RGB and Gesture Sensor

Overview
|
|
********
|
|
|
|
This sample utilizes APDS-9960 Sensor and reads RGB values from the sensor
|
|
then displays the color through the APA102C LED.
|
|
|
|
|
|
.. note::
|
|
This sample does not use the Zephyr sensor APIs
|

|
The SparkFun RGB and Gesture Sensor was being used:
|
|

|
|
|
|
For APA102C, on the sensor subsystem (ARC) side of Arduino 101:
|
|
|
|
1. GPIO_SS_2 is on AD0 (for APA102C data)
|
|
2. GPIO_SS_3 is on AD1 (for APA102C clock)
|
|
|
|
The GPIO driver is being used for bit-banging to control the APA102C LED.
|
|
|
|
The APA102/C requires 5V data and clock signals, so logic level shifter
|
|
(preferred) or pull-up resistors are needed. Make sure the pins are 5V
|
|
tolerant if using pull-up resistors.
|
|
|
|
.. important::
|
|
|
|
The APA102C are very bright even at low settings. Protect your eyes
|
|
and do not look directly into those LEDs.

Building and Running
|
|
********************
|
|
|
|
This sample can be built for multiple boards, in this example we will build it
|
|
for the Arduino 101 board:
|
|
|
|
.. code-block:: console
|
|
|
|
$ cd samples/sensors/apds9960
|
|
$ make BOARD=arduino_101_sss
|
|
$ make BOARD=arduino_101_sss flash # with JTAG
|
|
.. or
|
|
$ dfu-util -a sensor_core -D outdir/arduino_101_sss/zephyr.bin # with DFU
