Re: Missing characters from serial input when using DMD2

I made some progress on this... The timing device I'm using is fixed at 9600bps. Since the sketch was taking a long time in the interrupt to update the DMDs, I thought I could use two Arduinos, one to receive the serial data from the timing device at 9600bps, and then send it to the other Arduino co...

Re: Missing characters from serial input when using DMD2

Thanks for your reply. I've read though some of the first posts on this forum section, and see there are a number of others who have tried DMD projects to display serial input, and have also had issues with missing characters. I'd hoped that using the faster Arduino Due would have made this viable, ...

Missing characters from serial input when using DMD2

Last year, I used 32x16 panels in a 2w x 1h (64x16) configuration with an Arduino Mega for a simple project to display the score at football matches, which worked well. Now I’ve been working on a more ambitious project! I’m trying to build a sports timing clock in a 5w x 2h configuration (160x32 pix...

Arduino Due for large display

I've build a 64x16 display in a 2x1 DMD arrangement, using an Arduino Mega and the DMD2 library. I'm looking to build a bigger display, at least 4x2 DMDs (128x32) but ideally 5x4 (160x64). However, I've read the various threads about the Arduinos not being able to handle that many panels. Has anyone...

Re: Curtain Style DMD capability

There's a few posts about 32px height fonts, have a look here for details how to generate
