9.4.2 General HAL Support
S1D13705
X27A-G-002-02
Functions in this group do not fit into any specific category of support. They provide a
miscellaneous range of support for working with the S1D13705
int seGetId(int * pId)
Description:
Parameters:
Return Value: ERR_OK
void seGetHalVersion(const char ** pVersion, const char ** pStatus,
const char **pStatusRevision)
Description:
Parameters:
Return Value: None
Example:
Reads the S1D13705 revision code register to determine the chip product and
revisions. The interpreted value is returned in pID.
pId
Other HAL libraries will return their respective controller IDs upon detection of
their controller.
ERR_UNKNOWN_DEVICE - the HAL was unable to identify the display
controller. Returned when pID returns ID_UNKNOWN.
Retrieves the HAL library version. The return pointers are all to ASCII strings. A
typical return would be: *pVersion == “1.01” (HAL version 1.01),*pStatus == “B”
(The 'B' is the beta designator), *pStatusRevision == “5”. The programmer need
only create pointers of const char type to pass as parameters (see Example below).
pVersion
pStatus
pStatusRevision - Pointer to return the current revision of status.
const char *pVersion, *pStatus, *pStatusRevision;
seGetHalVersion( &pVersion, &pStatus, &pStatusRevision);
- pointer to an integer which will receive the controller ID.
S1D13705 values returned in pID are:
- ID_S1D13705_REV0
- ID_UNKNOWN
- operation completed with no problems
- Pointer to string to return the version in.
- must point to an allocated string of size VER_SIZE
- Pointer to a string to return the release status in.
- must point to an allocated string of size STATUS_SIZE
- must point to an allocated string of size STAT_REV_SIZE
