17.4.17 CANopen fall-back SDO handler callback
}
Remark: If the flag isr_handled was set TRUE when initializing CANopen, this callback
function will be called by the CAN API interrupt handler and therefore will execute on the
interrupt level.
The CANopen fall-back SDO handler callback function is called by the CANopen handler.
This function is called whenever an SDO request could not be processed or would end in
an SDO abort response. It is called with the full data buffer of the request and allows to
generate any type of SDO response. This can be used to implement custom SDO
handlers, for example to implement the SDO block transfer method.
// Return values for CANOPEN_sdo_req() callback
#define CAN_SDOREQ_NOTHANDLED 0 // process regularly, no impact
#define CAN_SDOREQ_HANDLED_SEND 1 // processed in callback, auto-send
#define CAN_SDOREQ_HANDLED_NOSEND 2 // processed in callback, don't send
