Crate apds9960

This is a platform agnostic Rust driver for the APDS9960 digital proximity, ambient light, RGB and gesture sensor, based on the embedded-hal traits.

This driver allows you to:

• Enable/disable the sensor. See: enable().
• Enable/disable delay between proximity and / or color / ambient light cycles. See: enable_wait().
• Enable/disable long delay between proximity and / or color / ambient light cycles. See: enable_wait_long().
• Set the waiting time between proximity and / or color / ambient light cycles. See: set_wait_time().
• Force an interrupt. See: force_interrupt().
• Clear all non-gesture interrupts. See: clear_interrupts().
• Read the device ID. See: read_device_id().
• Proximity:
  • Enable/disable the proximity sensor. See: enable_proximity().
  • Enable/disable proximity interrupt generation. See: enable_proximity_interrupts().
  • Enable/disable proximity saturation interrupt generation. See: enable_proximity_saturation_interrupts().
  • Read the proximity data. See: read_proximity().
  • Check whether the proximity data is valid. See: is_proximity_data_valid().
  • Set the proximity interrupt low/high thresholds. See: set_proximity_low_threshold().
  • Set the proximity offsets. See: set_proximity_offsets().
  • Clear proximity interrupt. See: clear_proximity_interrupt().
• Color / ambient light:
  • Enable/disable the color / ambient light sensor. See: enable_light().
  • Enable/disable ambient light interrupt generation. See: enable_light_interrupts().
  • Enable/disable ambient light saturation interrupt generation. See: enable_light_saturation_interrupts().
  • Check whether the color / ambient light data is valid. See: is_light_data_valid().
  • Read the color / ambient light data. See: read_light().
  • Set the color / ambient light integration time. See: set_light_integration_time().
  • Set the clear light channel interrupt low/high thresholds. See: set_light_low_threshold().
  • Clear ambient light interrupt. See: clear_light_interrupt().
• Gesture detection:
  • Enable/disable gesture detection. See: enable_gesture().
  • Enable/disable gesture mode. See: enable_gesture_mode().
  • Enable/disable gesture interrupts. See: enable_gesture_interrupts().
  • Read whether there is valid gesture data available. See: is_gesture_data_valid().
  • Read the amount of gesture data available. See: read_gesture_data_level().
  • Set the threshold of amount of available gesture data. See: set_gesture_data_level_threshold().
  • Read whether the gesture data has overflown. See: has_gesture_data_overflown().
  • Read the gesture data. See: read_gesture_data().
  • Set the gesture proximity entry/exit thresholds. See: set_gesture_proximity_entry_threshold().
  • Set the gesture offsets. See: set_gesture_offsets().

The device

The APDS-9960 device features advanced gesture detection, proximity detection, digital ambient light sense (ALS) and color sense (RGBC).

The communication is done through an I2C bidirectional bus.

Datasheet:

• APDS9960

Usage examples (see also examples folder)

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

Please find additional examples in this repository: apds9960-examples

Read proximity

extern crate linux_embedded_hal as hal;
#[macro_use]
extern crate nb;
extern crate apds9960;

use hal::I2cdev;
use apds9960::Apds9960;

let dev = I2cdev::new("/dev/i2c-1").unwrap();
let mut sensor = Apds9960::new(dev);
sensor.enable().unwrap();
sensor.enable_proximity().unwrap();
loop {
    let prox = block!(sensor.read_proximity()).unwrap();
    println!("Proximity: {}", prox);
}

Read color / ambient light data

extern crate linux_embedded_hal as hal;
#[macro_use]
extern crate nb;
extern crate apds9960;

use hal::I2cdev;
use apds9960::Apds9960;

let dev = I2cdev::new("/dev/i2c-1").unwrap();
let mut sensor = Apds9960::new(dev);
sensor.enable().unwrap();
sensor.enable_light().unwrap();
loop {
    let data = block!(sensor.read_light()).unwrap();
    println!(
        "Clear: {}, Red: {}, Green: {}, Blue: {}",
        data.clear,
        data.red,
        data.green,
        data.blue
    );
}

Read gesture data

extern crate linux_embedded_hal as hal;
#[macro_use]
extern crate nb;
extern crate apds9960;

use hal::I2cdev;
use apds9960::Apds9960;

let dev = I2cdev::new("/dev/i2c-1").unwrap();
let mut sensor = Apds9960::new(dev);
sensor.enable().unwrap();
sensor.enable_gesture().unwrap();
sensor.enable_gesture_mode().unwrap();
let mut data = [0; 6*4]; // 6 datasets
loop {
    block!(sensor.read_gesture_data(&mut data)).unwrap();
    // interpret gesture data...
}
