|
|
* This module provides read/write from and to a framebuffer in RAM. This is
|
|
* needed when using a controller that does not provide a way to read back data
|
|
* from the LCD controller memory. In this case we need to buffer the data in
|
|
* a local framebuffer to allow manipulation on pixel level. It is generally
|
|
* not recommended to access the framebuffer directly; this is handled by the
|
|
* graphic driver when needed.
