hello, since there is no default configuration for 7i96s+7i77 in pnccfg, I'm trying to use mesact, but I get an error, I can't enter values ​​in the specified fields at all. thanks

Colleagues, does this apply for version 2.8.4?

Yes this is my goal, everything on a same board.
IC-NV part is not easy but one from PEdpex is working so I should use the same.
There is not much chip that can do this as good as IC-NV so I might stick to this one.
And STM32F4 works good for encoders so it should be a good match.
I will try to start from your E7000 then thank you

I want to install samba, but apt install samba gives "Package 'samba' has no installation candidate", I did apt update but it didn't help. I checked repositories and there is only linuxcnc.org. Should I have also Debian repositories or not? How to install samba?

Also do I need: "download.opensuse.org/repositories/science:/EtherLab/Debian_12/"? What is it for? It gives an error on apt update:
"Get:1 download.opensuse.org/repositories/science:/EtherLab/Debian_12 ./ InRelease [1,575 B]

I found Pedpex's work, awesome.
Maybe that is what you have in mind, but I would put his circuitry on the same board as ethercat
to have it neatly packaged.
One thought I got is if one can skip the quadrature part in some way. Are there sin cos chips
that can deliver a value over spi or i2c for example?
The built-in quadrature encoder in stm32f4 can read with at least 3 MHz so maybe not a big problem.
I have code to extend numbers over the 16-bit and 32-bit boundary.
Code for encoder counting is in E3000 project. 
Best to base HW on E7000 project, clear out pins and I2C and add encoder inputs.
 

IC-NV are here for the conversion, not easy to setup but Pedpex, a member from the forum did the stuff.
My goal is to merge his project to yours basically.

I will prepare all the work environment and when the schematic will be done or almost I will open a thread. Maybe i should start with a prototype PCB from you as I already get a pcb from pedpex and when everything is running, I do the merge

I Installed the WIll have a look at it.

Best regards

Here is a screenshot from the Latency Test of the old configuration. Only for the Kernel-Infos.
The latency was horrible at this time (without irq-optimisation at this time)
   

I don't know much about cos sin. The whole processor is available for you to do all sorts of processing.
The ethercat part is the easy one I would say.
Every cycle you calculate a new encoder value, set a pdo variable and the soes library does the rest.

Edit. But I checked quickly. So you need to take in two analogue signals and calculate the phase angle.
Absolutely doable, could be a nice application.
Start a project thread and I'll give you a hand with the ethercat stuff.

Edit 2. The ADCs on STM32F4 are only 12-bit, you may need 16-bit ADC for this. Another processor? 
External 16-bit ADC unit?

Edit 3. IC-NV instead of ADCs of course.

Hi,

I also did a fresh installation on a DELL Optiplex 3060 Micro PC (RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller)
Everything incl. IRQ-Optimizing (Latency) works fine, but i also run into this error "Error finishing read" with my MESA 7i96s.


In my old installation (at this PC) i run the 3.6.0 rt11 Kernel and did not have this problems, so i think, last time i updated it for the same reason. Sadly i don`t know how to do this update again.
Is there an easy way only updating the kernel?
(Sorry but I`m not in the Linux-Space, so its a little hard for me)

Thanks a lot
Jens

Buongiorno, sono un nuovo iscritto di appena 78 anni, appassionato di elettronica e meccanica.
Ho bisogno di inserire le funzioni Pausa e Resume per poter fermare gli assi x e y mentre l'asse z si trova in un certo punto, e riprendere il loro movimento quando l'asse z raggiunge il punto successivo (tutto controllato da fotoaccoppiatori). so che è possibile, ma purtroppo la mia competenza nel linguaggio di Linuxcnc è limitata.
Grazie.

I use ecam, as soon as I can I'll send you mine, it works well.

Hello,
Thank you for your reply
Ideally, I would like to integrate the project from PedPex which is a COS SIN converter (with IC-NV chip) for heidenhain glass scale directly as an ethercat module. It would receive COS SIN signal, convert it to quadrature, read by the STM32 then sent to Ethercat.
But this is a little bit out of my league knowledge wise, even if you did most of the job regarding ethercat and Pedpex most of the job regarding COS SIN conversion

I am currently running LINUXCNC - 2.9.7
6.1.0-30-rt-amd64 #1 SMP PREEMPT_RT Debian 6.1.124-1 (2025-01-12) x86_64 GNU/Linux
This was upgraded, re-installed and built from source after my initial installation. I installed Mint on another drive, but the OS took forever to boot, and just felt sluggish.
My main aim is to get something functional and stable going ASAP. I can always make it nice later.

Actually when you know where to look, the documentation runs to hundreds of not thousands  of pages.
setting up a gantry machine requires joint axes and is covered in the  homing docs. linuxcnc.org/docs/stable/html/config/ini-homing.html
You usually need to read that link about 10 times before it makes sense.
Briefly you need a home switch on each joint (eg a joint is a motor). When set up right with negative  home_sequence, the first side of the gantry stops and waits for the other side to catch up before moving in unison. Gantry Squareness is adjusted by setting the home_offset in the ini file
