Note
The following section describes the HAL functions dealing with S1D13705 initialization.
Typically a programmer has only to concern themselves with calls to seRegisterDevice()
and seSetInit().
Description:
Parameters:
Return Value: ERR_OK
Description:
Parameters:
Return Value: ERR_OK
int seRegisterDevice(const LPHAL_STRUC lpHalInfo)
seSetInit()
seRegisterDevice() MUST be called before any other HAL functions.
No S1D13705 registers are changed by calling seRegisterDevice().
After this call the Look-Up Table will be set to a default state appropriate to the display
type.
Unlike S1D1350x HAL versions, this function does not call seSetDisplayMode as this
function does not exist in the 13705 HAL.
This function registers the S1D13705 device parameters with the HAL library. The
device parameters include address range, register values, desired frame rate, etc.,
and are stored in the HAL_STRUCT structure pointed to by lpHalInfo. Additionally
this routine allocates system memory as address space for accessing registers and the
display buffer.
lpHalInfo
ERR_UNKNOWN_DEVICE - the HAL was unable to find an S1D13705.
Configures the S1D13705 for operation. This function sets all the S1D13705 control
registers to their default values.
Initialization of the S1D13705 is a two step process to accommodate those programs
(e.g. 13705PLAY.EXE) which do not initialize the S1D13705 on start-up.
None
- pointer to HAL_STRUCT information structure
- operation completed with no problems
- operation completed with no problems
