[SOLVED] [Moved] SPI communication between two PICs in MikroC (PIC18F452)

[amila133]

These are my successful mikroC program codes.

Pls find the attachments.

FOR Master

unsigned char count=0;
unsigned short receive;
void send_data();


void main(){

    ADCON1=0x06;
    TRISA=0xff;
    Spi_Init_Advanced(MASTER_OSC_DIV4,DATA_SAMPLE_MIDDLE, CLK_IDLE_LOW, LOW_2_HIGH);
/*while(1){
           if(PORTB.f0){

            count=count+1;
            Delay_ms(250);
            if(count==10){
            PORTD=count;
            
          send_data();
          }
            }


            } */

thank you very much but you can add the schematic of the circuit
