Yes, that's exactly what I'd like to do, but there's no warning from the Arduino IDE. One could manually shut down your software, say through the serial terminal, but leaving the Teensy power on, every time you punch for a new build while...
Well, it's nothing to do with external circuitry, the output bit locks high (or probably low sometimes). This is for instance pin 37 on this T4.1. The pin was set to an output,
const int PINAME = 37;
pinMode(PINAME, OUTPUT);
Then is...
When rebuilding/reloading T4.1 software on the Arduino IDE, the CPU is locked, serial terminal shows greyed out, fine. But the PWM outputs stop PWMing, which causes an annoyance when they stop at 1 (full throttle! Damn the torpedoes!) I...
