SSD1306_OLED_HW_I2C_LIB2

This is an enhanced version of SSD1306_OLED_HW_I2C_LIB with additional 32 line display support for the SSD1306 128 x 32 OLED display.

Note:

• SSD1306_OLED_HW_I2C_LIB is not required
• SSD1306_OLED_HW_I2C_LIB2 is a base class

Displays Supported:

• 128 x 32
• 128 x 64

This library was created using the SSD1306_OLED_HW_I2C code written by Ilya Perederiy (see New minimalistic library for 128x64 I2C OLED displays). SSD1306_OLED_HW_I2C was, in turn, derived from the Tinusaur SSD1306xLED code, which can be found here: Tinusaur / The Tinusaur Project / SSD1306xLED.

There are a number of derived classes, from this base class, which add compatability with the print() function (derived from Arduino Print class), larger 8x16 characters, and additional dashed vertical line drawing (D_DRAW_VERT_DASHED()). These classes are:

• SSD1306_OLED_HW_I2C_PRINT_LIB
• SSD1306_OLED_HW_I2C_PRINT_8X16_LIB
• SSD1306_OLED_HW_I2C_PRINT_8X16_DASH_LIB

In addition, there are "wrapper" classes, to some of the above derived classes, which provide standard Arduino begin(), clear() as well as other functions, such as:

• Character based cursor placement, setCursor() and setCursorMode();
• Larger character selection, setPrint8x16CharacterMode(), and;
• Dashed vertical line drawing, D_DRAW_VERT_DASHED().

These should be used in Arduino projects as they aim to provide plug in capabilities, as a display driver for the SSD1306, for existing Arduino projects:

• Small_SSD1306_Print_8x16_lib
• Small_SSD1306_Print_8x16_Dash_lib
