Check out Arduino For Beginners and learn step by step.So, for the micros() function, you get a resolution of… one microsecond ? Wrong!The resolution for micros() is 4 microseconds on all 16MHz Arduino boards: Uno, Mega, Nano, etc. For example, if you read the time with micros()...
What does not seem to work is the 'run cpu sleep' part. esp_delay above just yields to system for the given duration, function would block and won't return until that time arrives; not really a full-fledged sleep like deep sleep or light sleep without timer. I'm not sure if you me...
My point is this; If you call the checkExpired function when using it in the context of TimeSourceMillis. Then timeType is the same are returned by millis(), so consider it an unsigned long. bool checkExpired(const timeType internalUnit) const { // canWait() is not checked here // ...
