(Arduino Mega)
Using Timer 1, Timer 3, Timer 4 and Timer 5 in the microcontroller to generate 6 varying PWMs
PWMmicros: PWM period is in Micro Seconds. Uses 256 as prescaler for the counter.
PWMmillis: PWM period is in Milli Seconds. Uses 1 as prescaler for the counter.
Both PWMmicros and PWMmillis generate same waveform with timing change.
Counter calculation:
counter = (frequency * time)/prescaler
Default prescaler values: 1, 8, 64, 256, 1024
Max counter Values
- 16Bit: 65536
- 8Bit: 255
