Try using a lower baud rate, I think the line or the clock is noisy so transmissions at high bauds get garbled.

how are you sending the serial data to the displays? Are you using ‘Processing’ or something? Thanks for the help!

I’m sure that would be doable, though obviously you’d need completely different code. You could send the visual data over the serial port and then display it on the matrix, but the monome project uses buttons as well which aren’t on the matrix.

I used the 10pin ICSP header in the middle of the board with my USBtinyISP. Going through the FT232RL didn’t work out so well, although that was my original plan. The ICSP method is faster anyway.

thanks. how did you program your atmel chip? through the ftd232 on the board you made? I have a USBTINYISP programmer.

Sure thing, source code is at http://randomskk.net/projects/led_matrix/rev06/led_matrix.cpp and http://randomskk.net/projects/led_matrix/rev06/font.h

Hi Random. Would you by any chance be able to share your code? Mine is doing funky things and I’m getting frustrated haha. Thanks
