SSD1306 Displays

-----------------------------------------------------------------------

The driver is used in multiple displays (128x64, 128x32, etc.).

Select the appropriate display below to create an appropriately

sized framebuffer, etc.

SSD1306_128_64  128x64 pixel display

SSD1306_128_32  128x32 pixel display

You also need to set the LCDWIDTH and LCDHEIGHT defines to an

appropriate size
