Hello Vikram,

 

There is a C++ class asynPortDriver, which makes life a lot easier.

 

Mark Rivers has given talks about it and written very informative documentation. Examples of asynFloat64Array and asynInt32Array implementation would be much the same.

https://www.google.co.uk/url?sa=t&rct=j&q=&esrc=s&source=web&cd=5&ved=0CFEQFjAE&url="">

 

A full class reference can be found here: It covers asynInt32Array.

 

http://www.aps.anl.gov/epics/modules/soft/asyn/R4-20/asynDoxygenHTML/classasyn_port_driver.html

 

I hope this helps.

 

Regards,

Ian

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
