making it simple...
Library Example
The code is a simple demonstration of CANSPI protocol. It is a simple data exchange between 2
PIC's, where data is incremented upon each bounce. Data is printed on PORTC (lower byte) and
PORTD (higher byte) for a visual check.
char data[8],aa, aa1, len, aa2;
long id;
char zr;
const char _TRUE
const char _FALSE = 0x00;
void main(){
TRISB = 0;
Spi_Init();
TRISC.F2 = 0;
PORTC.F2 = 0;
PORTC.F0 = 1;
TRISC.F0 = 0;
PORTD = 0;
TRISD = 0;
aa = 0;
aa1 = 0;
aa2 = 0;
// Form value to be used with CANSPIInitialize
aa = CAN_CONFIG_SAMPLE_THRICE
CAN_CONFIG_PHSEG2_PRG_ON &
CAN_CONFIG_STD_MSG
CAN_CONFIG_DBL_BUFFER_ON &
CAN_CONFIG_VALID_XTD_MSG;
