Dear community,
I would like to learn about the usage of epics interrupt. I found an example routine called `int32Driver` (asyn/iocBoot/ioctestEpics/st.cmd and asyn/testEpicsApp/src). In the `st.cmd` script, there is a record instance that I want to use to run an interrupt because it has `SCAN=I/O Intr`. Here is the example record instance: record(ai,"asyndevAiInt32A0") { field(SCAN,"I/O Intr") field(DTYP,"asynInt32") field(INP,"@asyn( int32 , 0 , 1.0) ") field(LINR,"LINEAR") field(EGUF,"100.0") field(EGUL,"-100.0") field(PREC,"3") } After running `epics` using the above command, I tried to read the data generated by the interrupt using `caget asyndevAiInt32A0`. However, the return value of `caget` did not change. How can I make `asyndevAiInt32A0` generate a read data interrupt to software simulate a hardware interrupt that produces new data?
