WebThe program gives a list of all possibilities for PSC and ARR. SMT32 background and timers Time base generator. Depending on the clock (TIM_CLK), prescaler (PSC) and auto reload (ARR), repetition counter (RCR) parameters, the 16-bit or 32-bit timer can generate an update event from a nanosecond to a few minutes or wider. TIM_CLK in Hz [1/s] WebThe maximum duty cycle count will be equal to the value that will be set in the timer auto-reload register, TIMx_ARR. In my example, I set PSC zero and ARR 1599 and so now you can see why the PWM frequency is 45 kHz. …

WebJul 15, 2024 · The trivial solution would be to set one of them, e.g. PSC to 0, and ARR to the right hand side value - 1. Unfortunately most timers have 16 bit registers only, so this is not going to work when TIMclk/Updatefrequency > 65535. Both PSC and ARR must fall between 0 and 65535. You'd have to find a factorization that satisfies these constraints. does netflix offer fox newsWeb“PSC” is the prescaler used to divide system clock rate by a given factor to make the timer count.
