After designing this single chip Charlieplexed 24 hour Clock/Calendar/
Hi Guys,
After designing this single chip Charlieplexed 24 hour Clock/Calendar/Timer well over a year ago, I finally found some time to prototype it and it seems to work pretty well.
**broken link removed**
The Charlieplexed display uses direct I/O drive on the segment lines and this limits 'peak' and 'average' current and display brightness....
