Changes in configuration files generated in pncconfig for 7i76 to 7i78

Hello. I would like to advise how to change the configuration files (I assume it concerns .hal and .ini) generated by the pncconfig program for 7i76. Linuxcnc is installed on 7c81 and the firmware is for two 7i78. Two axes for the lathe and most of the necessary switches are without problems. However, I need control of the main spindle and input from the incremental encoder for the spindle and a serial port for the 7i73 handwheel and possibly additional buttons.
I apologize for the possibly trivial question. But I had a break from using Linuxcnc for several years and I simply forgot a lot of things, not to mention that many things were never completely clear to me.Now that I'm retired, I finally have enough time for all of this, but unfortunately, it's too complex for me.
