void CANSetOperationMode(char mode, char wait_flag);
Description Sets CAN to requested mode, i.e. copies mode to CANSTAT. Parameter mode needs to
be one of CAN_OP_MODE constants (see CAN constants).
Parameter
wait_flag needs to be either 0 or 0xFF:
If set to 0xFF, this is a blocking call – the function won’t “return” until the requested
mode is set. If 0, this is a non-blocking call. It does not verify if CAN module is
switched to requested mode or not. Caller must use function
CANGetOperationMode
to verify correct operation mode before performing mode specific operation.
Requires CAN routines are currently supported only by P18XXX8 PICmicros. Microcontroller
must be connected to CAN transceiver (MCP2551 or similar) which is connected to
CAN bus.
Example
CANSetOperationMode(CAN_MODE_CONFIG, 0xFF);

char CANGetOperationMode(void);
Returns Current opmode.
Description Function returns current operational mode of CAN module.
Requires CAN routines are currently supported only by P18XXX8 PICmicros. Microcontroller
must be connected to CAN transceiver (MCP2551 or similar) which is connected to
CAN bus.
Example
if (CANGetOperationMode() == CAN_MODE_NORMAL) { ... };
