What does the "Command" in Set and Save Data Lock do?
Posted: Thu Nov 23, 2023 10:00 am
I'm working with a LK204-7T LCD and it randomly displays garbage characters/ messes up it's contrast etc. after rebooting the unit it's fixed on. My suspicion is the mother board is sending some random data towards it via the serial com port and it somehow manages to turn off the set save data lock in the panel.
Previously the Set and Save Data Lock was only locking the display, but since the garbage values persists, I'm experimenting with locking all display, command, settings and address levels. I've noticed that adding `Command` has created more issues in the panel and the documentation is very vague on what each level does.
So does anyone know what locking `Command` will actually do?
