Dot matrix GUI interface through serial

Hi, I’m a first time poster on the form but i have received a lot of help from all on this form since I started with micro controllers.

My question is whether there is a GUI interface to quickly program an image or selected bits on a LED matrix or LED cube. I’ve been struggling to fin a simple piece of freeware that would allow met to interface from a PC.

I’m considering writing my own program to to this but it would be of great help if there is an example to work from.

Yes, there are free programs to do this, and they are easy to find on Google. They output HEX codes as well as binary for code that will set rows or bitshift magical things. The programs themselves may not output directly, you would have to set up handling of that data if you are trying to send from pc.

What are the dimensions of your matrix?
