OSC is aready implemented on PocketVJ 3.6 or newer
Check CP in upper right hand corner of web CP.
Next we will login and control the PocketVJ (PVJ) using SSH
On a Mac open up Terminal
Type ssh [email protected] (Your IP address will may be different, use AngryIP Scanner or Login to your network Router to discover the PocketVJ IP Address)
You will be prompted for a password; enter `pocketusr`
Now we will install node js. This is for Raspberry Pi 3, I used name -a to reveal a armv7l core.
wget to download.
wget https://nodejs.org/dist/v8.11.3/node-v8.11.3-linux-armv7l.tar.xz
tar to extract the folder
tar -xf node-v8.11.3-linux-armv7l.tar.xz
cd to open the folder
cd node-v8.11.3-linux-armv7l/
use node -v to check the installed version
node -v
use npm -v to check the npm version
npm -v
if this installs correctly, then we can proceed.
Next we will install 4 packages necessary to run OSC
sudo npm install socket.io
sudo npm install node-omxplayer
sudo npm install osc-receiver
sudo npm install ip
Move all the files to the proper directory for the webCP to control
cp to copy the files to the /usr/local/ directory
sudo cp -R * /usr/local/
Now we will load the latest CP .zip file onto the internal section of the pocketVJ. You can use the web CP FTP or another FTP Client.
When the PocketVJ-CP-v3-master.zip file is in the internal directory. Got to the web CP in your browser. Goto the "Wrench Icon" on the far right tab and click "UPDATE Everything" & WAIT... Don't touch anything else until the PVJ has completely updated.
Pay attention to the CP version in the right hand corner. Then refresh the page and it should show the latest version.
Now to properly setup the Osc_control.js file, it will need to be in the right directory.
Right now it is in: cd ~/www/sync/
and we want to move it to: /home/pi/osc/
So lets make a directory called osc and move the file into it:
mkdir -p /home/pi/osc/ && sudo mv /var/www/sync/osc_control.js /home/pi/osc/
Then you can start it manually and see if your OSC commands are making it through.
If should say something similar if it is running correctly.
pi@pocketvj-100:~ $ node /home/pi/osc/osc_control.js
Running OSC
Config TouchOSC Host to 192.168.1.101 and Port(outgoing) to 9876
Troubleshooting:
If your RPi is connected via ethernet or wifi to a router with internet access, but is unable to download using wget, then you may have set a manual IP address.
check using: hostname -I
If it says something like:
pi@pocketvj-100:~# hostname -I
192.168.2.100 192.168.1.105
then type in sudo nano /etc/network/interfaces
and change static
auto lo
auto eth0
iface lo inet loopback
iface eth0 inet static
address 192.168.2.100
netmask 255.255.255.0
gateway 192.168.2.1
auto wlan0
iface wlan0 inet static
address 2.0.0.100
netmask 255.255.255.0
up iptables-restore < /etc/iptables.ipv4.nat
to dhcp
auto lo
auto eth0
iface lo inet loopback
iface eth0 inet dhcp
address 192.168.2.100
netmask 255.255.255.0
gateway 192.168.2.1
auto wlan0
iface wlan0 inet dhcp
address 2.0.0.100
netmask 255.255.255.0
up iptables-restore < /etc/iptables.ipv4.nat
hit Control+O to WriteOut, hit Enter to confirm and save.
Then hit Control+X to exit, type reboot and try again.
If you try to run node /home/pi/osc/osc_control.js
and encounter an error like:
pi@xx: ~ $ node /home/pi/osc/osc_control.js
module.js:549
throw err;
^

It's because the node_modules are not in the /home/pi/ directory. Check for that folder, if it is there and still not working, then they may not be installed. Type in npm ls to see which modules are availible.
A fix for this: type cd and hit enter. To make sure your at the Pi home dir.
Then type: cd node-v8.11.3-linux-armv7l/
type ls again to make sure that the node_modules is in this dir. You may have moved it, if not.
If it is type: sudo cp -R * /home/pi/ to these folders to the home dir. Type cd to go back and then type npm ls again to see if the modules are listed.
Don't know your ip address try: ssh [email protected]
Newer version of node.js
wget https://nodejs.org/dist/v8.12.0/node-v8.12.0-linux-armv7l.tar.xz
tar -xf node-v8.12.0-linux-armv7l.tar.xz
