“Chipiplexing” efficiently drives multiple LEDs using few microcontroller ports
by Guillermo Jaquenod @ edn.com Actual microcontrollers have powerful bidirectional I/O ports, and you can use different techniques to fully exploit such capabilities. Recent Design Ideas described the “Charlieplexing” method as an effective way to drive M=N×(N–1) LEDs using...
