We are using Router DR in combination with the PC Driver.
We have observed that the CAN_ERR_QXMTFULL error of the API is not related to the physical drop of a frame on the physical canbus. Is there a way to get a real status of the TX buffer ?
Who many elements are bufferd inside the unit on TX side to CAN ?
Is there a way to infuence this setting?
CAN Buffer inside Router DR
Re: CAN Buffer inside Router DR
Hi,
where do you get the CAN_ERR_QXMTFULL error? On the PC side with the PCANBasic API or on the Router DR?
On the PC side, the driver has a RX and TX fifo of 32767 CAN Messages.
On the PCAN-Router the RX/TX queue size is set in can_user.h in line 7-11:
