Ethercat HAL driver

Hi,

what do you want to achieve with the driver?

how should the hal interface be designed? do you want to have an "virtual" com port for the device.
or simple rx and tx buffer arrays, with correspondending transmit and receive bits?

Hello again db1981 :lol:

I would love to have a virtual com port for the device, but i think either way i would make it work with my device

Edit:
On windows i can see that twincat has a Virtual Com port application.
How would one achieve similar application with linuxcnc ethercat ?

Driver for EL6021 would be nice for controlling servos over Beckhoff Ethercat.
I think it's not critical if its implemented with rx and tx buffers or with linux virtual com port.
Maybe with buffers its easier to handle inside hal files by having read/write interface similar to pins.

I am not sure where to share stuff like this, but i tried my hand at writing a driver for EL3004 analog input 4 channels, 12 bits, single ended, +/-10V

This my first encounter with writing a driver, so let me know how it might be improved.

Hi Stormhold,

I checked your code..

There is something i noticed at compile time. If the project is loaded in Qt, you can see if everything is ok.
In this case something was not found.


Solved with :


Did you mention this before during halcompile?

Ok qt halcompile project attached, your driver is attached, it works without update status i suggest..
github.com/grotius-cnc/Linux-Embedded/re...ile-qt-el3004.tar.gz

To open the project, in qt load the file : qt-test.creator , then check the howto-pictures in the archive.

How very embarrassing... a misspelling :blush: :sick: a new file is attached

I don't quite understand the 'how to pictures', am i supposed to write a test.c file? or was there supposed to be one in the tarball?

I have no experience with qt creator, but it seems nice to know :lol:
