lis2dw12

A no_std compatible Rust driver for the low power ST 3-Axis MEMS 14-bit accelerometer LIS2DW12 using the SPI bus

Example

// create the device
// where spi implements Transfer<u8, Error = SpiError>,
// and cs implements OutputPin<Error = PinError>
let mut accel = Lis2dw12::new(spi, cs);

// confirm that communication is working
accel.check_who_am_i()?;

// set up the device
accel.set_operating_mode(OperatingMode::HighPerformance)?;
accel.set_low_noise(true)?;
accel.set_full_scale_selection(FullScaleSelection::PlusMinus2G)?;
accel.set_output_data_rate(OutputDataRate::Hp100HzLp100Hz)?; // 100 Hz

// get raw data
let raw = accel.accel_raw()?;
rprintln!("raw: {:?}", raw);

or take a look at a working example using an STM32 bluepill here

Note that this crate implements the traits in the accelerometer crate. If you have problems figuring out how to propagate errors then take a look at the bluepill working example linked above.

Features

This crate implements the RawAccelerometer<I16x3> trait by default. If you want need the Accelerometer trait then enable the out_f32 feature. For example:

# cargo.toml
lis2dw12 = { version = "0.1.0", features = ["out_f32"] }
