User manual
17.4.12 CAN error callback
17.4.11 CAN message transmit callback
// CAN receive handler
void CAN_rx(uint8_t msgobj_num)
{
}
Remark: The callback is not called if the user CANopen handler is activated for the
message object that is used for SDO receive.
Called on the interrupt level by the CAN interrupt handler after a message has been
successfully transmitted on the bus.
Example call:
// CAN transmit handler
void CAN_tx(uint8_t msgobj_num)
{
}
Remark: The callback is not called after the user CANopen handler has used a message
object to transmit an SDO response.
The CAN error callback function is called on the interrupt level by the CAN interrupt
handler.
