Function
Note
The following section describes the HAL functions dealing with initialization of the SED1355.
Typically a programmer will only use the calls seRegisterDevice() and seSetInit().
int seRegisterDevice(const LPHAL_STRUC lpHalInfo, int * pDevice)
Description:
Parameters:
Return Value: ERR_OK
Example:
No SED1355 registers are changed by calling seRegisterDevice().
seRegisterDevice() MUST be called before any other HAL functions.
Initialize the Ink layer variables and registers; enable ink layer
Enables the Ink layer
Disables the Ink layer
Determine the offset of the first byte of Ink layer memory in the display buffer (landscape
mode)
Sets the specified Ink layer color entry (0-1) to color
Draw one pixel into the Ink layer memory at (x,y) from top left corner of cursor
Draw a line into the Ink layer memory from (x1,y1) to (x2,y2) in specified color
Draw a rectangle into the Ink layer memory from (x1,y1) to (x2,y2) in specified color
Draw an ellipse into the Ink layer memory centered at (xc,yc) of radius (xr,yr) in specified
color
Draw a circle into the Ink layer memory centered at (x,y) of radius r in specified color
Control SED1355 SW suspend mode (enable/disable)
Control SED1355 HW suspend mode (enable/disable)
This function registers the SED1355 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
pDevice
seRegisterDevice( &HalInfo, &DeviceId);

- pointer to HAL_STRUCT information structure as defined in
appcfg.h (HalInfo)
- pointer to the integer to receive the device ID
- operation completed with no problems
