Summary
Lab 3 introduces two-dimensional parity error checking for an original 30 byte transmission between a client computer and a PIC32 server. The two-dimensional parity checking code allows us to encode our original message with redundant bits to detect errors in a received message. The original message is arranged in a grid and the parity bit is calculated across the rows and down the columns. Our original 30 byte string increases in size to a 35 byte string that contains the parity information. We demonstrate that our two-dimensional decoder is capable of detecting and correcting one bit errors from the client received message.
