AT42QT2120 Rust driver

Platform agnostic Rust driver for the AT42QT2120

The AT42QT2120

The AT42QT2120 is a touch driver with 12 channels, of which 3 can be used as a slider or a wheel. It has an I2C interface. Datasheet: http://ww1.microchip.com/downloads/en/devicedoc/doc9634.pdf

Status

Basic support works and is tested on hardware:

• Support reading keys
• Support reading raw key values
• Support reading slider
• Configurable slider/wheel
• Configurable key threshold
• Enable/disable keys
• 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.
