ViSi-Genie Magic: Color Picker
Introduction
This example shows how to use Keyboard + ColorPicker Event Magic to read values from the Color Picker object and then manipulate the values to be able to display the color picked to an RGB Led. The program used bit operations and bit manipulations to convert RGB(565) value from the color picker input to RGB 24 bit format. After conversion, the values are mapped to 0-1000 for PWM.
