Plant Imager communicationsLink

OverviewLink

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).

Overview of the connectivity for the Plant Imager v3.

Note

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

Access pointLink

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
  • a password, to restrict access to this network

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!

RaspberryPi OSLink

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

This will require to choose:

  • a username, that is the name of the (admin) user
  • a password, to restrict access to this device

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!
