The PCA9633 Demo Board demonstrates the Philips PCA9633 Fast Mode Plus 4-bit I²C
LED Dimmer IC. Four LEDs are connected to the PCA9633 and through individual
pulse width modulation (PWM) of each LED show different levels of intensity.
To use, push SW8 to the ON position. The LEDs will immediately flash and glow. To
select a different mode of operation, press the MODE button (PB1). The LED will flash
amber a number of times to denote which mode was entered. Use the other 3 buttons
(SELECT, PLUS, & MINUS) to change the settings. Six different modes of operation
are provided and described below.
If the battery is low, the red LED will flash every 3 seconds.
Mode 1: Auto Demonstration Mode
Mode 2: Color Wash Mode
Mode 3: Random Color Mode
