KE06Z Processor Expert - Send CAN Frame Issues

michaeljwilson — Tue, 08 Jan 2019 19:26:10 GMT

Hello all, I'm working on a KDS 3.0 Processor Expert project using the FRDM-KE06 board for CAN development.

I am able to configure the board on a basic level but have trouble sending and receiving CAN messages, both the RX and TX interrupts don't trigger and it seems as if the KE06 is resending the same message. (CAN Statistics show 86% bus load). When I add another node, the KE06 begins to send error frames. I'm not sure what is going on here. Please see the attach KDS project.

Note: I have seen other posts about a possible bug where PEX doesn't generate the code in CAN_Init.c. that was shared by Alice_Yang https://community.nxp.com/thread/386975, I tried that.

I think I may have a different issue here.

HI Michael,

NXP recommend customer to use MCUXpresso IDE software and MCUXpresso SDK package for KE06 product.

If you are using KE06 product for new product design, I would recommend to use MCUXpresso IDE and MCUXpresso SDK software package.

There with very limited support resource of KDS IDE and Processor Expert tool so far. Sorry for the inconvenience.

I will check your code and reply later.

Thank you for the patience.

Have a great day,
Mike

Hi,

I test attached code with FRDM-KE06Z board and get below CAN frame.

I don't find there with the error message.

If you want the eight byte be 0x7, please mask below code with red block:

Wish it helps.

Have a great day,
Mike
