Hello! I just found that Active Surplus was selling these little 16x2 LCDs for $1!
It's a very simple circuit board, LCD on the front, as well as two button contacts labelled "clear" and "secure". On the back, there is a single HD44100H driver, and a 10 pin ribbon connector leading from the driver. I bought one, because a quick google search on my phone at the time lead me to believe that the HD44100H was similar in operation to the HD44780, which is widely supported by almost every LCD-controlling software on Windows.
Now how would I get this working on my PC? I assume I would need to build some sort of USB to RS232 converter, I have a very simple circuit I have built before for that, so that's no trouble. But does anyone have any idea which pins do what?
