High Resolution RGB LED Color Mixing
This application note demonstrates color mixing using the PIC12F1572 MCU. The PIC12F1572 microcontroller features three 16-bit pulse-width modulators (PWMs), which allow precise control over each RGB LED, allowing smooth transitions even at low-brightness/luminosity levels.
Development efforts are supported by the following features of this demonstration board.
• ICSP™ programming connector
• EUSART bus tie-in points
• USB or battery powered
• Multiple test points
A color mixing software routine allows developers to specify colors in xyY format with the PIC® device performing color mixing calculations.
