Hello, the PCAN FD hardware calculates the busload in an internal interval of (clock freq/prescaler)*8 and each 4095 intervalls a busload frame is generated. To get the best precision, you have to use each busload frame and build an average over all. If you only poll the busload, you may miss some b...

Hi,

simply use a 1ms sleep, to be sure the frame could be sent on a 500k bus (empty CAN, no arbitration losses!).

How about termination of your cables? A stuff error is mostly a termination issue....

Hi,

please check that you use termination resistors on both ends of your CAN cable. A small sleep between write and CAN_Unitialize() could also help, maybe you close the channel before the frame was fully written to the bus.

Hi, yes, also possible. Your variable must be of type CANTiming_t than: typedef struct { uint32_t can_clk; //!< clock for CAN controller, see CAN_CLOCK_... uint16_t nom_brp; //!< prescaler for arbitration phase ( 1..1024) uint16_t nom_tseg1; //!< Tseg1 for arbitration phase ( 1..256) uint8_t nom_tse...

Hi, looks like you are using the peak-linux-driver. Please post the output of cat /proc/pcan to see which version you are using. With this driver it is possibe to increase the rx buffer or even switch to MSI instead of INTA interrupt handling, to improve such issues. More details are available in th...

Hi,

we can't help in any LabView related issues, but there are ready to use PLIN LabView VIs available by the company KDI/digiinst:

https://www.digiinst.de/c/software

They also offer support for their LabView drivers

Hi,

please open the filters for all messages with SetClientFilter() to be able to read all LIN frames.

About your question of TLINSlotType : please see PLIN API documentation on page 13

Hi,

use LIN_Read() to see the correct LIN frames or errors on the LIN after your Write() commands

Hello, when working with LIN Diagnose frames, IMHO it will be better to not use the scheduler for that. We typical use a multimediatimer and use LIN_Write() to send out the 3C publisher and the 3D subscriber frame. Take care to read the frames with LIN_Read() in a loop using also a multimedia timer ...

Hi, yes, this is possible. You can change the CAN initialization during normal operation by calling: CAN_UnInitialize ( CANHandle_t hBus); followed by CAN_Initialize ( CANHandle_t hBus, const CANTiming_t *timing); with the new settings for your CAN channel. Please see \inc\can.h for more details abo...
