Below are functions to set wiz550io as TCP server
Fill free to use they are for MikroC IDE and dsPic in C Any improvemt and suggestion are welcome.
for debug resons I use Uart2 so first of all you have to
Uart2_Init(115200); // DEBUG port use uart2
U1MODEbits.ALTIO = 1; // clear the way for SPIif you don’t like the messages to uart2 then comment the uart lines
to begine TCP server

do{ // Socket 0 initialize
