Hi, I too like the 16x2 Character OLED displays. I also need to connect it to my Arduino Uno R3 via I2C.
I followed this thread any several others and found that these OLED displays are made by NEWHAVEN
Apparently there are timing issues when using the standard Arduino LiquidCrystallibrary 4 bit/8bit parallel.
A company in japan has made a I2C backpack board for about $14.00 that they say works with the NewHaven NHD-0216KZW-AB5 oled blue 16x2 display. I think this is the same 16x2 blue oled that this thread is talking about. They also have written their own replacement lib for the Arduino LiquidCrystal library called TWILCD
So.... my question is does anybody know if the adafruit i2c / SPI character LCD backpack - ID: 292 will work when attached to this oled display and which I2C library to use? (WIRE, I2CMASTER, this TWILCD library, other)
Apparently these oled displays come in 16x2, 20x4, and graphic screens. They come in blue, green, and yellow.
