WebMay 6, 2024 · Hi, I have an external device which sends binary data to my Arduino 16 bits at a time. Of these 16 bits, the first bit is even parity of next 7 bits while the last bit is odd parity for the previous 7 bits. I have an idea of how to do this in my head with a loop and a few conditionals but I don't quite understand how I would do this in Wiring.

WebMay 30, 2009 · The number has “odd parity” if it contains an odd number of 1-bits and is “even parity” if it contains an even number of 1-bits. The main idea of the below solution is – Loop while n is not 0 and in loop unset one of the set bits and invert parity. WebParity bits are sufficient to catch all single errors in the pattern plus parity bit as this will change a single 1 to a 0 or vice versa and therefore upset the parity calculation.

"A parity bit, or check bit, is a bit added to a string of binary code. Parity bits are a simple form of error detecting code. Parity bits are generally applied to the smallest units of a communication protocol, typically 8-bit octets (bytes), although they can also be applied separately to an entire message string of bits. The parity bit ensures that the total number of 1-bits in the string is even or odd. Accordingly, ther… " - Calculate the even parity bit p psw.0
