ISR in C?

Can someone tell me if you have to have the Interrupt Service Routine written in assembly

in MicroC/OS-II?

The book says that they need to be but I found that surprising.

It seems all the other HAL functions to enable ISR's are in C so I wrote mine in C. It does not work

yet but that could be many other problems. I wanted to know before I converted the ISR to assembly.

Thanks

    Hello,

    Could you give me the link of the old post please ? I&#39;m trying to implement ISR in C but it doesn&#39;t seem to work.

    Regards.
