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 = 0xFF;

const char

_FALSE = 0x00;

void

main(){

TRISB = 0;

Spi_Init();

// Initialize SPI module

TRISC.F2 = 0;

// Clear (TRISC,2)

PORTC.F2 = 0;

// Clear (PORTC,2)

PORTC.F0 = 1;

// Set (PORTC,0)

TRISC.F0 = 0;

// Clear (TRISC,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;

PORTC.F2 = 1;

// Set (PORTC,2)

// Form value to be used with CANSPISendMessage

aa1 = CAN_TX_PRIORITY_0 &

CAN_TX_XTD_FRAME &

CAN_TX_NO_RTR_FRAME;

PORTC.F0 = 1;

// Set (PORTC,0)

// continues ..
