Hi All,
I have this project where I check several incoming signals with help of interupts and timers and based on that, I output 2 square wave signals with 50% dutycycle but phased/shifted 90°. I'm typically good at (or call it lucky) finding snippets I can make to work for me but this doesn't seem so evident.
I have 1 output working stable by using ledcwrite PWM but struggle to get that second, identical but 90° phased output going. Any tips or suggestions ? As I'm doing these interrupts and timers on the input side, I want to keep processing to a bare minimum.
My code has quite some menustructure with a lot of things embedded in it so will not share the whole thing here but can share extracts where relevant, thanks.
