GraphLCD driver library
The Framebuffer driver
---------------------------------------------------------------------
Description
-----------
The Framebuffer driver writes the output to the framebuffer device at
/dev/fb0.
The driver is optimized for a 640x480x16 framebuffer. To use it, have
a kernel with a framebuffer device (e.g. vesa fb) and add e.g.
vga=0311 to the kernel init parameters (e.g. in lilo.conf).
Configuration Parameters
------------------------
The Framebuffer driver supports the following parameters in config
file:
Width
Sets the horizontal size of the display. If this parameter is not
given, a default value of 320 pixels is used.
Height
Sets the vertical size of the display. If this parameter is not
given, a default value of 240 pixels is used.
UpsideDown
Rotates the display output by 180 degrees. This might be useful, if
the LCD is mounted upside-down.
Possible values: 'yes', 'no'
Default value: 'no'
Invert
Inverts the display.
Possible values: 'yes', 'no'
Default value: 'no'
Zoom
Determines if pixels should be drawn double sized.
Possible values: 0, 1
