Duplicated rows on RGB Matrix 32x32

Post by masonkyi »

Hi,

I am attempting to recreate a project done using the 32x32 led matrix and arduino mega 2560.
Currently, I am seeing in the example code duplicated pixels in both example code and by single pixel input.

My code only runs this line
matrix.drawPixel(0,0, matrix.Color333(7, 7, 7));
which should output one white pixel in (0,0) however a second white pixel appears at (0, 8).

I have changed all the wirings twice.

Can someone assist please?

No idea what code you use, what wiring and what platform (Arduino/Pyhton).
I prefer Protomatter on the Arduino IDE for driving these matrices, as it allows good setup of pins, no of address lines, bit depth and buffer use.
