Charlieplexing 7 segment displays using Atmel Tiny26 microcontroller

Charlieplexing of discrete leds has been the topic of a few other instructables. The Charlieplexing LEDs- The theory and the How to drive a lot of LEDs from a few microcontroller pins comes to mind. They are both excellent and should be read by anyone that wants to gain a deeper knowledge of how charlieplexing really works. Charlieplexing 7-segment displays is more or less the same as doing it with discrete ...
