The documentation for this library should cover everything you need to know about the chip and its i2c registers.

## Usage

A usage example is given in the `examples` folder.

### Requirements

* Embedded Hardware Abstraction Layer support crate for your device (i.e. atsamd for SAM family devices)
* A bq24195 chip connected over I2C

### Building and Flashing


#### Arduino MKR Vidor 4000

This should also work on other SAMD21 boards.

```bash
RUSTFLAGS='-C link-arg=-Tlink.x' cargo build --release --target thumbv6m-none-eabi --example arduino_mkrvidor4000
arm-none-eabi-objcopy -O binary target/thumbv6m-none-eabi/release/usbblaster-rs target/usbblaster-rs.bin
# Manual step: push reset button twice in quick succession to enter flash mode
bossac -i -d -U true -i -e -w -v target/usbblaster-rs.bin -R
```
