Yeah...pretty much the same code as before but for 4 chips and with the first chip as master sync, the other 3 as slaves...I didn't blank the changeover to the next six frames to show how fast it is.

So...frame data is just 6 frames all LEDs on...and 6 sets of PWM data for each animation.  8)

I've written a program which takes 6 frames of an animated gif and converts them to the data required for the 24x22 screen...I separate the frames in photoshop first then feed them to the C++ prog, then copy and paste to the MCU datafile.

I'm interested in what you want to do with this project as well...perhaps we can come up with something together....

We will, I just need to fiddle this winter break.  I have so much to do though, so it might be here and there.  I need to reinvent something and then make an entire website and program as well as work at the bakery.

No pressure...after all this is a hobby.  :smiley-mr-green:

I've got a few things to do myself but will continue with this project. I'd like to find some RGB LEDs that I can solder in a tight, even matrix then run with AS1130s...this chip would be perfect for colour mixing and I have ideas for full motion video if I can bulid a suitable screen.

True,

If you get the itch to use SMD RGB 5050 LEDs, I found a vendor in china on eBay who sells them at really cheap (100 for $8).  Those are pretty small so they can go into tight spaces

It'd be good if you could let me have the details...only problem is that I would have to have a board made for them and hand soldering 528 5050 LEDs does not fill me with joy... :smiley-mr-green: :smiley-mr-green:

Do you have a good manufacturer who would produce the board with the LEDs already soldered? Maybe we could look at that option...
