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

| - https://www.adafruit.com/product/2343 |
| |
| 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 |
