We use a Raspberry Pi 4 as a "main controller" to:

1. attach a touchscreen to display and interact with the Plant Imager user interface
2. control the CNC (with Oquam) over USB
3. create an access point
4. control the PiCamera(s)

It thus acts as an Access Point (a.k.a. Hotspot) for the other devices, notably for the PiCamera(s) (Pi Zero W).

Note

The Ethernet connection is not mandatory, you may want to isolate this from the internet for security reasons!

As the above schematic illustrate, in the following steps you will create a local network.

This will require to choose:

• an SSID, that is the name of the network the other devices will connect to

For the sake of clarity, we will use:

• SSID: Plant Imager
• password: my_secret_password!

Warning

Change the password as it is not so secret anymore, and use a strong one!

As the above schematic illustrate, in the following steps you will set up several Operating Systems.

This will require to choose:

For the sake of clarity, we will use:

• username: romi
• password: my_raspberry!

Warning

Change the password as it is not so secret anymore, and use a strong one!
