Zu viele LED anzusteuern und zu wenige Ausgänge am Controller übrig?
#Charlieplexing kann eine Lösung sein
test printing a 3x3 #charlieplexing circuit, will probably pack this tighter if there's partial success.
2 days of learning charlieplexing and PIO on the rp2040 only for it to just not work and have no real indication as to why. Best guess is that maybe the LEDs aren’t all the same. I guess tomorrow I’m playing around with that PIO emulator - and therefore once again installing the JDK 😫
Also I suspect that my PIO program isn’t very good. No idea what would improve it though! #rp2040 #pico #charlieplexing #LEDs #pio

Work in progress on ESP8266 binary clock... Just connected hours for now (19 in binary). Need to solder 13 LED cables tomorrow to connect them all. #esp8266 #binary #clock #charlieplexing #ntp https://hackaday.io/project/169420-another-city-clock

I'm working on a binary clock based on an esp8266, to sync time via ntp at boot. POC, including charlieplexing, validated https://github.com/paulgreg/City-Clock #esp8266 #ntp #charlieplexing
