devsar devsar / Mbed 2 deprecated SparkFun_APDS9960_Sample

Sample Test Program for SparkFun APDS9960 Library. Currently only tested with HRM1017.

Dependencies:   SparkFun_APDS9960 mbed

Fork of SparkFun_APDS9960_Sample by devsar devsar

Sample Program for APDS9960 library using HRM1017. Tested Pin Connection:

APDS9960 <=======> HRM1017

  • VL (Not Connected)
  • GND <=======> GND (0V)
  • VCC <=======> VDD (3.3V)
  • SDA <=======> P0_22 (sda I2C0)
  • SCL <=======> P0_20 (scl I2C0)
  • INT <=======> P0_2

Gesture result is printed out using Serial (PC).

PS: Currently planning to use HRM1017 BLE to send the result to smartphone.
