[Tim]’s Dice10 is an exercise in minimalism. Building an electronic dice using an ATtiny10 with code that fits within 1kB is not too difficult. Charlieplexing the LED’s would have used three of the ...

[sixerdoodle] sent us this nice firefly project that serves as an intro to charlieplexing. We’ve mentioned charlieplexing before, in our LED Life post and the Breath Controlled LED candles post. This ...

The term “Charileplexing” is not a familiar one for many electronics hobbyists. Charlieplexing is a technique proposed in early 1995 by Charlie Allen (at Maxim Integrated) for driving a multiplexed ...

A few articles have recently appeared describing novel ways to increase the number of LEDs a microprocessor can drive with a limited number of pins (Reference 1). The standard multiplexing technique ...

Charlieplexing. The verb is an electronics technique apparently named after one Charlie Allen, an engineer at Maxim. It involves minimising the use of I/O pins on a microcontroller to drive a maximum ...
