Tomasz Bursztyka e18fcbba5a device: Const-ify all device driver instance pointers Now that device_api attribute is unmodified at runtime, as well as all the other attributes, it is possible to switch all device driver instance to be constant. A coccinelle rule is used for this: @r_const_dev_1 disable optional_qualifier @ @@ -struct device * +const struct device * @r_const_dev_2 disable optional_qualifier @ @@ -struct device * const +const struct device * Fixes #27399 Signed-off-by: Tomasz Bursztyka <tomasz.bursztyka@linux.intel.com>		2020-09-02 13:48:13 +02:00

PCA9633: 4-Channel RGB
######################

Overview
********

This sample controls 4 LEDs connected to a PCA9633 driver, using the
following pattern:

 1. turn on LEDs
 2. turn off LEDs
 3. set the brightness to 50%
 4. turn off LEDs
 5. blink the LEDs
 6. turn off LEDs

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

Build the application for the :ref:`stm32373c_eval_board` board, and connect
a PCA9633 LED driver on the bus I2C-1 at the address 0x62.
