Crate mpr121_hal

MPR121-Hal

This crate follows the Adafruit implementation closely but exposes it in terms of the embedded-hal project.

The main responsibility of this crate is returning the current on/off state of all the (up to) 12 pins.

The chip’s data sheet can be found here. The implementation however mostly mirrors the Adafruit implementation, since this is probably the most widely used one.
