I am having a lot of bad luck lately. Local electronics stores REALLY suck here...
Yesterday I bought an LCD display "Parallax 4x20 Serial LCD, 27979", when I got home and open the package it was a display but a completely different model, with only one line.
I went today to return it, but they did not have replacement, the only other LCD they had was a HC16201 (only 2 lines, but it's cheap, so I bought 2 of them)
I am trying for HOURS to find the data-sheet for it, but the only thing I find is this one page PDF:
http://www.britestone.com/shop/upload/DN/LCD/HC-16201.pdf
I looked for a similar LCD, and found this: HC16202NY-LY
The data-sheet gives more info, but I still don't see what data to send to it in order to display the text I need... I don't see a list of commands, or a ASCII chart, like I usually see in LCD data-sheets.
Can someone help me find out how to use it ?
PS. I will use a PIC microcomputer to interface with it.
