TextLCD / TextLCD Enhanced library for ER-OLEDM2002-1_Series in I2C mode with Arduino

Hi,

I purchased a couple of 2002 character OLED displays (ER-OLEDM2002-1_Series) from East Rising Technology (BuyDisplay.com) with the intention of using the inbuilt I²C option to interface with my Arduino Mega 2560 R3. The displays use the US2066 controller.

I soldered jumpers appropriately on the BS0/BS1/BS2 bus interface pins behind the OLED displays to the required 010 to set up I²C mode. I also made the following connections between the OLED pins and Arduino:

GND: to GND (Vss)

Vdd: to 3.3 V

D7, D6, D5, D4 and D3: all to GND (Vss)

D2 and D1: tied together and to SDA pin

D0: to SCL pin

RD: to GND (Vss)

RW: to GND (Vss)

DC: to GND (Vss) or 3.3 V (Vdd) to set address as either 0x3C or 0x3D

RES: to 3.3 V (Vdd) as datasheet advises pulling it HIGH during normal operation

CS: to GND (Vss)

I am wondering whether I can use the TextLCD or TextLCD Enhanced library to get these displays to work in I²C mode, with my Arduino Mega. If so, would you be able to help me get started, by telling me what modifications need to be made to the library code, and/or provide me with a sample Arduino sketch.

I have attached all the relevant datasheets.

Thanks for your help!

Chakko.
