A rather strange request this one. I am using a LK202-25 for my <a href=http://www.chiark.com/scooby/limp.asp>in-car MP3 player</A> but, as you'd expect, I've found that I really should have ordered a VFD.
Soooo, after a bit of research, I've found that Noritake make a direct LCD replacement VFD that has the same pin-outs and commands (HD44780) as the LCD part used by the LK202 (Ampire)
Question is, can I remove the LCD and simply strap on the Noritake VFD, thus making my LK202-25 into a VK202-25? The only difference is that the LCD uses a varirable voltage on pin 3 to control contrast whereas VFD requires a command sending to change brightness. (Am I best off leaving Pin 3 disconnected?)
The VK manual lists a Brightness command, and the LK manual doesn't, but I'm guessing that they both use the same processor boards given that the board says both LK and VK on it... Some other commands are different, but nothing radical apart from Startup screen. There's no "overlaps" in the command set.
Anyone have any ideas? Thanks in advance
