I would like to drive a SSD1306 OLED display from my databot2.0 using the i2c protocol. My OLED display works great with an Uno board, at both 3.3 or 5.0 volts. But when I connect it to the i2c port on the databot, it does not work. When I run an i2c scanner program the ssd1306 is not seen (although the internal databot i2c sensors are seen). I am hooking up the i2c signals lines from the databot2.0 i2c port to the ssd1306 display as described in the databot2.0 deep geek section. Does anyone have experience in getting the databot2.0 to drive an i2c display?
Thanks!
