Which frequency the timer will try to sample

Variants

Frequency(Hertz)

In this mode an algorithm calculates the optimal value for the autoreload register and the prescaler register in order to be able to sample a wide range of frequency, at the expense of resolution.

The minimum frequency that can be sampled is 20% the provided frequency.

Use this mode if you do not know what to choose.

DutyCycle(Hertz)

In this mode an algorithm calculates the optimal value for the autoreload register and the prescaler register in order to sample the duty cycle with a high resolution. This will limit the frequency range where the timer can operate.

The minimum frequency that can be sampled is 90% the provided frequency

RawFrequency(Hertz)

In this mode an algorithm calculates the optimal value for the autoreload register and the prescaler register in order to be able to sample signal with a frequency higher than the provided value : there is no margin for lower frequencies.

RawValues

In this mode, the provided arr and presc are directly programmed in the register.

Fields

arr: u16

presc: u16
