Hello,

can somebody help me with this?

what are the parameters you give on the commandline?

lu93pi commented 5 years ago

-D0 --led-gpio-mapping=adafruit-hat --led-rows=16 --led-cols=32 thats all

hzeller commented 5 years ago

if it is an outdoor panel, you might also need to play with the minute multiplexing options

lu93pi commented 5 years ago

tried all multiplexing options .. 0-9 .. the top half of the display is still green

lu93pi commented 5 years ago

tried another pi.. with the --led-rows=16 command the 4. 8. and 12. row dont work and still top half green
