Does anyone know of any programmable LCD controller?
Something like this: http://store.earthlcd.com/s.nl/sc.7/category.297/it.A/id.3226/.f
It should be programmable through USB/RS232, and it does not have to be colour.
At work, we are building a digital VCR-type appliance and need a display for the front panel. There is not an electronics expert, so we need something that is easily programmable through standard interfaces/ports.

This is exactly what I am looking for. If anyone knows of similar and cheaper models, please reply.

If anyone looks for this thread sometime, there are also many LCDs from:

Do you need a graphics or character only model? I have experience programming the character ones, but havent tried working with the character ones. (They are out of my price range :D)
Character will also do. Do you have any recommendation?
I always wondered... why these outrageous prices? That's what kept me from filling my apartment with lcd-enabled devices when I was a pupil
Hmm those on crystalfontz are cheaper - the types I needed back then when I was making electronics all the time. At that time the cheapest ones were $40 here...
Dont know about the prices but if you are near Germany

I've used LCD character displays in my PIC work a lot, usually 2 lines of 8 chartacters, pretty cheap at $8 USD or so.
Needs just 6 or 7 data lines to write to them (the extra line is to read from them), used the usuale Hitachi (or clone) controller. Parallex uses this in their LDC appmod, which I coppied for my work too; the appmod also inclused 4 pushbutton switches on the same data lines. A usefull reuseable block.

Sounds pretty cute... how do you program them? Solder the LCD connectors to a RS-232 plug, then open a COM port and send data?
Serial LCD to PC

All the character ones act the same basically, they are complaint with the HD44780 chip. I used a parallel one, I didnt try the serial ones or the Crystal Fontz one. Though the mappings of the display character RAM is a bit weird, I suggest you read up on it beforehand as it can save ya some frustration (lol, you dont wanna go thru what I went thru!)
If your looking for just the controller, most people use Epson dot matrix controllers. If you want it combined then I would go with OPTREX. Look at the DMC series.
