int seSetBitsPerPixel(int BitsPerPixel)
int seGetBitsPerPixel(int * pBitsPerPixel)
int seGetBytesPerScanline(int * pBytes)
This routine sets the display color depth.
After performing validity checks to ensure the requested video mode can be set the
appropriate registers are changed and the Look-Up Table is set its default values
appropriate to the color depth.
This call is similar to a mode set call on a standard VGA.
BitsPerPixel - desired color depth in bits per pixel.
ERR_FAILED- possible causes for this error include:
1) the desired frame rate may not be attainable with the specified input clock
2) the combination of width, height and color depth may require more memory than
is available on the S1D13705.
This function reads the S1D13705 registers to determine the current color depth and
returns the result in pBitsPerPixel.
pBitsPerPixel - pointer to an integer to receive current color depth.
Determines the number of bytes per scan line of current display mode. It is assumed
that the registers have already been correctly initialized before seGetBytesPer-
Scanline() is called (i.e. after initializing the HAL, setting the Display mode and
adjusting the bits per pixel or other values).
The number of bytes per scanline will include non-displayed bytes if the screen
width is greater the display width, or in Default Portrait Mode.
pBytes
- Valid arguments are: 1, 2, 4, and 8.
- operation completed with no problems
- return values will be: 1, 2, 4, or 8.
- operation completed with no problems
- pointer to an integer to receive the number of bytes per scan line
