/* LCD driver for the Samsung YP-S3
|
|
|
|
It appears that this player can contain two display types.
|
|
Detection of the display type is done by looking at the level of pin P0.4.
|
|
Currently only display "type 2" has been implemented and tested.
|
|
|
|
This driver could use DMA to do the screen updates, but currently writes
|
|
the data to the LCD using the processor instead.
