Since LCK_pend and LCK_post can not be used in HWI/SWI, is there any other way to achieve something like resource lock between HWI/SWI  and TSK?

LCK HWI SWI TSK resource lock

    Hi Yiran,

    Have you considered using the Semaphore (SEM) module ?

    Thank you for your reply.

    I will consider your suggestion. I need some time to re-design my program. If I make any progress, I will update the post.

    I review the DSP/BIOS API Reference Guide, and I think it is easy to design a resource lock mechanism by using binary semaphore.

    Thanks a lot.
