    Hi,
    this you need to add in the device descripton:
    "c:\Users\<yourwindowsname>\CODESYS Control for Raspberry PI\3.5.11.10\Devices\MCP23S17.devdesc.xml"
    "c:\Users\<yourwindowsname>\CODESYS Control for Raspberry PI\3.5.11.0\Libraries\SPI_MCP23S17.library"
    Then you need to extend the library to read the paramter.</yourwindowsname></yourwindowsname>

    After changing adding lines in the devicedescription the steps should be:
    Install the devicedescription to the device repoditory and then execute update device by rightclick in the device tree -> update device (then the edited and Change devdesc is used)

    Hi Fabio, many are doing their own drivers in forge take a look at the documentation how to.
    https://forge.codesys.com/drv/io-drivers/doc/I2C/
    Can seem a little daunting but really it is achievable.
    Please let me know if you get stuck or want advice on a particular point. You can also ask in forge itself
