• Run example for our selling 32x16 panel:

./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
