This module provides access to the sigma-delta component. It's a hardware signal generator that can be routed to any of the GPIOs except pin 0.
The signal generation is controlled by the [`setprescale()`](#sigma_deltasetprescale) and [`settarget()`](#sigma_deltasettarget) functions.
* 0 < target <= 128<br />
- 0 < target <= 128<br />
t<sub>high</sub> = (prescale + 1) / 80 µs<br />
t<sub>period</sub> = t<sub>high</sub> * 256 / target
* 128 < target < 256<br />
- 128 < target < 256<br />
t<sub>low</sub> = (prescale + 1) / 80 µs<br />
t<sub>period</sub> = t<sub>low</sub> * 256 / (256 - target)
* target = 0<br />
- target = 0<br />
signal stopped at low
Fixed frequency PWM at ~312.5&nbsp;kHz is availble with the [`setpwmduty()`](#sigma_deltasetpwmduty) function.
