+= SSD1306 Driver for ATTiny controllers =
+
+SSD1306 is library intended to work with SSD1306 I2C OLED
+Displays. First of all, it is developed for ATTiny controllers
+to use as few resources as possible, because of limitation
+to SRAM (512 bytes) and Flash (8K). Since ATTiny controller
+has no division and multiply operations, the library has
+some limited functionaly. But it is still can be used to
+develop simple graphics applications.
+
+Key Features:
+
+ * Low level I2C OLED Driver functions (ssd1306_i2c.h)
+ * High level I2C OLED Driver functions (ssd1306.h)
+ * Some memory-buffered operations (nano_gfx.h)
+ * Third-party font (6x8)
+ * Some functions are:
+ ** Filling display with pattern data
+ ** Printing text to display
+ ** Drawing bitmap image from SRAM memory
+ ** Drawing bitmap image from Flash memory (PROGMEM related)
+ ** Sprites: moving
+ ** Drawing lines in buffer
+
+For Attiny controllers OLED display must be connected to
+PB3 (SCL) and PB4 (SDA) lines. For other controllers connections
+are programmed to A5 (SCL) and A4 (SDA) lines. The pins
+can be modified in ssd1306_pins.h file.
+
+For more information about this library please visit
+https://github.com/lexus2k/ssd1306.
+If you found any problem, please report to Issues section.
