MCP346x Sigma-Delta ADC

This crate contains a platform-agnostic driver for the MCP346[1/2/4] Sigma-Delta ADC, using the 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

Usage

Single Measurement

```rust ignore use mcp346x::*;

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

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

adc.setclocksource(mcp346x::ClockSource::Internal)?; adc.setirqinternal_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
