delay_us issue

Hi,

I encountered several difficulties by using the delay_us function with the piccolo stick (CCS3.3). I already use the delay_us asm function with a f2808 without having problem.

The dependencies and clock constant seem to be correct, the code compiles without error. At the time I start the program, it appears that the delay_us call are not correctly performed, even if the rest of the program is running ( -> the soft is not blocked in the delay function).

Let me know if you already experiment something like that.

    Jaquier,

    I'm not sure I understand what the symptoms are.  Is the function being called but the time is wrong?  Or the function is not being called at all?
