|
-----------------------------------------------------------------------
|
|
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
