"Pulse-width modulation (PWM), or pulse-duration modulation (PDM), is a method of controlling the average power delivered by an electrical signal. The average value of voltage (and current) fed to the load is controlled by switching the supply between 0 and 100% at a rate faster than it takes the load to change … See more The term duty cycle describes the proportion of 'on' time to the regular interval or 'period' of time; a low duty cycle corresponds to low power, because the power is off for most of the time. Duty cycle is expressed … See more Pulse-width modulation uses a rectangular pulse wave whose pulse width is modulated resulting in the variation of the average value of the waveform.

WebJan 12, 2024 · To change the duty-cycle to 0, you set the count-control register ( CCR) value to the max value of the timer period (e.g. the rollover value). The duty-cycle is the percentage of time that power is being applied. So if your timer has 16-bit precision (max 32767) and you have a 50% duty-cycle ( CCR = 16384) the power is off from 0 - 16383 … WebNav.

WebFeb 7, 2024 · An example PWM timing diagram . A counter counts up from 0 to an “overflow” value in a modulus register. When the modulus is reached, the counter goes to 0 on the next clock. The modulus here is a value of 9 and the number of states for the counter is 9+1 or 10. The counting simply repeats for as long as the timer is enabled. WebBTW: the first sketch reads value in POTD register, not the value on the actual pin. It might be for example shorted and PIND register would read it correctly. It's possible to read the actual value (by reading PIND) but as Majenko wrote, it's changing, so you'd have to read it at constant rate or measure the low and high time.
