Rust VEML6030 High Accuracy Ambient Light Sensor Driver

This is a platform agnostic Rust driver for the VEML6030 high accuracy ambient light sensor using the [embedded-hal] traits.

This driver allows you to: - Enable/disable the device. See: enable(). - Read the measured lux value. See: read_lux(). - Read the white channel measurement. See: read_white(). - Read the measured ALS value in raw format. See: read_raw(). - Calculate the compensated lux for a raw ALS value. See: convert_raw_als_to_lux(). - Set the gain. See: set_gain(). - Set the integration time. See: set_integration_time(). - Set the fault count. See: set_fault_count(). - Enable/disable and configure power saving mode. See: enable_power_saving(). - Enable/disable interrupts. See: enable_interrupts(). - Read the interrupt status. See: read_interrupt_status(). - Set the high/low thresholds in lux or raw. See: set_high_threshold_lux(). - Calculate the compensated raw threshold value ahead of time. See: calculate_raw_threshold_value().

Introductory blog post

The device

Vishay's VEML6030 is a high accuracy ambient light digital 16-bit resolution sensor in a miniature transparent 2mm x 2mm package. It includes a high sensitive photodiode, a low noise amplifier, a 16-bit A/D converter and supports an easy to use I2C bus communication interface and additional interrupt feature. The ambient light result is as digital value available.

Datasheet: - VEML6030

Application Note: - Designing the VEML6030 into an application

Usage

To use this driver, import this crate and an embedded_hal implementation, then instantiate the device.

Please find additional examples using hardware in this repository: [driver-examples]

```rust extern crate linuxembeddedhal as hal; extern crate veml6030; use veml6030::{SlaveAddr, Veml6030};

fn main() { let dev = hal::I2cdev::new("/dev/i2c-1").unwrap(); let address = SlaveAddr::default(); let mut sensor = Veml6030::new(dev, address); sensor.enable().unwrap(); loop { let lux = sensor.read_lux().unwrap(); println!("lux: {:2}", lux); } } ```
