If you want to control every segment individually without multiplexing you are essentially looking at simply a large number of I/Os. The simplest OTS solution is to just chain a bunch of shift registers, one for each digit. If you want to control the current of each segment, look at the TLC5940 (16 channels) or TLC5947 (24 channels) or TLC5952 (24 channels, CC only) -p. --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
