2x 64x32 panels flipped #245

Hi,

I have 2 64x32 panels, which seems to be working, however, the image is not shown correctly, i'm sure i am missing an cli argument somewhere, but i cant figure it out, hopefully someone here can help me. Its looks to me like the "U" arrangement of the panels is the wrong way around, but i have the boards wired up correctly from what i can see.

Board: Raspberry Pi Zero Command: sudo ./demo -L --led-rows=32 --led-chain=4 -D0

Many thanks for a great project :)

Picture below is the D0 example. nbb9f7p

Why don't you just fold the panels the other way around ?

(You find some description for the -L command here: https://github.com/hzeller/rpi-rgb-led-matrix/tree/master/examples-api-use#remapping-coordinates )
