hardware, 1 baud = 1 bit Nick Earnhart Baud. Till now I am able to use up to 115200 baud rate in this baud rate. For async serial connection, the baud rate only specifies the bit rate for the bits in the character frame. 1 Attributes of the MSP430 UART The following is a short overview of the USART. - Compression Techniques Forum.

How to create a 3D Terrain with Google Maps and height maps in Photoshop - 3D Map Generator Terrain - Duration: 20:32. ) MCAN Module: IPT = 3 TQ if 3 samples per bit are selected. Bit rate is simply the number of bits (i. T = 1/bit rate For example, a 1200 bit per second baseband MSK data signal could be composed of 1200 Hz and 1800 Hz frequencies for a logical one and zero respectively (see Figure 1). it all depends on the CAN network length. PACTOR is a synchronous transmission system with a packet duration of 0. The Standard baud rates Comes from the sixties. For example, to send one byte of data at 9600 baud rate, each bit is sent at 108 µsec delay. USART Baud Rate Generator (BRG) Baud Rate Generator provides the required clock for the data transmission and reception. The edge trigger detects whether a potential of a transmitted signal is raising or falling. 80 = TD1, bitwise as 10000000, bits 8 to 5 state whether TA2, for bit 5, TB2, for bit 6, TC2 for bit 7, TD2 for bit 8 are present or absent, here means TD2 exists. The Baud rate table (Table 34-4. Nowadays, however, there has to be a distinction made between the two since symbols can contain more than one bit. The available rates and the main clock rate usually decide the available TQ-per-bit. This value is then used to calculate the UART divisor values. There is no analytic formula for determining the optimum bit time in advance, so the calculator tries all of them. Result will be displayed. SWITCH SELECTABLE BIT RATE GENERATOR CON-FIGURATION PROVIDING FIVE BIT. The time each bit is present for (the bit time) is the reciprocal of the baud rate - baud rate = 1 / bit time bit time = 1 / baud rate Asynchronous Serial Timing A transmitting device should send its data at a specific baud rate with the correct bit time but that the bit timing actually used may sometimes be too short or too long. The speeds are optimistic because the actual inferface will be slowed down by overhead (ex: requests for the information, syncs, ), more than one transfer at a time, and the interface not performing at the standard speed. second, with a unit of bit/sec, commonly known as baud rate or bit rate. If you paster the serial log in the log parser, you can see the library finishes setup and then enters the setup() function:. log 2 M gives us the number of bits that can be represented by a single symbol. Change the baud rate to 115200; Select ‘Serial’ on the menu on the left, then click ‘Open’ Mac OS. Baud rate or Symbol rate is the number of signal elements per second. For example: A non-standard Baud rate of 490000 Baud is required. Think of baud rate as the switching speed, and bps as the switching speed times the amount of information present at each switch. So, because you always send bytes of 8 bits each, and 2 aditionally bits (start and stop), the transfer rate of data is 8+2=10, or 1/10 from baudrate. 6000 bps, QPSK d. The goal of this article is to teach you how to use price to earnings ratios (P/E ratios). Baud Value Decoder. Dear Sir,I would like to calculate the speed of tranmission of data on above three Bus system. FORUM THREADS. Based on it we determine bit rate according to following formula BRP = FREQUENCY / (2 * T Q * BITRATE). I started work with UART of lPC1788,in that I did the following settings for PCLK as 12MHZ and baud rate as 115200 but while i am simulating this code the baud rate is not assigned as 115200 or approx. In other words, symbol rate given in baud equals data rate given in bits per second. The major problem is that 115200 is not a clean baud rate if you use a 16mhz quartz, it is faked by a close approximation frequency (IIRC 5-7% change), that creates bit-errors. The speeds shown by download time calculator is purely theoretical. Hence baud rate is one half of bit rate. The hardware selection of the oscillator, and the software configuration of the BRP and number of TQ per bit time set the data rate. X and J2602. Ill post it for whoever needs it in the future. For most use cases the UART can be easily configured by choosing the BAUD rate, parity, number of data bits and number of start bits. We'll show how you can use Rai Way S. Repay IN FULL or it's 28. My measured time to send the 8 bit. How fast is 60 WPM in terms of baud?. Typical baud rates for modems started out at 110 baud in the 1970s and increased quickly through 300, 1200, 9600, 192000 and 56000 baud in the 90’s. Unless you are doing some fancy coding the basic symbol is going to be the bit and the Baud rate will be the same as the bit rate. The wikipedia entry on baud covers your question in some detail: "Digital data modem manufacturers commonly define the baud as the modulation rate of data transmission and express it as bits per second. This is the time quantum from ISO 11898-1, 12. its for work i have a meter that collects data, its set to 19200, i have installed the software and its set to 19200, my problem is the cable. The MB Time Calculator can be used to compute CAN bit timing parameters for Microchip Technology MCP2510, MCP2515, and PIC18F CAN controllers, with both legacy and ECAN supported. The major problem is that 115200 is not a clean baud rate if you use a 16mhz quartz, it is faked by a close approximation frequency (IIRC 5-7% change), that creates bit-errors. In ASK the baud rate is the same as the bandwidth, which means the baud rate is 4000. RxD (Receive Data) The RxD input line is used to transfer serial N RZ data into the ACIA from the modem, LSB first. 26us so by using 2 bit periods you will increase the time to 16. Use our estimator to find labor costs. If you are not sure, use 115200 and type the command AT. We'll show how you can use Rai Way S. This damping must occur before the bit is sampled or within half a bit time. With three bits. The application contains communication configuration, language and data saving path. second, with a unit of bit/sec, commonly known as baud rate or bit rate. The number of bits per character will effect the number of character per second that you transmit but has no bearing on the actual Baud rate. Data Size: 16-bit Display Format: Hexadecimal Related Section: 9. The Baud rate of a communications system is the symbol rate of a system or the maximal number of symbols that can be transmitted per second. The PIC32 family's bit rate prescaler is only programmable between 1 to 64. In my code, F_CPU is the clock rate of the…. The transmission mode for MFSKpic is similar to FAX. Bit Rate vs. Baud rate is the number of signal units per second. 1 Answer to Calculate the bit rate for the given baud rate and type of modulation. How to Calculate Data Transfer Rate. usbmodem1422 115200, replacing /dev/cu. Programming steps. Baud (from Jean-Maurice-Emile Baudot, the French inventor of the. This is similar to bit rate except that each symbol usually consists of more than 1 bit. It is important to note that bit rate and baud rate may or may not be the same depending upon the modulation techniques used. First up, we have the baud rate we’re going to communicate at. The maximum recommended data rate in the RS-485 standard from 1998 is 10Mbps, which can be achieved at a maximum cable length of 40ft (12m). Baud rate or Symbol rate is the number of signal elements per second. It is exactly what it sounds like. An explanation of bit rate and baud rate and related bandwidth considerations for wired and wireless data communications. In that case, try the Amex Platinum Cashback card (eligibility calculator / apply*). Based on it we determine bit rate according to following formula BRP = FREQUENCY / (2 * T Q * BITRATE). Bit rate or data rate is the number of bits that can be transmitted on the link per second. Administrátor těchto stránek se zříká jakékoli odpovědnosti za případné ublížení na zdraví či poškození nebo zničení majetku v důsledku elektrického proudu, chybnosti schémat nebo i teoretické výuky. • The rate at which data can be sent depends on – the number of signal levels – the amount of time the system remains at a given level before moving to the next. There are many commercial software for BW, Symbol rate and bit rate calculation for TV signal transmission. The baud rate is the s. When the change baud rate command (0x11) is received, the last valid baud rate value received becomes the new baud rate. 1000 baud, FSK b. Bit rate is simply the number of bits (i. The idle time is required for turaround procedures and settling, which allows for a maximum distance of about 20,000 km as in AMTOR. for 9600 baud rate load 0xFD. This File Transfer Time Calculator is used to determine the approximate time that a file would take to transfer over a particular interface. The RS-232 protocol controls the baud rate. If there is no integer ratio from the main clock to the bit-time of the desired baud rate, the MCU will not be able to exactly produce the desired rate. Bandwidth vs Data Rate When talking about network connections, sometimes, the two terms ‘bandwidth’ and ‘data rate’ are used with the same meaning of data transfer rate (or bit rate). That leads to ‘strange’ system clock frequencies like 4. Baud Rate (CANBUS) The Baud-rate on a CANBUS device refers to the rate (speed) at which data is transmitted on the network. What’s The Difference Between Bit Rate And Baud Rate? (. You can calculate the maximum transmission rate in characters per second for a given communication setting by dividing the baud rate by the bits per character frame. I try to communicate with a PDA, HP iPaq, through the serialport. Baud rate is less than or equal to the bit rate. 166666666666 microseconds. From these four choices an. RS232 data format- (baud rate-data bits-parity-stop bits) This is the way the data format is typically specified. Find the right high-yield. " Please note that this is related to the gross bit rate. Thus, the bit time equals the time of an FSK signaling element, and the bit rate equals the baud. Calculate the baud rate for given bit rate and type of modulation a) 2000 bps, 4-PSK b) 4000 bps, 8-PSK c) 4000 bps, 4-QAM Assignment 6. The assumptions. Free TCP/IP Network Calculators. The "modulation" value allows one to get a rough average bit rate, but individual bit times may be long or short. bit: a unit of information baud: a unit of signaling speed Bit rate (or data rate): b Number of bits transmitted per second Baud rate (or symbol rate): s number of symbols transmitted per second General formula: b = s x n where b = Data Rate (bits/second) s = Symbol Rate (symbols/sec. The rate at which information is transferred over the RS-232 communication channel is known as baud rate. Best Answer: Symbol rate (also known as baud or modulation rate). The baud rate is the reciprocal of the time to send 1 bit. The TQ time can be configured to different times. For example 9600 8 N 1 uses 10 bits per word (1 start bit, 8 data bits, and 1 stop bit). g 9600 baud rate, than the total time could be calculated as under. The typical baud‐rate is 9600 bits per second (Baud, Bd), and the time Tb equals 104. Enter your external clock rate and desired baud rate, then click on the Calculate button. ) n = Number of bits per symbol. Setting this bit will reduce the divisor of the baud rate divider from 16 to 8, effectively doubling the transfer rate for asynchronous communication. Bit Rate [Baud Rate * Signal Unit]: 4000 bps (bits per second) Bit rate and Baud rate, these two terms are often used in data communication. Emile Baudot invented 5 bit telegraphic code. Online converter for units of data transfer rate. In addition to TXD and RXD connections, UART devices may also contain Clear to Send (CTS) and Request to Send (RTS). It is not possible to have split (different baud rate for send and receive) rates. Every time you record, export, or watch a video, bit rate has a lot to do with the quality. NI-VISA returns a success if the driver supports the desired baud rate. A combination of eight samplers and an integrator recover four data bits in each clock cycle. A symbol can have more than 2 states so the baud rate can be less than the bit rate. It is important to note that bit rate and baud rate may or may not be the same depending upon the modulation techniques used. For example, at 9600 bps the bit time is 1/9600 = 104 microseconds. The maximum line length is 1Km, 40 meters at 1Mbps. The baud rate prescaler (BRP) for the oscillator or internal clock sets the time quantum (TQ), and the bit time is a multiple of TQ. Each serial port can be configured for the RS232 or RS485 protocol, and runs at standard baud rates up to 115,200 bits per second. For data quantity, you may choose between binary (e. Additionally, the sender and the receiver needs to have the processing capability to encode and decode symbols at the baud rate. At 19200, bit time is 52. Bit[4 to 7]-MULVAL: This defines Prescale Multiplier value. 0 BLE protocol. In my code, F_CPU is the clock rate of the…. Result will be displayed. The bit rate is the number of bits transmitted per second, whereas, the baud rate is the number of signal units transmitted per second and one signal unit is able to represent one or more bits. speed is the baud rate. FORUM THREADS. The baud rate specifies the frequency at which bits are sent. In other words, symbol rate given in baud equals data rate given in bits per second. Bit Rate [Baud Rate * Signal Unit]: 4000 bps (bits per second) Bit rate and Baud rate, these two terms are often used in data communication. Other baud rates are also common: 19200 Bd, 38400 Bd, 57600 Bd,. CAN Best & Worst Case Calculator. What is the relationship between frequency and bit rates? then every time non-return to zero, inverted changes its logic level, MLT-3 must do the same. The RS-232 protocol controls the baud rate. The wii mote works at a baud rate of 19200. In fast AVRs (megas) it is a 16-bit register that allows low baud rates at high CPU speeds. STC MCU Limited. The most common and standardized value is 9600. 1F = TD2, here means TA3 exists. When a Baud rate is passed to the driver where the exact divisor required is not achievable the closest possible Baud rate divisor will be used as long as that divisor gives a Baud rate which is within +/- 3% of the Baud rate originally set. 29 specifies 4 bits per symbol, at a symbol rate of 2,400 baud, giving an effective bit rate of 9,600 bits per second. A more realistic bound would be significantly less than 1/2 that, with room to grow downward to an almost infinite extent. Some of these cookies are essential to the operation of the site, while others help to improve your experience by providing insights into how the site is being used. Baud (from Jean-Maurice-Emile Baudot, the French inventor of the. So, the Bit rate = 5000 x 3 = 15,000 bps. For me it is more appropriate to talk about bit rate (or bitrate) rather than baud rate. Emile Baudot invented 5 bit telegraphic code. Both the transmitter and receiver must be operating at the same baud rate so that the receiver knows when to expect the next bit of information. Setting the baud rate correctly for asynchronous serial is very important as the receiver must recover a clock signal from the incoming data based on a predetermined clock frequency. This value than gives you actual T Q time (T Q TIME = 2 * (BRP + 1) / FREQUENCY). One is serial and other one is parallel, When digital data is transferred serially, it is transmitted bit by bit, whereas in parallel transfer, many bits are transmitted at same time. The baud rate specifies how fast data is sent over the bus and it is specified in bits per second. 0 BLE protocol. Therefore, baud rate is always less than or equal to the bit rate but never greater. Thus, the gross bit rate is: R = baud rate x log 2S = baud rate x 3. for 9600 baud rate load 0xFD. The time each bit is present for (the bit time) is the reciprocal of the baud rate - baud rate = 1 / bit time bit time = 1 / baud rate Asynchronous Serial Timing A transmitting device should send its data at a specific baud rate with the correct bit time but that the bit timing actually used may sometimes be too short or too long. Baud rate: The approximate rate (in bits per second, or bps) at which data can be transferred. For example, a 300 bps modem also had a baud rate of 300. Gilmer Market is growing and property values are steadily going up this is the perfect time to start investing here. At that time, data transmitted was measured both in symbols and bits where one symbol could only contain one bit. TOUCAN Module: IPT = 3 TQ if the Baud Rate Prescaler = 1 (MCU system clock equals CAN system clock. AT+CIOBAUD=9600. But you can go lower. To measure the serial bit rate (same as baud rate for this tool), simply connect the ground wire of the tool and target project together. The closest integral baud rate prescaler is calculated for each value. 4k, and 115. The time, p, is the number of instruction cycles from the end of the start bit to the beginning of the stop bit. Using those 9600 baud, only 9600/10=960 characters per second can be send (each character needs 8 bits, plus one start and one stop bit) If I want to add ferrite beads to the input to filter for EMI, I not only need to take the maximum signal frequency into account, but also x harmonics to allow the signal to rise at a decent rate. Note the max cable length (as given by T bus_time) below. Open Terminal and type screen /dev/cu. IEEE JOURNAL OF SOLID-STATE CIRCUITS, VOL. Online calculator to convert bits per second to Megabytes per second (bps to MBps) with formulas, examples, and tables. Hi all, I'm using Visual Studio C# 2005. PDF Download) Aug 28, 2014. BSL_STEP 2 0xXXX 10 -bit value (LSB aligned) to be programmed into selected USIC channel(s FDR. I try to communicate with a PDA, HP iPaq, through the serialport. It was much more relevant when line signalling was used at rather slower rates. The basic unit is the number of bits per second. Only in modems does the bit rate differ f rom the baud rate. SPEN (bit 7) of the RCSTA register enables RC6 and RC7 as serial port pins. In this circuit, the symbol rate is the same as the bit. Now it's time to decide what we want to change. There is nothing defining hertz as anolog, and since in this case a "bit" is 1, the two units are equal. The goal of this article is to teach you how to use price to earnings ratios (P/E ratios). So a "time to send" over an async serial connection can only come up with a minimum time, and is unbounded on the max time. so we use 2 voltage ( 1 positive ,1 negative for 1 bit). The time each bit is present for (the bit time) is the reciprocal of the baud rate - baud rate = 1 / bit time bit time = 1 / baud rate Asynchronous Serial Timing A transmitting device should send its data at a specific baud rate with the correct bit time but that the bit timing actually used may sometimes be too short or too long. It is named after the French scientist: Emil Baudot, who devised one of the earliest data transmission codes, ie: Baudot Code. g 9600 baud rate, than the total time could be calculated as under. Interesting is, that RS232 is the only interface capable of full duplex communication.  Baud is related to gross bit rate expressed as bits per second. You could create another baud rate calculator taken from any 8051 based MCU, matching the timer intervals to the baud rates. General Motor's 160 Baud ALDL Data Stream can be read with a standard serial port running at a rate of from 1600 baud or above. Baud rate can never be less than Bit rate C. The app save and email your rate sheets. The default baud rate of COM1 is 9600. Bit Rate [Baud Rate * Signal Unit]: 4000 bps (bits per second) Bit rate and Baud rate, these two terms are often used in data communication. This tool also provides estimated file transfer time over some of the commonly used network links and computer interfaces. If the baud rates (and thus the bit periods) are different, each sampling point will move gradually closer to the bit transition. The possible output frequencies correspond to 110, 150, 300, 1200, and 2400 Baud. 8051 Baud Rate Calculator.

No setting is necessary. The baud rate value is used to calculate an appropriate clock divisor value to implement the desired baud rate. (I will show you how to calculate the baud rate later though). To achieve a high baud rate you simply double the preceding rate, by this getting the following set of rates - 600, 1200, 2400, 4800, 9600, 19200 and 38400, the last rate. The baud rate, which is also known as symbol rate, measures the number of symbols that are transmitted per unit of time. Bits per second is straightforward. 9600 baud = 9600 bits per second or approximately 0. AVR microcontroller has a register called UBRR(UART baud rate register). I am able to get what all calculation is done out there in this doc. Keil Software provides a baud rate calculator you may use to determine the best baud rate to use for your target application. In the serial port context, "9600 baud" means that the serial port is capable of transferring a maximum of 9600 bits per second. Real Time Electronic Circuit Simulator. 1 Attributes of the MSP430 UART The following is a short overview of the USART. If N bits are conveyed per symbol, and the gross bit rate is R, inclusive of channel coding overhead, the symbol rate fs can be calculated as: fs = R/N}. (Analogous to two passengers per carriage in a train) and here r is two. Debugging With Serial Print At 5333333 Baud. Interesting is, that RS232 is the only interface capable of full duplex communication. This is a modified internet example code using AltSoftSerial on baud rate 57600, upload the code after setting the baud rate and hit Arduino’s Reset button. Repay IN FULL or it's 28. The number of time quanta per bit (known as the bit time) can range from 8 to 25. Baudrate synonyms, Baudrate pronunciation, Baudrate translation, English dictionary definition of Baudrate. I started with a baud rate of 9600, and as I quickly wave my hand in front of the sensor half the time it doesn't register. Thanks to Pedro Zorzenon Neto -- pzn at debian. , 0’s and 1’s) transmitted in per unit time. In a line code, these may be M different voltage levels. The MB Time Calculator can be used to compute CAN bit timing parameters for Microchip Technology MCP2510, MCP2515, and PIC18F CAN controllers, with both legacy and ECAN supported. The standard method for determining the master’s bit rate is to measure the time from the first falling edge to the fifth falling edge. Uart Baud Rate Clock Frequency. , 0's and 1's) transmitted per unit time. The baud rate is the s. 2K bps automatically. The automatic baud rate detector of the present invention determines the baud rate, or bit rate, of a digital serial input data stream by measuring the time duration that the data stream is low during exactly one bit period. T = 15, does not refer to transmission protocol. The time req to transmit one bit is 1/9600 i. This includes functions for calculating USART baudrate or UBBR values, TWI bitrate or frequency calculation, ADC values, ISR vectors, etc…. FORUM THREADS. second, with a unit of bit/sec, commonly known as baud rate or bit rate. Therefore, baud rate is always less than or equal to the bit rate but never greater. Packet loss, jitter, and latency all add up to corrupt a fax transmission over VoIP. The baud rate represents the rate at which serial data is transported over a communication channel. @RWoerz said in Sensebender Micro Baud Rate Issue. How fast is 60 WPM in terms of baud?. Each Bit Timing Segment is made up of integer units of time called Time Quanta (TQ). Unfortunately his marketing skills are a bit Rusty so I jumped in to help him out The property is in a amazing location with a 3% vacancy. Baud rate is usually expressed in bits-per-second and its standard value. Keil Software provides a baud rate calculator you may use to determine the best baud rate to use for your target application. 1 Mbps = 1024 Kbps). The BRP and Tq/bit values are then used to calculate the actual sampling bit rate. Assignment 5. Circuits then use different modulation techniques to carry multiple bits per symbol. Another improvement is to sample the START bit three times (clock counts 7, 8, and 9, out of 16) instead of sampling it only at the midbit position (clock count 8 out of 16). 3 BTS to NULS - We are providing BitShares to NULS converter tool with real-time online exchange rate calculator. Serial Hardware Overview. If you use the width of the first start bit to auto-detect the baud rate, you have 8 bits equivalent of time to translate the width to the baud rate and setup the generator. Baud Rate The baud rate specifies how fast data is sent over a serial line. Each Bit Timing Segment is made up of integer units of time called Time Quanta (TQ). Baud rate is the speed at which data is transmitted over a channel. The Baud rate table (Table 34-4. The max baud rate of the most serial ports and usb to serial ports is 115200. Unless you are doing some fancy coding the basic symbol is going to be the bit and the Baud rate will be the same as the bit rate. 80-250MHz bandwidth, minimum measurement range 500μV /div，1GS/s sample rate，advanced digital trigger system, high trigger sensitivity, low trigger jitter，high resolution 7 inch 64K color TFT （800*480）. the baud rate is measured several times during the synchronization data reception, and is compared each time to the previous measurement. 26us so by using 2 bit periods you will increase the time to 16.

Online calculator to convert bits per second to Megabytes per second (bps to MBps) with formulas, examples, and tables. This utility program calculates baud rates for 8051-compatible serial ports operating in Mode 1 using: Timer 1 Mode 2 with SMOD = 0. But for two-way communications, the baud limit is 1200 baud. None of the above asked Sep 19, 2017 in Computer Networks by sh!va Boss ( 31. The receiving sensitivity of module at different baud rates in the air is shown in the table below:. The term baud rate has sometimes incorrectly been used to mean bit rate, since these rates are the same in old modems as well as in the simplest digital communication links using only one bit per symbol, such that binary "0" is represented by one symbol, and binary "1" by another symbol. The actual bit rate corresponding to B38400 may be altered with setserial(8). The baud rate is selectable from 150 bps up to 19. This is a modified internet example code using AltSoftSerial on baud rate 57600, upload the code after setting the baud rate and hit Arduino’s Reset button. I suppose for inner MCU communication you can achieve very high data rates using floats. -- -- works by having two counters, -- fast counter, counts down to x time baud rate -- slow counter, then divides this to give baud rate. In ASK the baud rate is the same as the bandwidth, which means the baud rate is 4000. I used a simple latency tester which configured all the linux side things optimally (sched_fifo, priority 99, cpu_dma_latench 0us, mlockall). You can measure the actual baud rates of the two uCs using a scope, logic analyzer, or frequency counter. Data speed used to be specified in terms of baud, which is a measure of the number of times a digital signal changes state in one second. A traditional savings account averages 0.
