Which frequency the timer will try to sample

Variants

Frequency(T)

Tuple Fields

0: T

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(T)

Tuple Fields

0: T

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(T)

Tuple Fields

0: T

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

Fields

arr: u16

presc: u16

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