Platform-agnostic Rust driver for the APDS9960 digital proximity, ambient light, RGB and gesture sensor.

Rust APDS9960 Digital Proximity, Ambient Light, RGB and Gesture Sensor Driver

This is a platform agnostic Rust driver for the APDS9960 digital proximity, ambient light, RGB and gesture sensor using 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 example

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

extern crate embedded_hal;
extern crate linux_embedded_hal;
#[macro_use]
extern crate nb;
extern crate apds9960;

use apds9960::Apds9960;
use linux_embedded_hal::I2cdev;

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