adafruit 32x32 rgb matrix error

by KAMSng on Mon Apr 26, 2021 5:14 am

I made up a circuit with arduino mega,5v 3a smps, and adafruit 32x32 rgb matrix. then put a example code but It doesn’t print correctly. I checked connections several times and I attempted to change the version of liabrary but it doesn’t work. It must be print "adafruit 32x32 rgb" but it print akward character. It looks similar to correct character but it does not come out exactly.

How are you connecting the RGB matrix to the Mega?

Are you using jumper wires? If so, that approach very often does not work do to the general complexity of the setup and high likely hood for incorrect or bad wiring:

We recommend using a shield:

I considered shield but It's availabe on arduino UNO, Can I use it on arduino mega 2560?
The manual said mega need additional wiring but I can't find detail explanation.
