sunray for RPi@landrumower: Lost in confusion

[Sunflare]

Hi All,
somehow, I have trouble to get the software configuration and installation straight in my head.
I hope someone here is able and willing to help me:
I have

• the Landrumower PCB
• A Raspberry Pi 4B
• A raspberyPi Pico

I would like to run a Mower based on sunray (for Alfred, not OWL) with Cassadra doing the "coordination".
Cassandra and sunray should run both on the RPi 4B

I believe I understood the following:

• The Pico
  • does the hardware control (switches, motors, odometry counting, battery measurements, ...)
  • talks to the RPi via UART
  • receives commands from RPi
  • sends sensordata to RPi
  • I took a micropython firmware from here Sunray/landrumower/firmware/2.x at landrumower-linux · EinEinfach/Sunray
    
• The RPi with Cassandra:
  • Gives me a GUI in a Browser
  • talks to sunray (on the same host in my case)
    • with HTTP request, MQTT or UART
  • Provides the high-level control (Maps, schedule, etc.)
  • I was able to install and run Cassandra following the instructions here GitHub - EinEinfach/CaSSAndRA: Cascaded sunray server and rover application
    
• The RPi with sunray (that's my personal challenge)
  • It's supposed to make the low-level control (GPS/RTK, track following, battery monitoring, motor control, ...)
  • I found the information to choose the Repo/branch GitHub - EinEinfach/Sunray at landrumower-linux
  • I cloned it and tried to understand the structure but although I find a subtree Sunray/sunray (with config.h),
    the instructions only tell me to operate in Sunray/alfred (for Alfred) with its config.h.
    But I intend to build sunray (firmware) not Alfred.

My two questions are:

1. Did I get the structure and functions right as far as I got (if not, please explain)?
   
   
2. What is the proper procedure and repo+path to compile and install a working "sunray firmware" that i can connect to Cassandra on one end and to the Pico-Firmware on the other end for my RPi based hardware configuration? (I didn't see a thread where that part is explained!)

Thanks in advance!

Thomas

Hi,
I think youre missing the sunray_install folder.
I have used this oneSunray Installation auf Raspberry

Then adjust your config.h and compile sunray with service.sh in Sunray/alfred
I made some notes for myself, when i installed this on a orangepi zero2w.
