build raspbian image to run godot binaries

1. Install latest raspbian lite distro (get image, run imager)

2. sudo raspi-confi: enable wireless, enable ssh, change login/pwd,  GL FKMS driver

3. (optional)  "lcd_rotate=2" in /boot/config.txt to flip the screen upside down 

4. sudo apt-get update, full-upgrade, clean

5. sudo apt install  libegl1-mesa  libgles2-mesa

FIRST TIME RUN FROM TERMINAL, NOT SSH otherwise it'll use llvmpipe (sw pipeline) instead of  V3D 4.2

build raspbian image to build godot + frt

1. do the previous steps for godot binaries

2. sudo apt install  git

3. git clone https://github.com/godotengine/godot.git

   1. git checkout remotes/origin/3.2-gles2-batching

   2. cd godot/platform, git clone  https://github.com/efornara/frt.git

4. sudo apt  install  scons  libgles2-mesa-dev libudev-dev libasound2-dev libpulse-dev  libgbm-dev libdrm-dev

5. scons platform=frt target=release frt_arch=pi4 tools=no module_webm_enabled=no bits=64 -j4

DiY moonboard stuff:

1. https://github.com/e-sr/moonboard

2. install python3, python3-dev

3. install pip, easy_install3.7 requests

   1. sudo /usr/bin/python3 -m pip  install websockets

   2. sudo /usr/bin/python3 -m pip  install aiosqlite

   3. sudo /usr/bin/python3 -m pip  install python-periphery

   4. sudo /usr/bin/python3 -m pip  install bibliopixel

4. enable spi in raspi-config

   1. copy com.moonboard.conf to /etc/dbus-1/system.d

   2. copy com.moonboard.service to /usr/share/dbus-1/system-services

5. requirements.txt

MODEP (raspberry pi effects board)

To install:

1. Make an image (Raspberry Pi OS 64-bit bookworm with desktop in my case) on the SD-card.

2. Install the SD-card and let the basic setup complete.

3. Install the Pisound and modep software (first time you run the Pisound installation it asks for a system update, you must perform that extra action):

sudo curl https://blokas.io/apt-setup.sh | sh

sudo apt install modep

To launch:

1. With your Scarlet (audio interface) plugged into the Pi, run the aplay -l and arecord -l commands 

2. edit the following file:/etc/jackdrc

3. replace hw:pisound with hw:3,0 (or whatever number your interface shows above). Once that has been updated restart jack with the following command:

4. sudo systemctl restart jack then restart MODEP with the following command:

5. sudo systemctl restart modep-mod-ui

Example line for better sampling: 

• exec /usr/bin/jackd -t 2000 -R -P 95 -d alsa -d hw:pisound -r 48000 -p 64 -n 3 -X seq -s
