Hi,
I hope someone can help - I am sure I am missing something obvious but so far I haven't been able to fix the following issue.
I am writing an IVI-C driver in CVI for an IviFgen and the generator does not support the IviFgenArbSeq capability so I want to remove this from the driver.
I have deleted the "IviFgenArbSeq," line from the below
/*=CHANGE:===============================================================*
Set the group capabilities attribute, Remove the extension groups
this driver does not support, and add additional code to dynamically
determine how the presence of specific instrument options may affect
this attribute.
*============================================================END=CHANGE=*/
checkErr( Ivi_SetAttributeViString (vi, "", TG5011_ATTR_GROUP_CAPABILITIES, 0,
"IviFgenBase,"
"IviFgenStdFunc,"
"IviFgenArbWfm,"
"IviFgenArbFrequency,"
"IviFgenArbSeq,"
"IviFgenTrigger,"
"IviFgenInternalTrigger,"
"IviFgenSoftwareTrigger,"
"IviFgenBurst,"
"IviFgenModulateAM,"
"IviFgenModulateFM"));
and deleted the following
/*=CHANGE:=============================================================*
Define TG5011_VAL_MAX_SEQUENCES below to the
maximum number of arbitrary sequences your function generator
supports. If your function generator does not support arbitrary
sequences, delete these macros.
*==========================================================END=CHANGE=*/
#define TG5011_VAL_MAX_SEQUENCES (10L)
#define TG5011_VAL_FIRST_SEQUENCE_HANDLE (20000L)
#define TG5011_VAL_LAST_SEQUENCE_HANDLE (TG5011_VAL_FIRST_SEQUENCE_HANDLE + TG5011_VAL_MAX_SEQUENCES - 1L)
#define TG5011_SEQ_HANDLE_FROM_INDEX(y) (TG5011_VAL_FIRST_SEQUENCE_HANDLE + y)
#define TG5011_SEQ_INDEX_FROM_HANDLE(y) (TG5011_VAL_FIRST_SEQUENCE_HANDLE)
Naturally this leads to several compilation errors which I think I have cleaned up by deleting all the functions relating to arb sequencing and I also deleted the attributes in the attribute editor related to sequencing so that the driver now compiles OK.
My question is that when I test the driver with the "Test Specific IVI Driver" (under the Tools menu) I get Compliance errors for arb sequencing. The errors tell me that arb sequencing attributes and functions have not been implemented. But when I run a Compliance check for other vendors fgen drivers (that also do not support sequencing) then I simply get a nice message saying that sequencing has not been implemented - Not an error.
So there must be a way of building into the dll the fact that I have chosen not to implement the capability rather than the functions/attributes are all missing.
Thanks,
Phil
