Question about RTIC and interrupt setup #126

Closed huming2207 closed 2 months ago

huming2207 commented 2 months ago

Hi @newAM

Sorry this might be stupid question. I've got some time recently and I went back learning Rust on STM32WL again. Now I'm just curious how do you set up the interrupts with RTIC?

For example, in the init() routine in your client/src/main.rs, I haven't seen you calling NVIC's unmask() to enable the NVIC for LPTimer or SubGHZ peripherals. I've only seen you called the set_ier() for lptim1. Has RTIC itself done this implicitly when in init()?

Regards, Jackson

Okay I had a read in RTIC issues and I can understand now that I don't (and I shouldn't) touch NVIC stuff as RTIC has done that for me... I will just implement the code like yours without worrying about the NVIC stuff then.

You can expand macros (I forget how off the top of my head) to better see what RTIC does under the hood.

Yea, I forgot that earlier too, I will have a look.
