History

Keith Packard 0b90fd5adf samples, tests, boards: Switch main return type from void to int As both C and C++ standards require applications running under an OS to return 'int', adapt that for Zephyr to align with those standard. This also eliminates errors when building with clang when not using -ffreestanding, and reduces the need for compiler flags to silence warnings for both clang and gcc. Most of these changes were automated using coccinelle with the following script: @@ @@ - void + int main(...) { ... - return; + return 0; ... } Approximately 40 files had to be edited by hand as coccinelle was unable to fix them.

APDS9960 RGB, Ambient Light, Gesture Sensor
###########################################

Overview
********

This sample application demonstrates how to use the APDS9960 sensor to get
ambient light, RGB, and proximity (or gesture) data.  This sample checks the
sensor in polling mode (without an interrupt trigger).

Building and Running
********************

This sample application uses an APDS9960 sensor connected to a board
(for example as shown in this
`Sparkfun APDS9960 tutorial`_).
