ChibiOS Free Embedded RTOS

Hi,

I use softwer UNI/O protocol. I need to disable all interrupts (including OS interrupts) except to interrupt TIM3. And later, enable back. How can I do it at ChibiOS?

hi,

You could put TIM3 IRQ priority at maximum, other IRQs would not interfere with it.

If you need to disable other interrupts there is no other way except to disable the sources one by one operating on NVIC.
