Hi. I tested your recommendation (to use GPIO B+/Pi2) but still all the GPIO pins are initially in TRUE value after running the program. See attached picture. Thanks :))
ok.. this will help me a lot. thank you very much sir!!. will delete the other thread.
i was wondering if my new raspberry pi 4 is supported by codesys rpi control. i've seen many videos on youtube with codesys using raspberry pi as PLC.
what do you mean by project archive sir? i recently uploaded my files on the same thread under engineering forum, here's the link : https://forge.codesys.com/forge/talk/Engineering/thread/a45c28372c/
Is this the files you needed sir? thanks in advance for your help sir
