I currently have a setup where I take serial output from Arduino 1 and push it through a transmitter to the receiver of Arduino 2 where it is fed back into the serial input and further processed. I want to ensure that there is as little error as possible and recover the data wherever possible. I have come across the syndrome decoding technique which seems to be the ideal one for me, but I am confused as to how I would go about implementing it. I know that the Arduino Serial transfers data byte by byte, each being 8 bits, but do not know how this data is sent over the serial connection (i.e. How the start & stop bits & parity is implemented). I would assume that a solution to this could either involve modifying the data in the buffer or reading it from the buffer and then operating upon it.

Read about 'Serial Config help.' On element14.com. Moncrief Furnace Manual. I need to configure the Serial on an Arduino to match a very strange Printer. Even parity 'P'. Jul 22, 2016 - Hi Everyone, I've just published a small project on Github involving an Arduino Uno and a Minitel → Since the hardware serial port is taken by the USB connection, I have to use the SoftwareSerial library to communicate with the Minitel. The problem is. Arduino / Arduino. Multi-instance software serial library for Arduino/Wiring. Without even the implied warranty of. These items for its serial interface: - 1 start bit - 8 data bits - 1 stop bit - Odd parity check - No Flow control. I think everything is fine but Odd parity check. I was not able to set the odd parity check to software serial instance. Any idea for communicating with such a device? (like another library or.?!) Thanks.

I could also use adjacent bytes of data for error correction, but this seems wasteful. How should I proceed with this? The datasheet (linked in my answer) has all information about the parity. The parity error detection is done through hardware, and a register is set when the parity didn't match the parity bit. 'Correction' would be re-sending?

As I would consider the byte that caused the error as a lost byte, if you lose one bit in the transmission, you can't be a 100% sure what the character was. Or well, if you only sent 10 types of characters, you can check on which looks the most like the 'wrongly received character'. Though I would encourage re-sending. Also see my answer for the other types of errors. – Jun 2 '15 at 8:01. Easy software solution An easy software solution would be to send the data twice, first receive it and then verify it.

It's highly unlikely that exactly the same bits fail twice. Maybe, for educational purposes, you can try to make an algorithm that sends a checksum. So when sent twice, and received twice (exactly the same), it'll be verified. If this fails, your communication line would be too noisy. Though, for a stable solution, you should always check hardware errors, as some microcontrollers simply stop receiving/sending at a hardware errors. Also if you don't like the overhead of the verification software, hardware errors actually give a good view on what happened and are likely to detect errors even withouth additional software (other than the handling).
