Installation on a Raspberry Pi

1. Raspbian

• Flash SD Card

2. Update apt-get

• sudo apt-get update

3. Install Node

4. wget http://nodejs.org/dist/v0.10.16/node-v0.10.16-linux-arm-pi.tar.gz

5. tar xzvf node-v0.10.16-linux-arm-pi.tar.gz

6. sudo mv node-v0.10.16-linux-arm-pi /opt/node

7. node -v (to make sure the version is 0.10.16)

8. Install Aurora

9. git clone https://github.com/gregfriedland/AuroraV5.git

10. cd AuroraV5

11. npm install

12. Install Aurora to start when the system boots

• Serial version
  1. sudo cp AuroraV5/system/aurora-serial-init.d /etc/init.d/aurora-serial
  2. sudo chmod 755 /etc/init.d/aurora-serial
  3. sudo update-rc.d aurora-serial defaults
• Fadecandy version
  1. cp AuroraV5/system/aurora-fc-init.d /etc/init.d/aurora-fc
  2. chmod 755 /etc/init.d/aurora-fc
  3. cp AuroraV5/system/fcserver-init.d /etc/init.d/fcserver
  4. chmod 755 /etc/init.d/fcserver

6. Setup Raspberry Pi Camera V4L2 driver (so )

7. Follow instructions here

8. Reboot

9. Optional for Rasperry Pi

10. Comment out this line in node_modules/serialport/serialport.js which is slowing things down: //debug('Write: '+JSON.stringify(buffer));

Notes

1. To get it running on two side by side SmartMatrix panels for 64x32, I used the rgb48 branch of my SmartMatrix fork and overclocked the Teensy 3.1 to 144Mhz.

Work in progress

1. Trigger program with opencv face detection
2. Get color speed working
