Interesting...
Out of curiosity: what is your use case? Data visualization?

Cheers,

Mostly for educational use.

Now small computers, such as Raspberry Pi, are available on the market.
And we can run EPICS on it to interface with REAL world.

In principle it is possible to run CSS or edm on these computers, I

think it is better to have

light weight enviroment on these computers. So I took "Processing",

which I happend to know.

"Processing" is supported by many artists, who are not technology

oriented people in general, it means "Processing" can be supported by

the beginners in programming as well.

This is a thought in my mind when I started this trial.

    Hello, this is Noboru Yamamoto from J-PARC/KEK, JAPAN.

    I just want report a small software experiment.

    I tested possibility of using EPICS channel access in "Processing"
    environment.
    I found that it is possible to access EPICS data through channel
    access protcol in "Processing".

    First of all, you may not know what "Processing" is.
    According to the web page, https://processing.org/,
    "Processing" is
    "a flexible software sketchbook and a language for learning how to
    code within the context of the visual arts. Since 2001, Processing
    has promoted software literacy within the visual arts and visual
    literacy within technology. There are tens of thousands of students,
    artists, designers, researchers, and hobbyists who use Processing
    for learning and prototyping. "

    Processing IDE is written in Java.  Processing supports few flavours
    of languages, such as Java, Python and javascript.
    When you use Java flavour Processing language, it is possible to use
    your java library in
    the processing sketch as plug-in.
    I took jca/caj jar files and create some fiels/folders to use them
    as a plugin in  Processing.

    Then processing sketch can read( I didn't test write yet) data from
    EPICS database through CA (an example processing sketch is attached).

    It is just resut of a few days of  fiddling codes. If you have any
    interest, please let me know.

    Thank you for your attension.
