This is a 16C57 with some transistors, driving 8 digits worth of multiplexed LED display, with the intent of serving as a generic "serial LED" display, or for any smallish clock-like circuit. Should be at: http://www.geocities.com/westfw/electronics/pic-display.zip (This is an Eagle schematic and board file, all zipped up.) I'm interested in suggestions of all sorts, from "you really need some reset circuitry" to "the patterns the traces make are ugly" and/or "don't you think it would have been smarter to start with a standard sized board of some sort instead of picking random dimensions?" Thanks Bill W (yeah, I know 16c57s are dinosaurs. But between Ebay and piclist, I now have quite a lot of them to do SOMETHING with. Other suggestions are welcome, too...) -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
