So I can’t use two PWM pins independently if the TIM’s are the same or if the CH’s are the same?

EDIT:
So TIM4_CH2, TIM4_CH1, TIM3_CH2, TIM3_CH1 could all work independently?

I just read this on the Particle Docs:

PWM is available on D0, D1, D2, D3, B0, B1, B2, B3, A4, A5, WKP, RX, TX with a caveat: PWM timer peripheral is duplicated on two pins (A5/D2) and (A4/D3) for 11 total independent PWM outputs. For example: PWM may be used on A5 while D2 is used as a GPIO, or D2 as a PWM while A5 is used as an analog input. However A5 and D2 cannot be used as independently controlled PWM outputs at the same time.

A5 and D2 are TIM3_CH2 and TIM3_CH2. That makes sense.

@ScruffR

The pins with TIMx_CHy are PWM pins and this even tells you what timers/channels are used to see which PWMs are independetly usable and which aren't (same TIM/CH combo).

I see what you mean now. If the TIM and CH on two PWM pins are the same they can not be used independently.

When they are not the same.

@ScruffR

and which aren't (same TIM/CH combo)

aren't [usable independently] equals same combo

Yeah… Thanks for clearing up my confusion.
