Re: Codesys with touch screen

Hi Uday_1009,

the RevPi Connect has no build-in wifi interface. You can use any linux compatible USB wifi adapter like the Edimax EW-7811Un.

Hi imerledragon Jessie was the major release two versions before our current Buster image. Therefore I'd highly suggest to upgrade the whole image instead of just updating the packages. You will find the detailed instructions in our tutorial: https://revolutionpi.com/tutorials/images/install-jessie/...

Hello Thomas,

great to hear that the problem could be solved with the help of DATA MODUL. Maybe you could share the solution here aswell, so others, facing the same issue, might find a solution here?

Re: WRITE ANALOG OUTPUTS THROUGH PROCESS IMAGE NOT WORKING

Hi LEOMENA,

you please try if the analog outputs are still unresponsive, when you stop the revpi nodered backend daemon (sudo systemctl stop noderedrevpinodes-server.service)?
