Parameters:
Return Value: ERR_OK
int seDisplayFifo(int DevID, BYTE State)
Description:
Parameters:
Return Value: ERR_OK
Disabling the display FIFO will force all display data outputs to zero but horizontal and vertical
sync pulses and panel power supply are still active. As stated earlier, the hardware cursor and ink
layer are not affected by disabling the FIFO.
This function retrieves the default (as set by 1355CFG.EXE) value for the host bus
interface width and returns it in Width.
DevID
Width
This routine turns the display on or off by enabling or disabling the ENABLE bit of
the display device (PANEL, CRT, or SIMULTANEOUS). The Display Mode
setting (LCD, CRT or SIMULTANEOUS) determines which device(s) will be
affected, the default mode is stored in the HAL_STRUCT.
DevID
State
This routine turns the display on or off by enabling or disabling the display FIFO
(the hardware cursor and ink layer are not affected).
To quickly blank the display, use seDisplayFifo() instead of seDisplayEnable().
Enabling and disabling the display FIFO is much faster, allowing full CPU
bandwidth to the display buffer.
DevID
State
- registered device ID
- integer to hold the returned value of the host bus width
- the function completed successfully
- registered device ID
- set to ON or OFF to respectively enable or disable the display
