Dear MESA specialists.
Does it's possible to use your boards in free programming, to get some examples to interface your boards, I/O, ethernet boards, etc, using simple programming (C or python) language without linuxcnc. There is also interesting mathematical program MATLAB, that get interfacing to other similar boards.

I thing under junction of Matlab and your mesa and creating some PLC-PC.

Yes, in fact LinuxCNC is only a small part of the Mesa market as far as I know.

I'm a little surprised with a lack of acitivity for this topic. I quess that it's possible but how to do that? It seems that mesa specialists keep silence.

As I know texas instruments has it's boards for such application and they are has docs for connecting to Labview program.
I quess, Mesa has the same functionality.
I forgot to mension, Matlab has python interface and c++ also can be connected to it.

Actually if you read the relevant Mesa manuals you will find that they are indeed very generic bits of hardware that are quite hardware and software agnostic. Now if you are looking for a ready rolled solution then using the LCNC drivers and GUIs is the path of least resistance.

most here are ordanary users
so they stay with the Gui presented
and there are lots of it right now
noone wants to do real programming
the Main stream dident even got a view at the Config code
so they use the configurator
and it is a long way to go with mathlab to a runing mashine
so only for individuelll users ma be interesting to form there needs
and ofcause the arduino and android CNC community is very up to the Java Mathlab GUI

It's a pity, but I refer myself to "ordinary user" that know python or C++ on lowest basic level.

But I make programs for PLC (and for Matlab few years ago). I like Matlab for it powerful mathematical and visual funcitions.
Few years ago I had problem with connecting Matlab to real world with IO, then I find that it's possible to connect throug ethernet PLC and Matlab, but now I think better is to use special PC boards instead of PLC (that give big latency).
My job is to repair automation of machines and I found in one Texas Insruments boards that used for purpose I need. As for my mind, It's much easier for me to use MESA board instead of TI ( in logistic and price dimensions), also If something goes wrong with my "project", I can this boards use for CNC machine.

If somebody could supply me with some datasheets for this topic, it would be wery nice.

All of the Mesa manuals and firmware source code is available on their web site.

Ok, thanks for that. A little I've understood.
For example manual for 5i25, page 13, I must get, how to interface SPI port from my program, and it will reach what I need.

"DATA REGISTER at offset 0x74 from 5I25 base address" means,
that if adress of 5i25 base is 0x12( for example), that
D0 register will be at 0x74+0x12= 0x86 adress?

I've read that program, but it still black hole for me, how to use it I don't wonder.
may be it's better for me not to dive into such deeps as such programing(((
