This sample controls up to 12 LEDs connected to a LP503x driver.
First, for each LED information is retrieved using the led_get_info
syscall and printed in the log messages. Next, from an infinite loop, a
test pattern (described below) is applied to all the LEDs simultaneously
(using the led_write_channels syscall) and then to each LED one by one
(using the led_set_{brightness,color} syscalls).
Test pattern:
For each color in red green blue white yellow purple cyan orange:
- set the color
- turn on
- turn off
- set the brightness gradually to the maximum level
- turn off
