Hi to all,

I found this on other forum and I try it to simulate. I think it is a mistake in the way I connect that bunch of led, but I cannot find it. I'll ask nicely for somebody which has Proteus to have a look on that file and tell me or better make the necesary modification to make it work.

Many thanks in advance
Gabi

You need the hex file so Proteus can run. try building with a few leds, and add more as you get it working.

You have shorts on top row of leds, so none of your leds will light.
you may also have a problem with your code.

Top row and right side every led is shorted A to K
after removing shorts 4 leds light and no clock from port B or port C.
no looked at your code.

Hi,

Many thanks. in the end of the day I was able to do that myself..., but it still not working. Maybe you have time to look at the file which drove the pic.

Thanks anyway
