| == RPI Software Setup SDK ==
| | https://w2.electrodragon.com/gollum/search?q=MPC1073-test-log-dat.md |
| === Main Github ===
| |
| * Please ask for software support via github
| |
| * clone project https://github.com/hzeller/rpi-rgb-led-matrix/tree/master/adapter
| |
| * build the binary executable file, and use following commands
| |
| make -C examples-api-use
| |
| | |
| * https://github.com/hzeller/rpi-rgb-led-matrix
| |
| === Prerequisite Checklist ===
| |
| double check for GPIOs
| |
| * turn off => SPI IIC, 1-wire, serial, etc in raspi-config
| |
| * turn off => sound in /boot/config.txt -> add line dtparam=audio=off
| |
| * optionally remove following modules: sudo apt-get remove bluez bluez-firmware pi-bluetooth triggerhappy pigpio
| |
| * optionally disable: audio in kernel
| |
| cat <<EOF | sudo tee /etc/modprobe.d/blacklist-rgb-matrix.conf
| |
| blacklist snd_bcm2835
| |
| EOF
| |
| | |
| sudo update-initramfs -u
| |
| * by following up setup, the GPIO output should be all good
| |
| | |
| == Quick Start Guide ==
| |
| === 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
| |

| == FAQs ==
| |
| * Using all 3 chains with rPi 4, is there any GPIO free to use?
| |
| No any free pins left except SC / SD pins
| |
| | |
| * What are SC and SD pin holes?
| |
| GPIO0 = SDA0, GPIO7 = SCL0
| |
| | |
| * What are RX pin hole?
| |
| GPIO15, ROW_E pin, can be set to ground
