## Status
Basic support works and is tested on hardware:
- [x] Support reading keys
- [x] Support reading raw key values
- [x] Support reading slider
- [x] Configurable slider/wheel
- [x] Configurable key threshold
- [x] Enable/disable keys
- [x] Configurable detection integrator

Most advanced configuration is not supported:
- [ ] Configurable drift compensation
- [ ] Configurable touch recal delay
- [ ] Low power mode
- [ ] Using Change pin as input
- [ ] Configurable key oversampling

I am new to Rust, so the code quality is probably not great.
