Angry Badger Member May 15, 2009 #2 Hi, Not sure what you mean by 'rasta scan'. That's something to do with crt's isn't it? Do you simply want to drive some 7 seg displays from a single port on you 16f690? I've attached some sample code I used ages ago. Maybe it will be some help. The 7 seg digits are common cathode by the way. Attachments Multiplexed 7 seg.asm 4.1 KB · Views: 378 PICcct 001.jpg 678.3 KB · Views: 676 Last edited: May 15, 2009
