Hi all!, Again me. I've written an ISR that reads Int16 elements from McBSP1 (it's configured through the GUI config tool). It's started in main(). Nothing happens. It seems the ISR is never executed. 1. Which HWI object should be configured for the ISR? (I'm using c5510, I think I need to know the mapping of IER0 and of IER1 bits, so I'll know which bit reflects RINT event from McBSP...)? 2. Do I need to do a C55_plug() call? IRQ_enable? IRQ_map()? (I know some of them are irrelevent when using the GUI config tool...) 3. Maybe I should write everything myself and not configure this ISR thourh GUI config tool? Thank you for your time, David Ganor |
