    B4R Question rAdafruitSSD1306 lib (does NOT work) vs. Inline C (works)

    I have an ESP32 with an onboard OLED Display. @Peter Simpson wrote a nice example which works like a charm. Peter showed some connection parms but it doesn't work with the lib. The I2cScanner shows no devices. Could someone explain the problem? Is it a bug in the lib?
