Lego-Spike-Prime-OPCUA

This repo showcases an example how to utilize Lego Spike Prime engines and sensors together with OPC UA.

How to get the station running

• Setup a Raspberry Pi (I am using a Model 3B+)
• assemble the buildHAT as described in the manual
• connect a
  • Lego Force Sensor to buildHAT Port A
  • Lego Servo Motor to buildHAT Port C
  • Lego Light Matrix to buildHAT Port D
• connect via ssh to the RaspberryPI and follow some steps below

# Install dependencies
sudo apt install python3-build-hat

# Clone this repo and run the OPCUA server & station logic
git clone https://github.com/Spansky/lego-spike-prime-opcua.git 
cd lego-spike-prime-opcua

# Use the makefile to install and run the python project
make run

Project Structure

In /src you will find following files:

• station.py

  • establishes connection to the buildHAT and the connected devices/sensors
  • runs station internal logic, e.g. reacting on force sensor input, color led matrix

• opcuaserver.py

  • runs a OPCUA server using module asyncua

• main.py - Runs two async processes

  • opcuaserver
  • some station logic
