buffer is 128 * 96 / 2 = 6Kb. If this is defined, then the driver
|
||||
will be fully functional. If not, then it will have the following
|
||||
limitations:
|
||||
|
||||
|
||||
Reading graphics memory cannot be supported, and
|
||||
|
||||
|
||||
All pixel writes must be aligned to byte boundaries.
|
||||
The latter limitation effectively reduces the 128x96 disply to 64x96.

Build in some non-standard, custom drawing interfaces for the RA8875

including the following: ra8875_drawrectangle(), ra8875_drawline(),

ra8875_drawtriangle(), and ra8875_drawcircle(). NOTE that these

will not be accessible by applications in protected or kernel build

configurations.
|

NOTE: The non-standard ra8875_clear(), ra8875_drawrectangle(),
|

ra8875_drawline() interfaces are always built and available for use
|
||||
because within the OS because these are used internally by the

driver anyway.
