Add a sample application to show the LP5562 driver. The three RGB channels are used to set multiple colors after each other under the assumption that accordingly colored LEDs are connected. Blinking is also shown in multiple colors. Signed-off-by: Johannes Hutter <johannes@proglove.de>

Overview
|
|
********
|
|
|
|
This sample controls 4 LEDs connected to a TI LP5562 driver, using the
|
|
following pattern:
|
|
|
|
1. turn on LEDs to be red
|
|
2. turn on LEDs to be green
|
|
3. turn on LEDs to be blue
|
|
4. turn on LEDs to be white
|
|
5. turn on LEDs to be yellow
|
|
6. turn on LEDs to be purple
|
|
7. turn on LEDs to be cyan
|
|
8. turn on LEDs to be orange
|
|
9. turn off LEDs
|
|
10. blink the LEDs in white
|
|
11. turn off LEDs
|
|
12. blink the LEDs in purple
|
|
13. turn off LEDs
|
