RE: User of AsynInt32Array

If you search the asyn module for .db files containing the string “Array” you will find the following examples:

 

corvette:~/devel/asyn>find . -name '*.db' -exec grep -H Array {} \;

./db/testAsynPortDriver.db:    field(DTYP, "asynFloat64ArrayIn")

./db/testAsynPortDriver.db:    field(DTYP, "asynFloat64ArrayIn")

./db/testErrors.db:#  Records that use devAsynXXXArray                               #

./db/testErrors.db:    field(DTYP, "asynInt8ArrayIn")

./db/testErrors.db:    field(DTYP, "asynInt16ArrayIn")

./db/testErrors.db:    field(DTYP, "asynInt32ArrayIn")

./db/testErrors.db:    field(DTYP, "asynFloat32ArrayIn")

./db/testErrors.db:    field(DTYP, "asynFloat64ArrayIn")

./testErrorsApp/Db/testErrors.db:#  Records that use devAsynXXXArray                               #

./testErrorsApp/Db/testErrors.db:    field(DTYP, "asynInt8ArrayIn")

./testErrorsApp/Db/testErrors.db:    field(DTYP, "asynInt16ArrayIn")

./testErrorsApp/Db/testErrors.db:    field(DTYP, "asynInt32ArrayIn")

./testErrorsApp/Db/testErrors.db:    field(DTYP, "asynFloat32ArrayIn")

./testErrorsApp/Db/testErrors.db:    field(DTYP, "asynFloat64ArrayIn")

./testAsynPortDriverApp/Db/testAsynPortDriver.db:    field(DTYP, "asynFloat64ArrayIn")

./testAsynPortDriverApp/Db/testAsynPortDriver.db:    field(DTYP, "asynFloat64ArrayIn")

 

So testErrorsApp/Db has examples of all of the asynXXXArray device support, and testAsynPortDriver has an example of asynFloat64Array, which is just like asynInt32Array but with a different data type.

 

asyn/devEpics/devAsynInt32Array.dbd contains the strings that you must put in the DTYP field of your waveform records:

 

corvette:asyn/asyn/devEpics>more devAsynInt32Array.dbd

device(waveform,INST_IO,asynInt32ArrayWfIn,"asynInt32ArrayIn")

device(waveform,INST_IO,asynInt32ArrayWfOut,"asynInt32ArrayOut")

Hello all,

       I want to know about how to use asynInt32Array,

Actually on AsynDriver.pdf i could find few information about it.    

 

typedef struct asynXXXArray {

asynStatus (*write)(void *drvPvt, asynUser *pasynUser, epicsXXX *value, size_t nelements);

asynStatus (*read)(void *drvPvt, asynUser *pasynUser, epicsXXX *value, size_t nelements, size_t *nIn);

asynStatus (*registerInterruptUser)(void *drvPvt, asynUser *pasynUser, interruptCallbackXXXArray callback,void *userPvt,void **registrarPvt);

asynStatus (*cancelInterruptUser)(void *drvPvt, asynUser *pasynUser, void *registrarPvt);

} asynXXXArray;

 

 

 

but not detail information how  write and read methods can be used and what should me my db file content for read and write operation.

 

Like provided for asynInt32

record(ai,"aiInt32") {

                        field(SCAN,"I/O Intr")

                        field(DTYP,"asynInt32")

                        field(INP,"@asyn($(port),$(addr))")

                        field(EGUF,"10.0")

                        field(EGUL,"-10.0")

                        field(PREC,"3")

            }

 

where can i find the detail user manual / application developer guide?

 

Thanks
