 /*
  *  Modified by Neal Horman 7/14/2012 for use in mbed
+ * 
+ *  Further modified by Istvan Cserny, January 31, 2022
+ *  so that it could be used for the SH1106 I2C display as well
+ *  The memory mode for the SSD1306 I2C display was changed to
+ *  Page mode (0x10) and the virtual void sendDisplayBuffer()
+ *  function has been rewritten accordingly.
+ *
+ *  To do: initialization of the SH1106 should be modified
+ *  althogh also work with the default initialization.
+ *
+ * 
+ * Example:
+ * @code
+ * #include "mbed.h"
+ * #include "Adafruit_SSD1306.h"
+ * 
+ * I2C i2c(D14,D15);
+ * Adafruit_SH1106_I2c oled(i2c, NC, 0x78, 64, 128);     // SH1106  I2C 128x64, with no reset pin
+ * // Adafruit_SSD1306_I2c oled(i2c, NC, 0x78, 64, 128); // SSD1306 I2C 128x64, with no reset pin
+ * // Adafruit_SSD1306_I2c oled(i2c, NC, 0x78, 32, 128); // SSD1306 I2C 128x32, with no reset pin
+ *  
+ *  
+ * int main()
+ * {
+ *     uint16_t x=0;
+ *     i2c.frequency(400000);
+ *     oled.setRotation(0);
+ *     oled.clearDisplay();
+ *     oled.drawRect(0,0,oled.width(),oled.height(),1); 
+ *     oled.display();
+ *     oled.setTextColor(1);
+ *     oled.setTextSize(1);
+ *     oled.setTextCursor(10,8);
+ *     oled.printf("SH1106 %ux%u",oled.width(),oled.height());
+ *     oled.display();
+ *     wait(2.0);
+ *     oled.setTextSize(2);
+ *     while(1) {
+ *         oled.clearDisplay();
+ *         oled.drawRect(0,0,oled.width(),oled.height(),1);
+ *         oled.setTextCursor(10,8);
+ *         oled.printf("x = %u",x++);
+ *         oled.display();
