I have datasheet info from panel supplier for my P4 outdoor LED panel. Constant current 1/8 scan Driver chip: ICN2037 Decoding chip: 7258 No E-Line
sudo ./demo -D0 --led-gpio-mapping=adafruit-hat --led-rows=32 --led-cols=32 --led-chain=2 --led-multiplexing=6
sudo ./demo -D3 --led-gpio-mapping=adafruit-hat --led-rows=32 --led-cols=32 --led-chain=2 --led-multiplexing=6
Hi everyone. I try a lot of combinations with only one result you can see above. Lower half part is not addressing. Any ideas how to working with these type of panel? I know it is construct from 2-sub-panels, there for -led-chain=2. It is problem in driver chip ICN2037? New one in this library and it is difficult to drive the panel? I bought theme in 8/2019. I am working on a project and I have right now a big STOP with these panels :(
--led-inverse
It seems to be working - the whole LED panel area :)
Thank's for any help. I am reading tons of other forums and issues here with no result what to do.

I had old source code. After git pull the "64x32 1/8 scan panel" it work for me. For me works: --led-multiplexing=6
I have problem to display lower part of LED P4 outdoor panels (64X32 Pixels, 1R1PG1GB SMD 1921, 1/8 scan, refresh frequency >=400Hz, www.led-card.com) with my AdafruitHAT and RPI 3B+. I have for the test purpose in a chain two pannels only.
This working well in upper half of display (scrolling ppm): sudo ./demo -D1 --led-gpio-mapping=adafruit-hat --led-rows=32 --led-chain=4 --led-multiplexing=6 runtext16.ppm![20191017_174644_cut](https://user-images.githubusercontent.com/56689303/67026121-79ada900-f107-11e9-9c83-dff96859e24e.jpg)
For runtext.ppm is not working. sudo ./demo -D0 --led-gpio-mapping=adafruit-hat --led-rows=32 --led-chain=2 --led-multiplexing=6 runtext.ppm![20191017_175534_cut](https://user-images.githubusercontent.com/56689303/67026154-89c58880-f107-11e9-991f-d2918c5cbaa4.jpg)

I try E-link (pin connections to 8 or 16) without any change. I try resolderin pins on AdafruitHAT, all seems to be fine.
