Strange pattern displayed and not lighting the right pixels #10

Hi,

I'm using an Adafruit RGB Hat which works perfectly with your library. However I wanted the matrix to be driven over the network and thus turned to this project. I recompiled the matrix lib using the proper DEFINES for the Adafruit Hat and ran the examples without problem. I then got back to the root of the project, ran make and launched. I'm using 2 32x64 led panels chained together (so I used -r32 -c4 as for your samples in matrix library). What I see on the panels is 2 big blue squares at the top and one rainbow bar in the middle of the screen so that it's just like a squared smiley. It seems to properly broadcast on the wlan as it's recognized by LED iOS app and the Processing samples. However when sending pixels, almost nothing changes on the panels: some pixels light, ghost repeating the smiley pattern but a few pixels below and with a lower intensity.

There is something wrong but I have no clue left :) Any help will be much appreciated!

best regards,

found my error. I simply didn't recompile the pixel-push class after updating DEFINES in matrix/lib folder. After a make clean and make works like a charm. I also recommend making the PWM patch on Adafruit's board: it's much better!
