Hello, I have searched the forums for a comprehensive answer to this question, but I could not find any definite info (here or in the docs) about which pins can and should be used for PWM on the RAK3172.
Specifically, I want to know which pins of the RAK3172 can be used with the analogWrite() function in a RUI3-based firmware and under what limitations.
From the Arduino_Led_Breathing example (also described in a forum post), I know that PA0 and PA1 support timer-based PWM via analogWrite() but multiple posts in this forum suggest that not all other GPIOs can be used for this. I need at least one more PWM capable pin for my application.
There is also a post asking pretty much the same question, but it was never answered.
I would like to know if my electronics design will work and if I can achieve the PWM control I need on top of RUI3 or if I need to dive into a lower level to control the timers and muxes myself.
