Hello Everyone, I am trying to develop a programme the takes packetized data from the inbuilt UART of the 16F877 which can be anything up to 100 bytes long and then re-packetize it to be sent using a four bit nibble to another PIC but these packets can be up to 27 bytes long. I have to re-assemble the origonal packets at the other end of the link as well. Does anyone know the easiest way to re-format packetized data??
