led matrix 32x32 displays partial images

Post by totogno »

Hi
I bough a led matrix 32x32 from Adafruit, model with a single 16 pin header for input, with label (from top left to right): R0,G0, B0,' ', R1,G1, B1,' ' , A,B, C,D, CLK,STB, OE,' '.
(' ' means there isn't written anything)

I tried with hzeller code
https://github.com/hzeller/rpi-rgb-led-matrix

the panel shows only half of the meant image: first 8 rows are off, second 8 rows show top quarter of the image, third 8 rows are off and fourth 8 rows show second quarter of the image.
See attached the image displayed

Does anybody know what can I do to see the full image?

Thanks in advance

Could you post clear pictures of your board and the connections to it? Have you modified the code at all or are you running it exactly as published?
