Have a look through the great race code and modify the track data to suit your text. (The great race just scrolls a table of data - so putting text in there will scroll the text)

i don't know how to modify it..sorry!

thank you!

First see if you can get the game working, then we can help you modify it to show your text.

Here's a link to the schematic:

And here is the source code:

The picture you posted lines up exactly with the schematic. Put those two pictures next to each other on your computer screen and compare them. Have a look at where each connection goes and you will see they are the same.

The only extra thing you need to add is the one extra wire on pin 2 of the microcontroller to the red cathodes on the led matrix (which should be the red dot in the bottom right corner on bitfogavs drawing.)

I just finished a prototype of the great race for a school project but for some reason column 5 and 7 switched places so all the data that is supposed to be on column 7 is on column 5 and vice versa. This project is due soon can you please point out all possible causes for this to happen?

Thanks

What if you swap the connections over from column 5 to 7?

I guess i can try that, could there be any other source for this problem?

Thanks

Unfortunately it's very hard for us to know the fault without seeing the physical circuit. But it happens to the best of us whereby we get connections around the wrong way. Give that a try in the first instance and if it's still no good we shall see where we can get to from there.

I guess ill have to make a more thorough check because from a quick look i took that did not seem to be the problem

Thanks again
