Proteus fast delay scanning problems 8x8 led
Is the program too fast for Proteus software to handle this?


No, the software can handle that sort of thing. I have done the same with a transistor for each seven segment display. If I have two seven segments, when one is off the other is on and vice versa. This is all done at a  very fast rate which cannot be detected by the naked eye, and Proteus handled this well.

Could there be something from your code which is not working?
