I don’t know if what I want to do can be done.
I got this particle sensor for air quality:
It has a really simple pinout- VCC, Gnd, RX, TX. It has a PWM pin.
I want to capture the serial output and figure out how to parse it.
I see someone used Software Serial, but he used stuff you don’t have to do correctly in Arduino, which doesn’t fly in PIO.
Do you know how to do this?
