hitachi lcd pinout
Hey guys!
I've got a LCD display with a HD44780A00 driver. It's actually the first time i'm using a display. I got it from a friend who has another friend who's working/debugging public payphones. He got a bunch from the company, since he's an engineer, and i got one
but he got no datasheet or anything. It simply has two columns of pins, each with 7 pins. The columns are on the height of the LCD display. I've looked over the driver's datasheet. The GND pin is connected to the lower pin of the second column. I'm really not able to find out the other pinning. I've made a very simple drawing, with the GND pin as red.
The correspondent pin on the first row is tied to Vcc (checked with datasheet). There's also a small 1 wrote on its trace.
Can anyone explain me the rest of the pins? I've googled a bit, but nothing useful came out. The module doesn't even have a name.
Many thanks,
izua
I've also attached a picture. This is the side with the chips, pins are facing me:
edit, i can't attach the picture. whatever i do, the url gets screwed somehow. If you have the time, here is the link: **broken link removed**
I'm not going to write on it right now, since i'll still have to do some research, but i want to light it at least.. what pins should I connect? Thanks again![/img]
