I have this tiny OLED display (see photo). I want to use it with my Ameba RTL8195. I have tried the display on an Arduino Uno and it works fine. But I can't get it to work on the Ameba. I have connected it like this:
(oled -> ameba)
GND -> GND
VDD -> 3.3V
SCK -> I2C_SCL
SDA -> I2C_SDA
I've tried the Adafruit_SSD1306 and U8g2 libraries in all sorts of configurations (tried different pins etc). But nothing works, I haven't seen one pixel lit up using the Ameba.
Can somebody please point me in the right direction?
