switched back to the last centrafuse.exe and my vfd display is back.
I went in, and made changes to the settings. clicked VFD OFF, VFD ON, restarted, etc. no output to the lcd.
so I switched back to the previous LCD and it started working again.
I dont really suffer from the cpu load so Ill stick to this exe till I get back from my vacation.
It's fixed! CPU usage during VFD scrolling is no different than CPU usage with the VFD module disabled.
Thank you for sticking with this David!
So... what'd ya' do?
I still do it for the init process, but just during the writing I switched it to simply sleep the microsecond delays and assume the write worked...
again though, it's working now so I'm happy...
