    Embedded Lab An online teaching laboratory for Microcontrollers and Embedded Systems Home Products Theory PIC Experiments PIC Projects Tips Tricks dsPIC chipKIT Netduino Contact Introducing a new serial SPI 8-digit seven segment LED display module using MAX7219 R-B Dec 29th , 2012 Seven segment LED displays are brighter , more attractive and provide a far viewing distance as well as a wider viewing angle as compared to LCD displays . The major drawback of using seven segment LEDs is they are resource-hungry . Time-division multiplexing is the most common technique of interfacing 7-segment LEDs to microcontrollers . With this technique , an 8-digit seven segment LED display with the decimal point requires at list 16 I O pins of the microcontroller , which is quite a lot . Consequently ,
