I count cycles to output timecode (SMPTE 12M). Other manufacturers have crystals of exactly 0.2ppm. This allows for drift of no more than 1 frame per day. With the current crystal of 10ppm, the drift is too large. Therefore, I need to count as accurately as possible. Since I use timers, I am looking...

I use hardware timers bitTimer = timerBegin(0, 2, true); timerAttachInterrupt(bitTimer, &timerESP, true); timerAlarmWrite(bitTimer, halfBit, true); timerAlarmEnable(bitTimer); My board uses a 40 MHz 10ppm crystal, I want to improve the accuracy of the timer. From the documentation I understood that ...
