    Hi Stefan,

    Yes ... It was great fun! We did numerous I2C devices we found in our stock. In fact, for their midterm they all received unique I2C chip ranging from thermometers, potentiometers, DAC, ADC to RTC and had to write the device driver.

    However we stick to building the driver FB and not compile it in to a library from now on. Why you might ask ... It is kind of a pain in the bud to keep track of the system unique device ID codes. [edit]If by mistake a duplicate is made you end up with continuously installing and removing devices from the repository. Kind of annoying that is.

    When I get round to it I'll write a short how to for future reference, i will post it in this forum.

    Koen.

    Hi Koen,

    I know this problem to well. On CODESYS Forge, we created a Device Registry for this:

    https://forge.codesys.com/drv/io-drivers/database/

    Just in case you want to publish your drivers...

    BR,

    I just released a new IoDriver on cForge.
    I also will soon revisit the Monarco HAT for an upgrade.

    Many thanks to @Ingo Hornberger for his patience and willingness to help!
