Hi, I've recently upgraded from a PI2 to a Pi4 and I cannot get my program working. At first I just swapped the SD card from the PI2 to PI4 and the program ran for a few seconds and then crashed.
I later reinstalled PI os and upgraded the runtime/device(in codesys) to version 4. but my program won't compile and gives me the following error:
[ERROR] raspberry pi peripherals, 184.108.40.206 (3s - smart software solutions gmbh): C0521: The library "raspberry pi peripherals, 220.127.116.11 (3s - smart software solutions gmbh)" was created with the unknown compiler version "18.104.22.168".
I have encountered this problem if the runtime is updated but the project setting is still set to a specific compiler version. Check under "Project Settings > Compile options" and make sure the project settings matches your compiler version (IDE version).
