Note
int seSetDisplayMode(int DevID, int DisplayMode, int flags)
Description:
Parameters:
Return Value: ERR_OK
See Also:
Example:
See note from seSetInit().
This routine sets the SED1355 registers according to the values contained in the
HAL_STRUCT register section.
aspects of chip operation are set with this call, including loading default values into
the color Look-Up Tables (LUTs).
DevID
DisplayMode- the HAL_STRUCT register set to use:
flags
ERR_FAILED - unable to complete operation. Occurs as a result of an invalid
seSetDisplayMode(DevID, DISP_MODE_LCD, CLEAR_MEM |
DISP_FIFO_OFF);
The above example will initialize for the LCD, and then clear display buffer memory
and blank the screen. The advantage to this approach is that afterwards the appli-
cation can write to the display without showing the image until memory is
completely updated; the application would then call seDisplayFIFO(DevID, ON).
Setting all the registers means that timing, display surface dimensions, and all other
seDisplayFifo() - for enabling/disabling the FIFO.
- a valid registered device ID
- Can be set to one or more flags. Each flag added by using the
- no problems encountered
register in the HAL_STRUCT.
DISP_MODE_LCD,
DISP_MODE_CRT, or
DISP_MODE_SIMULTANEOUS
logical OR command. Do not add mutually exclusive flags.
Flags can be set to 0 to use defaults.
DONT_CLEAR_MEM (default) - do not clear memory
CLEAR_MEM - clear display buffer memory
DISP_FIFO_OFF - turn off display FIFO
DISP_FIFO_ON (default) - turn on display FIFO
(blank screen except for cursor or ink layer)
