Hey Guys,
I'm using Codesys for the Raspberry Pi and searching for an option to configure my own device for the SPI/I2C bus? (it's a DA-Converter, MCP4725)
The SPI-master just offers a few prepared devices and no option for custom settings.
question: There are lots of posts explaining how to control Codesys via Python script but is it possible to start a Python script in codesys projects?
condition = true then starting python_script(a,b,..)
Thank you for helping!

I've got the same problem. Does really no one can help us? With the I2C-examples, you can only control the example devices, are there a bib for I2C devices in general?

a good startpoint is to read RaspberryPI_CodesysV3_FirstSteps_EN.pdf:
"c:\Users\<yourwindowsusername>\CODESYS Control for Raspberry PI\3.5.8.10\Documentation\RaspberryPI_CodesysV3_FirstSteps_EN.pdf"
In Chapter 4 'Connecting additional devices via I²C and SPI' there is a Basic description how it works.</yourwindowsusername>
See after reading this the 'open' libraries and devices here:
"c:\Users\<yourwindowsusername>\CODESYS Control for Raspberry PI\3.5.8.10\Libraries\" </yourwindowsusername>
open these libraries with CODESYS and check how they are implemented.
They use the I2C/SPI FB's from Raspberry Pi Periphials Library.
you need to implement a own device description for your device and install it then to the device repository

Hvae you had any luck getting some information, i am also trying to connect a device
where there is no specific device driver
