#146855 - frustration Responding to: ???'s previous message |
I can understand your frustration - the web is full of contradictory and often straight wrong advices regarding this topic...
Search this forum, and focus on the "dot matrix gospel" of Erik Malund: NO MULTIPLEX (especially for newbies with only 2 weeks at hand). Then, it reduces into simple "how to drive 64 LEDs" question, for which Erik has the simple answer - use the integrated shift-latch-current source ICs. Of course, this also excludes using of ready-made 8x8 or 5x7 "bricks", and you have to use discrete LEDs. JW PS: [slightly later] - what a great example this very thread - only 2 answers, and the Great Question of LED Displays (to be multiplexed or not to be multiplexed) is already here... |
