Display a static image on a dot matrix

Hello everyone,

I am working on a project to create a slot machine for a systems project and I am unable to display the image correctly. I am able to have the images scroll though, but it will not display my specified image. Any help?

Hi and welcome to the forum.

Good news, I can narrow down your problem to one of 3 possibilities.

  • an error in your code
  • an error in your circuit
  • both

Hope that helps. If you need something more detailed or specific, perhaps you could be more....

Please read the posting guidelines about the use of code tags, and how to use the forum.

Please feel free to provide as many details as you think necessary.
Like what the display is, schematic etc.
You know, all the usual stuff - things that you know and can see, that we don't and can't.

Don't apologize - do something about it.

No, I meant about using code tags.

Also, your code is incomplete.

There are three if statements, one commented out.

I have been able to cycle through the six images,

Re-use that code.

To cycle through them, you must have had code to display one image after the other.
You didn't post that code, but if I were you, that's the code I'd be looking at.

Ok.
I'm probably being stupid, and misunderstanding your problem, but it seems to me that if you can display all the images, you can display just one.

I'll leave you now.

Or maybe one of us simply isn't trying hard enough.

I understand your ideology that if I can cycle through six, I should be able to display one, but its just not the case.

It's not ideology, it is simple reasoning.

First you describe a problem, but give no means for anyone to help you solve it. (None, really, re-read your first post)

Then, when someone else points this out, you report that person to moderators, whining that they're being unhelpful.

Then you post a self-confessed snippet (oh, how we hate snippets), but not the part of the code that contains the solution.

Again, you whine that you're not being helped, despite the fact that you are quite clearly in possession of the solution.

Are you seeing the problem from the other end of the telescope now?

Re: your most recent report to moderator.
Yeah, I wonder about that too.

I notice also that you deleted your most recent post. Twice.
Hmmm.

Doesn't the function refreshScreen in reply 14 do exactly what is required?

Of course, the somewhat wasteful array "pixels" (1024 bits of RAM to store 64 bits of data! :o ) has to be filled with the correct data first, but that's what setupChar does, albeit for an arbitrary string, though this would be simple to change to a single function parameter.

I too fail to see how this code is irrelevant.
