yes pretty much. //TEENSY 4.1 #include <Arduino.h> // Digital and PWM pins const int numDigitalPins = 42; // D0 to D41 int digitalPins[] = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28...

? what do you mean? Yes the scope was grounded corredtly both measurments.

Hey guys! just curious, did run a quick pin test on a teensy 4.1 coz of strange behavior. code runs through all pins and sets digital to high for 5ms then low 5ms and then tests PWM. on a working pin it looks and works great see image 1 on pin...
