I have an NHD-7.0-800480EF-20 Controller board, but the data sheet has a few holes. I want to use the 20-pin MPU Interface connector, but need to know the following before I inadvertently blow something up:
1) What voltage wants to be present on Pin 3 (the B/L Enable pin)?
2) Is the B/L Enable pin truly an enable, or (as the data sheet seems top imply) is it a power supply input pin?
3) I'm assuming that the Display On signal (Pin 19) is active high. Does it default to a particular state, or does it need to be actively driven to turn the display on?
Any help is appreciated.
