I've recently purchased the POWERTIP PC1602F B LCD Screen (http://www.farnell.com/datasheets/4...23.1140453447.1528831294-380640216.1528405894).
Reading through, there are several things which aren't entirely clear:
1) Pin Description - VO (Operating Voltage for LCD). What does this actually do? No description is provided. The diagram below the table shows an arrow pointing out from the pin, towards a resistor. What does this mean... Is the resistor actually required, or only if you want to change the screen contrast?
2) What does the read pin do? Does it return the data you have sent to the screen?
3) Display Command Table. This is where most of the confusion arises. What do any of the various symbols mean (I/D, S/C, DL, NN, AC, X, etc)?
4) Assuming there are other LCD screen which work in a similar way, could somebody provide me with their datasheets, providing they make any more sense? Does any code exist for this particular screen?
Cheers.
