can't sent CAN message under 75kHz closed-loop control application

[tckwok]

I am now using the Kinetis KV series for a digital power converter. The firmware structure is a simple background/ISR combination. The ISR is for 75kHz closed-loop control, and the code works fine without adding the function that sends CAN message.

When I initiated a separate project that only does CAN message sending and receiving, things are going pretty well. But when I migrated the function to the closed-loop project, the background main() seems to be stuck.( the 75kHZ ISR is still working !!!)

Are there any things I am missing?

Hi Zabel A,

   When you migrated the function to the closed-loop project, the background main() seems to be stuck, do you debug the code, where the code is stopping?

   Do you also try add some of the closed-loop project function to your working CAN project?
