Thanks! Will do. Andy

When you do need a timer interrupt, use IntervalTimer instead of TimerOne. IntervalTimer uses Teensy's 4 x PIT (programmable interrupt timer), so it generally won't get in the way of what you're doing with other pins.

The TimerOne library uses the same PWM module that controls pin 7, it is stomping over the initial values that you setup.

Yep, that was it! I've changed to elapsedMillis as suggested by @joepasquariello Thanks!

I'm guessing you're new to Arduino, and if so, I'd like to point a couple of ways to simplify your program. All Arduino-compatible boards, including Teensy, have a built-in 1-ms timer that you can read via the function millis(), and you can use...

Hi! Here is my code: #define REAR_DUMP_PWM 7 #define PWM_FREQUENCY_HZ 120 ... analogWriteFrequency(REAR_DUMP_PWM, PWM_FREQUENCY_HZ); analogWriteResolution(15); // 0 - 32767 analogWrite(REAR_DUMP_PWM, (int)(32767 * 0.50)); And here is what I...
