Read analog port set as output I have a PWM analog port that is outputting a frequency, is it possible to do an analogRead on the same pin and get a correct value? If so, will reading that port disrupt the freq output on the pin? This is being done on a Teensy 3.2 device. My goal is to output the freq visually on an OLED. Tnx.
No, it's not possible.

PWM is not actually analog - it's digital, but switching on and off at a high speed.

If the pin were capable of reading an analog value at the same time as outputting a PWM waveform (which I highly doubt...) all you would get is alternating 0 and 1023 values (or whatever range the Teensy reads in).
