Re: Asyn support

[Stefen Paul <stefen4114@gmail.com>]

Hi,

I have something more to add ....

I could add asyn record in the VDCT database.

There was no problem till the point of adding asyn records and building (make) the application  

But when I executed st.cmd  (using <app>.exe , on win32 PC), first I got the error "asyn.dll not found".

So I added the path of asyn.dll to the system variable PATH.

Now when I execute st.cmd , I get the following error :

"The procedure entry point WSAPoll could not be located in the dynamic link library WS2_32.dll"

I tried adding the path of this dll to the system PATH but the I keep getting the same error on executing st.cmd

Any Clues about this problem ?

(Note : No such error was seen when I added Calc module for acalcout & scalcout records, I just had to add path of calc.dll to PATH)

Thanks,

Stefen

Hi Stefen,

You are missing one step.  In the exampleApp/Makefile you need to add the lines:

example_DBD += asyn.dbd
example_DBD += drvAsynSerialPort.dbd

Hi,

I’ve  followed these steps trying to include ‘asyn’ record in a win32-x86 EPICS application :

(1) Downloaded asyn4-30 and unzipped in a particular location (epics\modules).

(2) In the configure/RELEASE file of asyn, specified the path EPICS_BASE.

(3) Did the ‘make clean install’ for asyn that completed without error.

(4) Created a win32-x86 application using ‘makeBaseApp –i –t example’.

(5) In the configure/RELEASE file for this app, added the appropriate paths EPICS_BASE and  ASYN.

(6) In the src/MAKEFILE, added <app>_LIBS += asyn

(7) Did the ‘make clean install’ for the application that completed without error.

(8) Opened the default dbd/db combination of the app (<app>.dbd & dbExample1.db) using VDCT.
Now when I try to create a new record, I don’t find the ‘asyn’  in the drop-down list for record type.

Am I missing any step ?

Thanks,
Stefen

Hi Stephen,

I would recommend using the most recent version of asyn. Older versions will also work, but don't have all the bug fixes. It will work with your version of base.

Hi,

Using asyn will make developing a driver easier, but in most cases you can use StreamDevice (a separate install which works with asyn) and you only then need to provide a text based protocol definition file for new devices. See http://www.aps.anl.gov/epics/modules/soft/asyn/ for links to versions of asyn compatible with your EPICS base as well as links to using SteamDevice. If you will be installing other EPICS modules too, you may want to consider the synApps collection https://www1.aps.anl.gov/BCDA/synApps which includes asyn and StreamDevice as well as many other useful EPICS modules

Hi All,

I have downloaded and built epics base 3.14.12.4 for windows, on a PC running winXP.

I wanna use serial COM ports from epics application. I believe I will be needing asyn support to make that happen.

plz suggest which asyn version will work with my epics version, how to integrate asyn in my setup and how to use it in application.

Thanks,
Stefen
