I’m using the example code. This compiles fine. But I can’t change the LED_BUILTIN to a digital pin PIN_Dx. Analog pins are define PIN_A0 works. Is this normal behavior?
Do you have
board = teensy36 in your
platformio.ini? That example contains a typo and sets
teensy35 in the Teensy 3.6 environment
Just checked. Yes, it’s set correctly.
Apparently analog pins are PIN_Ax and digital pins are just numbers.
