RE: Cpp code not recognizing asyn parameter

[Mark Rivers via Tech-talk <tech-talk at aps.anl.gov>]

Hi Marco,

 

Did you set the mask for the asynInt32 interface in the constructor for you driver?

 

Please send the complete output when the IOC boots with your driver.  There may be an error message there.

 

Also send the output of this command at the IOC prompt:

 

asynReport 10

 

Mark

Subject: Cpp code not recognizing asyn parameter

 

Hello all. Im trying to use the asyn module to associate the value of a PV to the value of a variable inside my cpp code.

The PV is defined as:

record(mbbo, "$(P)$(BE)DynamicRange"){

    field(DTYP, "asynInt32")

    field(ONVL, "1")

    field(ONST, "Full Dynamic Range")

    field(ZRVL, "0")

    field(ZRST, "Default")

    field(OUT,  "@asyn($(PORT),$(ADDR=0),$(TIMEOUT=1))DYNAMIC_RANGE")

}

In my header file i have:

#define DynamicRangeString            "DYNAMIC_RANGE"

int DynamicRangeString_;

and inside my .cpp:

createParam(DynamicRangeString,             asynParamInt32,   &DynamicRangeString_);

asynStatus Mobipix::writeInt32(asynUser *pasynUser, epicsInt32 value)
{

(...)

printf("test");

}

When i dbpf into other asyn mbbo records that come from ADBase.template, such as "$(P)$(R)FrameType", the ioc shell prints the test message. When i dbpf into my DynamicRange PV nothing happens.

What am i missing?

Thanks for the help,

Marco
