Are the drivers really documented so badly? I hoped that they are helpful. Your approach was fully correct this far. If you started with the MCP3008, you should already be fine. Just make sure, that you use a unique ID, as described here: https://forge.codesys.com/drv/io-drivers/doc/Generic/#device-identification If you are curious about a specific concept, we can discuss this separatly.

But now I wanted to read all the documentation here to fully correct the code and put it on the CODESYS Forge, and I struggle. For an SPI I/O driver: do I have to follow the SPI guidelines and/or follow the generic guidelines and/or follow the Driver FB guidelines??? It's very confusing to me. At the beginning there are three sentences,...

Hi all, I am new to CODESYS and decided to start with the tutorial Your first CODESYS program I get so far as to establish a connection to PLC. I get 'Device User Logon' prompt requiring me enter username and password when I am trying to set the active path. The device is set to 'CODESYS Control Win V3 x64'. I had it to 'CODESYS Control Win V3' before (as described in the tutorial), but in the Scan network the controller was greyed out so I updated device to x64. Then the controller could be selected...
