display activation needed different initialisation for my OLED #2

Instead of the lines:

// create display device
#define OLED_RESET -1  // unused port - to keep the compiler happy
Adafruit_SSD1306 display(OLED_RESET);

I needed to put in the following (found in the Adafruit example). After that, "guru meditations" stopped, and the unit came to life :)

// Declaration for an SSD1306 display connected to I2C (SDA, SCL pins)
#define OLED_RESET     -1 // Reset pin # (or -1 if sharing Arduino reset pin)
Adafruit_SSD1306 display(128, 32, &Wire, OLED_RESET);

Mine too - This really needs to be updated, I went through several OLED boards before thinking to check the open bugs and finding this tidbit.
