Serial seven segment LED display shield for chipKIT
Posted 2018-01-06 11:35:37 by MajenkoSeven segment LED displays are brighter, more attractive, and provide a far viewing distance as well as a wider viewing angle compared to LCD displays. This project describes a serial seven segment LED display shield for chipKIT Uno32 or compatible boards. The shield consists of eight 0.56″ seven segment displays that are driven by one MAX7219 chip. The shield also features a light dependent resistor (LDR) to implement adaptive brightness control to the LED displays. The chipKIT Uno32 board can sense the surrounding illumination level by reading the LDR output through A0 or A1 analog input channel, and use that information to adjust the brightness of the LED displays. A demo code and Eagle CAD files are also provided.
