I got i2c SSD1306 working no issues when I got usable libraries [_GFX , SSD1306] it ran their sample Adafruit demo sketch using Wire.h.
I just got my Prop Shield out and removed EEPROM calls and the CalibrateSensors is running with copious data- Assume that is a second test of i2c?

@mjs513 - found it … right there on page #96 post #2388 … so that would have been w/T4B2 hardware … had to take out the EEPROM setting for the calibration.
