11.5.2 Advanced HAL Functions
Programming Notes and Examples
Issue Date: 99/04/27
Note
int seDelay(int DevID, DWORD Seconds)
Description:
Parameters:
Return Value: ERR_OK
int seGetLinearDispAddr(int device, DWORD * pDispLogicalAddr)
Description:
Parameter:
Return Value: ERR_OK
Advanced HAL functions include the functions to support split and virtual screen operations and are
the same features that were described in the section on advanced programming techniques.
int seSplitInit(int DevID, DWORD Scrn1Addr, DWORD Scrn2Addr)
Description:
Parameters:
Return Value: ERR_OK
It is assumed that the system has been properly initialized prior to calling seSplitInit().
This function will delay for the number of seconds given in Seconds before
returning to the caller.
This function was originally intended for non-PC platforms. Because information on
how to access the timers was not always immediately available, we use the frame
rate for timing calculations. The SED1355 registers must be initialized for this
function to work correctly.
The PC platform version of seDelay() calls the C timing functions and is therefore
independent of the register settings.
DevID
Seconds
ERR_FAILED- returned only on non-PC platforms when the SED1355 registers
have not been initialized.
Determines the logical address of the start of the display buffer. This address may
be used in programs for direct control over the display buffer.
device
pDispLogicalAddr - logical address is returned in this variable.
This function prepares the system for split screen operation. In order for split screen
to function the starting address in the display buffer for the upper portion (screen 1),
and the lower portion (screen 2) must be specified. Screen 1 is always displayed
above screen 2 on the display regardless of the location of their respective starting
addresses.
DevID
Scrn1Addr - offset in display buffer, in bytes, to the start of screen 1
Scrn2Addr - offset in display buffer, in bytes, to the start of screen 2
