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. 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. The signal generation is controlled by the [`setprescale()`](#sigma_deltasetprescale) and [`settarget()`](#sigma_deltasettarget) functions.
