Hallo Uwe,
ich würde es mit revpimodio2 und IO events realisieren (https://revpimodio.org/doku2/io/). Der Funktion reg_event kannst du über den Parameter edge=RISING mitteilen, dass die Event-Funktion nur bei steigender ausgeführt wird. Dort kannst du dann deinen Zähler hochzählen.

Re: Byte-order Problem
Hallo fbarthez, ich habe mir deinen Anwendungsfall mal etwas genauer angeschaut und es hier nachgebaut. Wie du schon richtig erkannt hast unterscheidet sich die Reihenfolge der jeweiligen Bytes in Device und im Prozessabbild. Der RevPi basiert auf eine little endian Architektur und speichert daher a...

Hi Anton,

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.

Re: Upgrade from 1.2.9 to 2.0.0
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/...

Re: Touchscreen press backwards?
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)?
