Chained LED 64x32 Matrix using Arduino for static images

Post by gineer »

So I have two 64x32 LED matrices. I have one figured out running perfectly using an Arduino Mega,

I'd like to try chaining the two to form a singe 128x32 matrix to display static text without any animation (assuming it's the animation bit that blows the Arduino Mega's RAM budget?

Has anyone made any progress on making this work? My second option is to run two Arduino Mega's, one for each matrix and then interfacing them using serial or I2C. As I mentioned I want to display static text or possibly a static image without any animation.

updating the width in the initiation code from 64 to 128 (pure assumption) just confuses the displays. Setting it back to 64 works, but this simply duplicates the two screens (with some anomalies on the second screen). There doesn't seem to be a panel count anywhere in the Arduino code like what I've seen for the Pi code.

Is this possible, or would I have to learn how to use Linux and get a Pi?

please help~

Sorry, but the library doesn't support chaining matrices.
