With LCD driver all calculation will be performed on RGB888 and the hardware/OS can display from our 24bit framebuffer. It is not yet as performance optimized as the existing drivers but should be good enough.The vast number of small changes is due to the fact that fb_data can be a struct type now, while most of the code expected a scalar type. lcd-as-memframe ASM code does not work with 24bit currently so the with 24bit it enforces the generic C code. All plugins are ported over. Except for rockpaint. It uses so much memory that it wouldnt fit into the 512k plugin buffer anymore (patches welcome).

/* Frame buffer stride
|
|
*
|
|
* Stride describes the amount that you need to increment to get to the next
|
|
* line. For screens that have the pixels in contiguous horizontal strips
|
|
* stride should be equal to the image width.
|
|
*
|
|
* For example, if the screen pixels are layed out as follows:
|
|
*
|
|
* width0 width1 width2 widthX-1
|
|
* ------ ------ ------ ------------------ --------
|
|
* height0 | pixel0 pixel1 pixel2 ----------------> pixelX-1
|
|
* height1 | pixelX
|
|
*
|
|
* then you need to add X pixels to get to the next line. (the next line
|
|
* in this case is height1).
|
|
*
|
|
* Similarly, if the screen has the pixels in contiguous vertical strips
|
|
* the stride would be equal to the image height.
|
|
*
|
|
* For example if the screen pixels are layed out as follows:
|
|
*
|
|
* width0 width1
|
|
* ------ ------
|
|
* height0 | pixel0 pixelY
|
|
* height1 | pixel1
|
|
* height2 | pixel2
|
|
* | | |
|
|
* \|/ | \|/
|
|
* heightY-1 | pixelY-1
|
|
*
|
|
* then you would need to add Y pixels to get to the next line (the next
|
|
* line in this case is from width0 to width1).
|
|
*
|
|
* The remote might have a different stride than the main screen so the screen
|
|
* number needs to be passed to the STRIDE macro so that the appropriate height
|
|
* or width can be passed to the lcd_bitmap, or lcd_remote_bitmap calls.
|
|
*
|
|
* STRIDE_REMOTE and STRIDE_MAIN should never be used when it is not clear whether
|
|
* lcd_remote_bitmap calls or lcd_bitmap calls are being made (for example the
|
|
* screens api).
|
|
*
|
|
* Screen should always use the screen_type enum that is at the top of this
|
|
* header.
