CAN API reference

See the following example for sending a data telegram to the connected CAN bus.

#include <AnaGateCANDll.h>

int main()

{

char cMsg[] = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 };

int hHandle = 0;

int nRC = 0;

int nFlags = 0x0; // 11bit address + standard (not remote frame)

int nIdentifier = 0x25; // send with CAN ID 0x25;

int nRC = CANOpenDevice(&hHandle, TRUE, TRUE, 0, "192.168.0.254", 5000);

if ( nRC == 0 )

{

// send 8 bytes with CAN id 37

nRC = CANWrite( hHandle, nIdentifier, cMsg, 8, nFlags );

// send a remote frame to CAN id 37 (request 4 data bytes)

nRC = CANWrite( hHandle, nIdentifier, cMsg, 4, 0x02 );

CANCloseDevice(hHandle);

}

return 0;

}

Remarks

The CANWriteEx function is supported by library version 1.4-1.8 or higher.

For devices of type AnaGate CAN (hardware version 1.1.A) the function CANWriteEx is equal to

CANWrite, the return values pnSeconds and pnMicroSeconds will remain unchanged.
