 Hey guys, this is Parker Domen, the Longhorn Engineer, and I just finished the 16x16 LED Matrix test using the FPGA. The propeller was not fast enough to push the old bits necessary for the whole dot matrix display, which will be 16x96 bits, but the FPGA is plenty fast to be able to push that refresh rate. I actually had to slow down the refresh rate because it was going so fast that these transistor arrays were not working correctly because it was switching too fast. So I have some, let's see if I can, some verilog code that one of my friends, Marshall, helped me write. You'll be able to find the code in the description of the video. So I'm gonna do something, go ahead and just program this to open the programmer and start. That should make a nice display. You might see a little flickering due to the refresh rate of the camera, but there is no flickering in the, in real life. So yeah, so it displays an XOR pattern and basically just proves that it's actually doing the matrix, matrix scene correctly. Yeah, it actually works really nice. Basically, see how this FPGA has more banks of IO. And so all these other banks reconnected to the older columns so that you can control a 96x16 display. Oh, and powering it is my, you know, power supply that's over there. So it works pretty good. It's much, much faster than the propeller in terms of matrixing. I mean, when it was running straight off the 50 megahertz clock, which is right here, it was actually refreshing the display at over three megahertz, which is way too fast, apparently for these chips. I actually don't know how fast it's updated. Now it's probably about two kilohertz, which, you know, as long as you're above 60 Hertz, it's fine. But yeah, looks pretty good. So I'm gonna probably work a bit more on the code and get a better demo of the of the display. And the propeller that controls the main part of the code is actually going to seriously feed in the data that will be displayed on this screen. And so I've got to work on that code and make sure all that works before I order the PCB for the whole dot matrix display. Well, so next time, guys.
