2  Using Arduino / Displays / Arduino library for Mitsubishi 50530 LCD displays ( 40x3 ) on: March 28, 2012, 03:45:46 am
Hello,

Here's a first version of a library for LCD displays based on the Mitsubishi 50530 chip.

https://github.com/sponnet/LCD50530/

We have tested it on an Optrex DMC-50652N display , but it should also work on a Seiko/IIS C456002A

We'll add cleaner wiring diagram later, but the data pins should be at :

digital 0 -> DB7 (databit 7)
digital 1 ->  DB6 (databit 6)
digital 2 ->  DB5 (databit 5)
digital 3 ->  DB4 (databit 4)
digital 4 ->  EX (Execute)   
digital 5 ->  R/W (Read/Write)
digital 6 ->  I/OC1 (IO Control 1)
digital 7 ->  I/OC2 (IO Control 2)

5V -> VSS (GND)
Gnd -> Vdd (logic power)

VLCD (LCD power) should get a voltage of 12v in our tests , or the LCD display shows no characters ( in our test ), so you need an external power source for that...

Remarks are welcome !
