about

these scripts connect a gamepad to rnbo via bluetooth, and rnbo to the teensy via usb serial, for use with sousaFX-rnbo

setup overview

https://rnbo.cycling74.com/learn/raspberry-pi-setup

ssh

ssh pi@c74rpi.local or ssh pi@192.168.1.xx

update

"Processing triggers for man-db" takes ages. Try this before apt-get next time: echo "set man-db/auto-update false" | debconf-communicate; dpkg-reconfigure man-db from https://askubuntu.com/a/1437819

sudo apt-get update && sudo apt-get upgrade
sudo apt update && sudo apt upgrade

mount

install macfuse and sshfs https://macfuse.github.io/

sshfs pi@192.168.1.xx:/home/pi ~/Desktop/raspberry_pi -o defer_permissions,noappledouble,nolocalcaches,volname=RaspberryPi

clone: cd /Users/<user>/Desktop/raspberry_pi/home/pi/; git clone https://github.com/Sousastep/sousaFX-rpi-scripts.git

install

sudo apt install python3-evdev python3-liblo python3-serial build-essential liblo-dev libevdev-dev

enable audio interface

~/.asoundrc

defaults.pcm.card 3
defaults.pcm.device 0
defaults.ctl.card 3

or

cd sousaFX-rpi-scripts/
cp .asoundrc ~/.asoundrc

enable bluetooth and pair controller

put controller in pairing mode, then

sudo bluetoothctl
power on
agent on
default-agent
scan on
scan off
pair [XX:XX:XX:XX:XX:XX]
connect [XX:XX:XX:XX:XX:XX]
trust [XX:XX:XX:XX:XX:XX]
exit

[CHG] Device XX:XX:XX:XX:XX:XX Connected: yes
[CHG] Device XX:XX:XX:XX:XX:XX Connected: no
[CHG] Device XX:XX:XX:XX:XX:XX Connected: yes

try remove XX:XX:XX:XX:XX:XX

build

cd ~/sousaFX-rpi-scripts;
g++ -O3 oscserial.cpp -o oscserial -llo -lpthread;
g++ -O3 gamepad.cpp -o gamepad -llo;

auto-run scripts on startup

cd sousaFX-rpi-scripts/
sudo cp gamepad.service /etc/systemd/system/
sudo cp oscserial.service /etc/systemd/system/
sudo systemctl enable gamepad.service && sudo systemctl enable oscserial.service

run

sudo systemctl start gamepad.service
sudo systemctl start oscserial.service

status

sudo systemctl status gamepad.service && sudo systemctl status oscserial.service

logs

sudo journalctl -u gamepad.service
sudo journalctl -u oscserial.service

connecting android to rpi

turn on android hotspot

connect rpi to hotspot via sudo nmtui: https://rnbo.cycling74.com/learn/raspberry-pi-setup#current-image-1.3.0-and-greater

find IP with termux: https://cycling74.com/forums/how-to-connect-raspberry-pi-to-android-hotspot

reinstalling

when sshing after reinstalling, you'll see
