Drive Notice
- The panels of the same size could have different drive (scan) methods, it depends on the panel's driver chip.
- please try different led-multiplexing, from 0~17
--led-multiplexing=0
P8 P10 Outdoor 32x16 (tested)
Run example for our selling 32x16 panel
- P10 - 32x16
./examples-api-use/demo -D 0 --led-cols=32 --led-rows=16 --led-multiplexing=8
./examples-api-use/demo -D 0 --led-cols=32 --led-rows=16 --led-multiplexing=3 ./examples-api-use/runtext16.ppm -D 0 --led-cols=32 --led-rows=16 --led-multiplexing=8 ./examples-api-use/demo -D 0 --led-cols=32 --led-rows=32 --led-multiplexing=1
- To chain other panel:
--led-chain=2 to --led-chain=4
- Other example will have the same configuration
--led-rows=8 --led-chain=2
32x32
- multiplexing =1
./examples-api-use/demo -D 0 --led-cols=32 --led-rows=32 --led-multiplexing=1
P4 64x32 (tested)
- multiplexing=0
./examples-api-use/demo -D 0 --led-cols=64 --led-rows=32 --led-multiplexing=0
- Tested panel is 64x32 P4-256x128-2121-A1
P3/P4 64x64 (tested)
Extra Setup Needed
- Setup P4 jumper to ground, P8 jumper to #E line
- multiplexing usually 0 or 1, try further options only when you have special board
CMD for both P3/P4
- ./examples-api-use/demo -D 0 --led-cols=64 --led-rows=64 --led-multiplexing=1
128x128 / 256x128
- Should be not supported
