Hi Torsten and Yoon,

Yoon’s original message DOES have the asynEnumMask in both the interface mask and the interrupt mask. This is from his original message, I have added red highlighting.

ct08::ct08(const char *portName, const char *IPPortName, const char *outputString)

: asynPortDriver(portName,

1, /* maxAddr */

asynOctetMask | asynInt32Mask | asynFloat64Mask |asynFloat64ArrayMask |asynEnumMask |asynDrvUserMask,/* Interface mask */

asynOctetMask | asynInt32Mask | asynFloat64Mask |asynFloat64ArrayMask |asynEnumMask |asynDrvUserMask, /* Interrupt mask */

0,

ASYN_CANBLOCK, /* asynFlags. This driver does block and it is not multi-device*/

1, /* Autoconnect */

0, /* Default priority */

0) /* Default stack size*/

So I don’t understand why that message is appearing.

Yoon, please send the output of this command after the IOC has booted:

asynReport 3 PORT1

That will show what interfaces are configured to do callbacks.

Mark

I think you are missing this mask:

| asynEnumMask,

here:

ct08::ct08(const char *portName, const char *IPPortName, const char *outputString)

: asynPortDriver(portName,

1, /* maxAddr */

asynOctetMask | asynInt32Mask | asynFloat64Mask |asynFloat64ArrayMask |asynEnumMask |asynDrvUserMask,/* Interface mask */

asynOctetMask | asynInt32Mask | asynFloat64Mask |asynFloat64ArrayMask |asynEnumMask |asynDrvUserMask, /* Interrupt mask */

0,

ASYN_CANBLOCK, /* asynFlags. This driver does block and it is not multi-device*/

1, /* Autoconnect */

0, /* Default priority */

0) /* Default stack size*/

Subject: A question on asyn application

Hello everyone,

I am using the asyn module to write a device IOC. I want to set the SCAN field as Intr I/O to adapt to the application requirement.

The db file is like this:

record(stringin,"$(P)Ver")

{

field(DESC,"Firmware version")

field(DTYP, "asynOctetRead")

field(INP, "@asyn($(PORT),$(ADDR)) VERSION")

field(SCAN,"I/O Intr")

}

record(stringin,"$(P)Mod")

{

field(DESC,"Get counter mod")

field(DTYP, "asynOctetRead")

field(INP, "@asyn($(PORT),$(ADDR)) MOD")

field(SCAN,"I/O Intr")

}

record(stringout,"$(P)Reboot")

{

field(DESC,"Reboot Device")

field(DTYP,"asynOctetWrite")

field(OUT,"@asyn($(PORT),$(ADDR))REBOOT")

field(VAL, "REST")

}

record(stringin, "$(P)GateInStatus")

{

field(DESC,"DS:AlwaysON/EN:Need Input")

field(DTYP,"asynOctetRead")

field(INP,"@asyn($(PORT),$(ADDR)) GATEINSTATUS")

field(SCAN,"I/O Intr")

}

record(longin,"$(P)Count07")

{

field(DESC,"Counter 07")

field(DTYP, "asynInt32")

field(INP, "@asyn($(PORT),$(ADDR)) COUNT07")

field(SCAN,"I/O Intr")

}

... ...

When I run the st.cmd file, it prompt: ”initCommon enum registerInterruptUser asynManager: getInterruptPvt Driver does not support interrupts on intterface asynEnum”. All the test-error picture, st.cmd and the complete .cpp files are attatched. I don't know where the problem is and how to correct it. Maybe a polling function is necessary in the .cpp file when the SCAN filed is "I/O Intr", and the write or read functions should be called in the polling function?

Looking forward to your feedback. Thank you very much.

Best wishes,

Yoon
