int seInitHal(void)
Description:
Parameters:
Return Value: ERR_OK
seSetInit(int DevID)
Description:
Parameters:
Return Value: ERR_OK
This function calls seSetDisplayMode() and uses the configuration designated to be the default
by 1355CFG.EXE (wDefaultMode in HAL_STRUCT). The programmer could call
seSetDisplayMode() directly allowing the selection of any DisplayMode configuration along
with the options of clearing memory and blanking the display (DISP_FIFO_OFF).
It is strongly recommended that the programmer call either seSetInit() or seSetDisplayMode()
after seRegisterDevice() before calling any other HAL functions. If not, the programmer must
manually disable hardware suspend and enable the host interface before accessing the registers
This function initializes the variables used by the HAL library. This function or
seRegisterDevice() must be called once when an application starts.
Normally programmers do not have to concern themselves with seInitHal(). On PC
platforms, seRegisterDevice() automatically calls seInitHal(). Consecutive calls to
seRegisterDevice() will not call seInitHal() again. On non-PC platforms the start-up
code, supplied by Epson, will call seInitHal().However, if support code for a new
operating platform is written the programmer must ensure that seInitHAL is called
prior to calling other HAL functions.
None
This routine sets the SED1355 registers for operation using the default settings.
Initialization of the SED1355 is a two step process consisting of initializing the HAL
(seInitHal) and initializing the SED1355 registers (seSetInit). Unlike the HAL the
registers do not necessarily require initialization at program startup and may be
initialized as needed (e.g. 1355PLAY.EXE).
DevID
ERR_FAILED- unable to complete operation. Occurs as a result an invalid register
in the HAL_STRUCT.
- operation completed with no problems
- registered device ID (acquired in seRegisterDevice)
- operation completed with no problems
