    Pixel Grid converted to APA102 style RGB strip

    This is a 64 * 32 RGB LED display I have used. They are 320 * 160mm and priced at AU $50 from ebay. I do not think a picaxe will drive these displays, I used a PIC32MX470 to drive it. Bill

    This is the schematic I used in my magic switchboard, The secret of the operation without batteries is the addition of a super cap of 1F. The program is for a 14m2 but can modified for the 18m2 by reassigning the IO. #picaxe 14m2 ' Magic Switchboard - original source by "Technical"...
