i'm using the 20Mhz crystal in PIC18f26k22 controller fro serial communication program. the aim of program is to receive data from the Hercules to PIC and send same data back to Hercules while using serial communication i try to receive serial data at baud rate of 19200. but as i use reception time out count value 866 (which is (...)
If you are getting some odd symbols on the display, then it suggests that the baud rate is correct (likely) but you have problems with stop bits, parity and no of bits etc. Also see that the bitwise connections again and again...
baud rate is equivalent to bit rate for a binary encoded signal. So time period of 1 bit = 1/ baud rate
Hello, Am using UART for an applications, the Peripheral clock is 32Mhz and the baudrate is 800000bps. My doubt is- how to calculate 1 bit time of transfer. I need to calculate for 256 bytes of data. Regards JD
more commonly today Symbol rate= baud rate is only same as bit rate using 1 bit per symbol. Compression methods include N level amplitude and phase point to represent many bits into one symbol to maximize bandwidth (...)
Actually i am getting problem while trying to receive the incoming sms from gsm modem to micro controller controller-lpc2148 Uart- UART0 //Cpu clock-60 Mhz (using PLL 12Mhz*5=60Mhz) VPB -15mhz //9600 baud rate ,8 bit data,1 stop bit,no parity Enabled interrupt-Rx0 i have attached my code (...)
Firstly, the STM8S is not an ARM core architecture, but a propriety 8-bit microcontroller core designed by ST. Secondly, to maximize the baud rate, TX/RX distance and decrease the susceptibility to RF noise, typically you will need to implement some method of encoding, like Manchester Encoding, when utilizing ASK/OOK RF (...)
I don't see a problem with the code. Writing to TXIF is useless, but doesn't hurt (bit is RO, see datasheet). It's cleared automatically when the TXREG data is transferred to UART shift register. So consequently, you wait for TXIF being set before writing to TXREG. May be wrong baud rate? Or receiver set to (...)
A signal has a bit rate of 20 kb/s. Find the baud rate if the signal is transmitted using: a. FSK with two frequencies b. QPSK with four phase angles c. QAM with four phase angles and four amplitudes
You can achieve the fast (double) baud rate setting by setting PCON register bit 7 respected FvM sir suggested data sheet helps you more refer it.
I have read in various literature books that the baud rate generator in a UART module should generate a signal whose sampling frequency is exactly 16 times the UART's designated baud rate. For a 57600 baud (...)
Yes, the baud rate is the number of bits-per-second. Stop bits can generally be selected to be 1, 1.5, or 2 bits long. It's a bit confusing because the selection of number of stop bits only affects the transmission. If you expect to receive 1 stop (...)

assuming typical RS232 transmission each character transmitted is 10bits (8 data, 1 start and 1 stop bit), i.e. 115200baud can transmit a maximum of 1152 bytes/second (assuming that the receiver can accept data at that rate and not get overruns). you are sampling 3200 samples/second - how may (...)
hi,i am usig ARM CORTEX M3 LPC 1788 for UART communication.But i am getting confuse how to manage or set the start bit.there is a function for stop bit,parity bit and baud rate but not with start plz help me.
hi vikky, The usual causes of corrupt RS232 data are in the baud rate settings not being the same or the Parity bit ie: Even or Odd or Off. On your scope you should see for each character, a 10 bit long string, 1 Start bit, 8 data bits and 1 Stop bit. On (...)
could anybody explain me the factors that decide the baud rate on which a communication device works? Thanks in advance!
It sounds as baud rate of UART transmitter and receiver configured at different rates. +++
Yes,it's possible. buy usb parallel converter and if your pc has a parallel port it will be much easier baud rate will not be a problem if you have in your design a hold bit control .just tell me if you have a parallel port or not if not check at any computer store if they have a usb multi connection(parallel serial vga) if (...)
I have this 3-axis dongle serial accelerometer connected using RS-232 cable. I am putting the baud rate as 9600 and im getting 80 XXXX-YYYY-ZZZZ raw data readout per second. I am trying to justify why does it shows 80 readings in a second, and here is my calculation, 2 Bytes of data x (1 Start bit + 1 Stop (...)
