WebI was wondering if anyone could explain how to find the priority number, PRI_n of an interrupt given pre-emption priority, subpriority, and PRIGROUP (3-7 for STM32). I understand the PRI_n is the priority for the interrupt and its range is 0 to 255. I took some examples from the STM32 library but I do not understand them.
