Hi! This is my first try on SPI communication. As title says, I have a PIC connected to my UNO. The idea is to send numbers from the PIC to the UNO via SPI and from there on to my PC via Serial.print . The PIC is powered from the UNO.
I can't get my codes to work however and have no idea what is wrong.
Code on PIC (master):
unsigned char i = 0;
void init(void)
{
ADCON0 = 0;
ADCON1 = 0b0000111;
TRISC.B3 = 0; // SCK
TRISA.B5 = 0; // _SS
TRISC.B5 = 0; // SDO...
