This crate implements a driver for the HRTIM peripheral found in select devices from F3, G4 and H7 series of STM32 microcontrollers. The HRTIM peripheral is a high resolution timer that allows precise control even at higher frequencies.
The HRTIM is primarily intended to drive power conversion systems such as switch mode power supplies or lighting systems, but can be of general purpose usage, whenever a very fine timing resolution is expected. It is very flexible allowing complicated waveforms and suport connections to various other peripherals like DACs, ADCs, comparators, other timers, DMA etc.
🚧 Work in progress
This crate is being developed and lots of things are still subject to change. It should still be considered quite experimental. Use with cation.

This driver is intended for use through a device hal library. See stm32g4xx-hal as a reference.
TODO update link once stm32-rs/stm32g4xx-hal#192 is merged.
