MB2HAL error

I have testet without sudo and it still works . So i can exclude this error. Anyone another idea?

Hello
Today I managed to get the vfd to connect without an error after calling Mb2hal.ini in a terminal. Now I can go to Custom.hal. Thanks to the help from everyone first. I will contact you as soon as I have progressed or have a question about it.
regards
Michael

Hello
I now had support from my son (computer science student) and we were now able to set up the VFD and control it with gmoccapy. the whole thing looks like this now.




The VFD works without problems and Gmoccapy also shows the changes via speed and LED.
I am grateful for any information about making adjustments.
