Enable dual framebuffer for LCDIF peripheral. Two framebuffers
|

|
|
will be allocated, and switched between for each frame.
|

|
|
Note that for partial display updates, the prior framebuffer must
|
||
|
|
be copied into the next one. This can have significant performance
|
||
|

impact.

Use external memory for framebuffer. Configures the LCDIF to write
|
||
|
|
framebuffer data to a memory mapped external device.
|
||
|
|
|
||
|
|
Note that no specific linker section is used for this framebuffer, so
|
||
|
|
if the application uses the external memory for other purposes, care
|
||
|
|
should be taken to ensure that the memory allocated for the LCDIF
|
||
|
|
does not overlap with other data. Each allocated LCDIF buffer will
|
||
|
|
utilize (lcd_width * lcd_height * bytes_per_pixel) bytes of data,
|
||
|
|
and buffers will be allocated contiguously.
