UPDATE! I have finished a PCB for the RGB Pong Clock (or any other project using an RGB Matrix panel) and have sent it off for a quick run. It works with both the Core and the Photon and is designed to attach to the back of the panel. Once it is tested, I’ll be making it available to everyone. H…

sorry, i forgot to mention that i commented out that line in the code //#define LAT A4 because that was the first thing thought might have been it. i am already using the new shield version LAT is wired to TX. THX again.

@KWeb , if you are using the “v4” configuration then A2-A5 will be open. Nonetheless, A4 operation is still affected by the hardware time. If you modify this line in RGBMatrixPanel.cpp: refreshTimer.begin(refreshISR, 200, uSec); to: refreshTimer.begin(refreshISR, 200, uSec, TIMER7); It will use…

That did it… THX a lot… I’ll show the project when i am done :wink:

@KWeb , well shiver me timbers!!! I’m going to make that a permanent change to the library (only for the Photon of course) so that there is not interference with timer-based GPIO. Thanks for the challenge and testing the fix!

Uh, one more question: is there a way in the library to find out what color an led is set to? Like: getColorRGB(x,y); in my project i am designing a game and i draw randomly sized shapes on the matrix and move them. the easiest way to see if i had a colission would be if i could read out if i ju…

@KWeb , there is no function for that. I suggest you create your own array/buffer against which you can query color. You would memcpy your buffer to the display buffer whenever you want to update the display.

@peekay123 , Could I buy one of the shields from you? Thanks, Cole

@whackedspinach , of course! I sell them for US $30 plut $7.50 shipping.

@peekay123 , Great, how can I pay you? Also, is there anything else you would recommend picking up with the shield? I have the RGB Matrix and Photon already.

Hi, please send link on PCB DESIGN source. Thanks
