Hardware questions

Hello Fabiano, thank you so much for the time and effort put into this library, I have a question related to the avr and rp2040, witch pins (gpio) could or should I use for the zero crossing signal and for the control output?

Hello again, I'm having issue with flickering at low voltage adjustment, i'm using a resistive bulb lamp to test, it has about 80w, i'm using an arduino uno, sync pin 3, trigger pin 9, to detect the zero i'm using an p814 opto, with 150k resistor at the input and output with a 10k pull-up resistor, the SCR that I am using is an scr module, configured in anti-parallel mode, I've tried the dimmer mode and linearized mode, also I've tried to activate FILTER_INT_PERIOD but doesn't solve, do you think it may be related with the quality of the ZC circuit ?
