This crate contains a platform-agnostic driver for the MCP346[1/2/4] Sigma-Delta ADC, using the [`embedded-hal`](https://github.com/rust-embedded/embedded-hal) traits.

Currently, you can:

- Initialize the device
- Configure Input MUX and IRQ Pullup
- Set the conversion or power down mode
- Obtain measurements

### [Documentation](https://docs.rs/mcp346x)


## Usage

### Single Measurement

```rust ignore
use mcp346x::*;

let spi_pins = (sck, miso, mosi);
let spi = Spi::new(p.SPI0, spi_pins, Frequency::K500, MODE_0);

let address = 0b01; // This is the default address for most chips
let mut adc = MCP346x::new(spi, address).into_continuous_mode()?;

adc.set_clock_source(mcp346x::ClockSource::Internal)?;
adc.set_irq_internal_pullup(true)?;

let voltage = adc.measure()?;
```

## Status

- [x] Initialization
- [x] Powerdown/wakeup/conversion
- [x] Take Measurements
- [x] Input MUX configuration
- [ ] SCAN mode
- [ ] Expose other Configurations
- [ ] Communication CRC checksums
