Dual Shock / PS3 Bluetooth Remote Pendant for CNCjs

Use Playstation 3 Controller wirelessly over bluetooth to control CNC from the host device (raspberry pi). PS3 CNC Control Button Map

Remote Pendant (Playstation 3 Dualshock Controller / SIXAXIS Controller)

Using a wireless game controller (like a PS3 controller) seems to be one of the lowest cost & simplest solution method. See related issue #103

Playstation Controller Setup ( general guide to connect hardware & setup )

Here is what I have figured out so far for PS3 on Raspberry PI 3 w/ integrated bluetooth.
The bellow just shows how to get PS3 controller connected.

Bluetooth Configuration

$3


Install & Enable Bluetooth Tools

sudo apt-get install -y bluetooth libbluetooth3 libusb-dev
sudo systemctl enable bluetooth.service
Add pi user to bluetooth group

sudo usermod -G bluetooth -a pi

$3


Get and build the command line pairing tool (sixpair)

wget http://www.pabr.org/sixlinux/sixpair.c
gcc -o sixpair sixpair.c -lusb
$3

Get PS3 DS 

sudo ./sixpair

$3


$3
Start bluetoothctl:

bluetoothctl
Enable the agent and set it as default:

agent on
default-agent
Power on the Bluetooth controller, and set it as discoverable and pairable:

power on
discoverable on
pairable on
$3
Discover the DualShock 3 MAC address:

devices
$3
#Allow the service authorization request:
#[agent]Authorize service service_uuid (yes/no): yes
#Trust the DualShock 3:
#trust device_mac_address # Replace "MAC" with MAC of "Device 64:D4:BD:B3:9E:66 PLAYSTATION(R)3 Controller"
trust 64:D4:BD:B3:9E:66 
The DualShock 3 is now paired:

quit
Turn the DualShock 3 off when it's no longer in use by pressing and holding the PlayStation button for 10 seconds.

Press the PlayStation button to use the DualShock 3 again.

List Devices

ls /dev/input

cat "/sys/class/power_supply/sony_controller_battery_64:d4:bd:b3:9e:66/capacity"

$3


Install

sudo apt-get -y install joystick
Usage / Test

jstest /dev/input/js0

Install NodeJS Libraries

 - https://www.npmjs.com/package/dualshock-controller

Install Tools

sudo apt-get install -y libudev-dev libusb-1.0-0 libusb-1.0-0-dev build-essential git
sudo apt-get install -y gcc-4.8 g++-4.8 && export CXX=g++-4.8
#npm install node-gyp node-pre-gyp
Install node-hid with hidraw support

#npm install node-hid --driver=hidraw --build-from-source --unsafe-perm
Install Pendant Package

sudo npm install -g cncjs-pendant-ps3 --unsafe-perm  # Install Globally
If NOT installed globally, Install node-hid with hidraw support (https://github.com/rdepena/node-dualshock-controller)

$3


Run as Root

sudo su
You will need to create a udev rule to be able to access the hid stream as a non root user.

sudo touch /etc/udev/rules.d/61-dualshock.rules
sudo cat <> /etc/udev/rules.d/61-dualshock.rules
SUBSYSTEM=="input", GROUP="input", MODE="0666"
SUBSYSTEM=="usb", ATTRS{idVendor}=="054c", ATTRS{idProduct}=="0268", MODE:="666", GROUP="plugdev"
KERNEL=="hidraw*", SUBSYSTEM=="hidraw", MODE="0664", GROUP="plugdev"
SUBSYSTEM=="input", GROUP="input", MODE="0666"
SUBSYSTEM=="usb", ATTRS{idVendor}=="054c", ATTRS{idProduct}=="05c4", MODE:="666", GROUP="plugdev"
KERNEL=="hidraw*", SUBSYSTEM=="hidraw", MODE="0664", GROUP="plugdev"
EOT
Reload the rules, then disconnect/connect the controller.

sudo udevadm control --reload-rules

exit`

`QUICK FIX for node-hid hidraw... PLEASE HELP IF YOU KNOW FIX`


I am having issues with node-hid --driver=hidraw not seeming to work... quickest fix is to reinstall, node-hid --driver=hidraw 
Reinstall (node-hid --driver=hidraw) on cncjs-pendant-ps3

cd /usr/lib/node_modules/cncjs-pendant-ps3/
sudo npm install node-hid --driver=hidraw --build-from-source --unsafe-perm

I recommend rebooting now. After reboot you can test pendant by runningcncjs-pendant-ps3 -p "/dev/ttyUSB0".

----------------------------------------

`Auto Start`

`$3`


Install Production Process Manager [PM2]

npm install pm2 -g
Setup PM2 Startup Script

pm2 startup debian
  #[PM2] You have to run this command as root. Execute the following command:
  sudo su -c "env PATH=$PATH:/home/pi/.nvm/versions/node/v4.5.0/bin pm2 startup debian -u pi --hp /home/pi"
Start Dual Shock / PS3 Bluetooth Remote Pendant for CNCjs (conected to serail device @ /dev/ttyUSB0) with PM2

pm2 start $(which cncjs-pendant-ps3) -- -p "/dev/ttyUSB0"
Set current running apps to startup

pm2 save
Get list of PM2 processes

pm2 list
