Hi guys,
Any idea how to fix the pattern here. the text is 1234, which is clearly not in the correct order..

I'm using the P8 1/4 16x32 from china with 24 shift registers

1234 --  is sliced horizontally, the bottom half and the top are swabbed...


im using RUUD RGBmatrixPanel but still have problem with my LED P10 RGB 1/4 scan outdoor.

the problem is row position not correct (photo attach), its should be rows :

5 6 7 8 1 2 3 4 13 14 15 16 9 10 11 12

code + library running perfectly with my RGB indoor.

any one can help me to solve this problem?, need advice/suggest to edit RGBmatrixPanel.cpp.



done, finally i solved the problem ^^

Have the same problem with rows, they are in order like this :

5 6 7 8 1 2 3 4 13 14 15 16 9 10 11 12

Its solved with changing 1 line in Ruud library


Thanks a lot,
I try to find the line to modify.
For the moment i try to change nmultiplexrows,shift,y,buffersize... i have some change but not in good way.
may be i change the wrong value.
Have another tips?
Thanks in advance.
