I'm currently working on an autonomous uploader so anyone can automate the production of usb devices.

Components

• a Raspberry Pi,
• a 16x2 LCD shield,
• (optional) a usb drive with devices repo from github.com/madnerdorg
• (optional) a smartphone/tablet to test the devices
• (optional) a 3D printer to make the case

Here is a prototype of this idea:

How does it works ?

Each github repo on github.com/madnerdorg/ have instructions for platformio.

On a terminal (with platformio installed) we can upload a sketch with this command:

platformio -f run -d /opt/arduino/test

platformio.ini

# Project Configuration File
# Arduino IDE compatible version

[platformio]
src_dir = buzzer
lib_dir = libraries

[env:nano]
platform = atmelavr
framework = arduino
board = nanoatmega328
targets = upload
# lib_install = 

I'm using a python script that will manage the lcd/buttons and run commands for platformio.

LibreConnect start at boot, and is stopped when a sketch is upload and then restart, once an arduino is programmed, it will be accessible as a websocket, ready to be tested.
