RE: How to remove stdout from caput command

[Mark Rivers via Tech-talk <tech-talk@aps.anl.gov>]

Hi Erwann,

 

To use pyepics:

 

At OS shell:

pip install pyepics

 

In your Python code:

    from epics import caput

    caput(“CODES/TL1_MANIP1/ER_DCH_PosRqst__0 " + str(a) , wait=False)

Hi Erwann,

 

Why not use PyEpics to do the caput equivalent, rather than a system call?

Hello,

 

I use python code to write variable values. Running the code, I observe all stdout, but is it possible to disable them ?

 

Code Example :

 

---------------------------------------------------------------------------------------------------------------------

if (gap > 0 and sleep > 0) :

    for i in range (int(step)):

        os.system("caput CODES/TL1_MANIP1/ER_DCH_PosRqst__0 " + str(a) + "wait=False")

        a = a + c

        time.sleep(sleep)

---------------------------------------------------------------------------------------------------------------------

 

The code returns :

 

---------------------------------------------------------------------------------------------------------------------

Old_value …….

New_value ……

Etc…

---------------------------------------------------------------------------------------------------------------------

 

It is that “Old_value” and “New_value” that I want disabled.

 

Many Thanks.
