S1D13705 Programming Notes and Examples
X27A-G-002-03 Issue Date: 02/01/22
9.4.2 General HAL Support
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: Reads the S1D13705 revision code register to determine the chip product and
revisions. The interpreted value is returned in pID.
Parameters: pId - pointer to an integer which will receive the controller ID.
S1D13705 values returned in pID are:
- ID_S1D13705_REV0
- ID_UNKNOWN
Other HAL libraries will return their respective controller IDs upon detection of
their controller.
Return Value: ERR_OK - operation completed with no problems
ERR_UNKNOWN_DEVICE - the HAL was unable to identify the display
controller. Returned when pID returns ID_UNKNOWN.
void seGetHalVersion(const char ** pVersion, const char ** pStatus,
const char **pStatusRevision)
Description: 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).
Parameters: pVersion - Pointer to string to return the version in.
- must point to an allocated string of size VER_SIZE
pStatus - Pointer to a string to return the release status in.
- must point to an allocated string of size STATUS_SIZE
pStatusRevision - Pointer to return the current revision of status.
- must point to an allocated string of size STAT_REV_SIZE
Return Value: None
Example: const char *pVersion, *pStatus, *pStatusRevision;
seGetHalVersion( &pVersion, &pStatus, &pStatusRevision);
