Macro Definition Documentation

◆ CANRX_CAN_REQUEST_UPDATE_TIME_ms

#define CANRX_CAN_REQUEST_UPDATE_TIME_ms   (3000u)

CAN state request update time.

When a new CAN state request is received, it leads to an update of DATA_BLOCK_STATE_REQUEST_s::stateRequestViaCan if one of the following conditions is met:

  • The new request is different than the old request.
  • The old request is older than the timespan set in this define.
