What is this?

A sample code for AQM0802A-RN-GBW. You can see animated SWITCH SCIENCE text logo.
This LCD is 3.3V, I2C, 8 digit 2 line, tiny (30mm x 19.5mm) text LCD.
I found this at Akizuki Denshi Tsusho. http://akizukidenshi.com/catalog/g/gP-06669/

This LCD has 9 pin connector. Pin-out is,

1 VO
2 VOUT
3 CAP1N
4 CAP1P
5 VDD
6 VSS
7 SDA
8 SCL
9 XRSETB

Here is how to connect LCD and mbed.

Since this LCD has a 1.5mm pitch terminal, I needed to do naughty soldering to play with bread-board.
I soldered 2x 10kohm to pull-up I2C bus.

Additional information

You can control this LCD with Tedd OKANO's TextLCD_SB1602E library.
When I use this code with my mbed NXP LPC11U24, I needed to update mbed libary.

Import programTextLCD_SB1602E
