Arduino PySerial USB Connection

[prrvchr]

Hi all,

I just commit a new version:
- Qt QThread in place of Python Threading. Now no need of Threading python library. All library needed is in the Workbench...
- Make like a plugin for the TinyG2 card.driver. A generic driver is provided but without file upload.
- Embed some QSemaphore for the management of free buffers on the TinyG2 card driver.


if people are ready to experiment, they are welcome ...
I have no way to test on Windows and Mac OSX ...

Thank you for experimenters

Hi all,

I just pushed a new version...

https://github.com/prrvchr/USBTerminal

Now we have position feed back like you can see on the screenshot...

QThread seems to be much better integrated in FreeCAD.
I am pleasantly surprised with the result.

Looking for volunteers to do some tests, I do not have the possibility on Windows and OSX.

Thank you in advance...

Hello,
With the last update, i can connect to GRBL shield.

Hi Xav-83,

I just push a new version on GitHub, and I hope it will work well...

You can make test with the DefaultDriver on the "loop://" port... this is the first test... and easy it's now the default configuration!!!
After configuring your port accordingly, always with the DefaultDriver test a Terminal connection. You can not test file upload the DefaultDriver don't have...

By cons I do not test with Grbl card, which differs from the TinyG2 card?
In fact, I do not think the Grbl card is Dual End Point (you can see like two serial port on connection)...
But IMO, it is possible to develop quite easily a driver for the Grbl card... But I need more information...

Edit: Document object have changed (many times...), alway restart from scratch!!!

I give some screenshot of last version...

first PySerial properties monitor (read only at this time...)

Same thing, for TinyG2 card, you can see how many properties... (soon editable)

This is starting to look really good! Keep it coming. I guess I am going to have to break down and get some Arduino hardware to start testing this out.

Hi,

You can make test with the DefaultDriver on the "loop://" port...

For the first test in "loop: // ..." I have to get the port? in my case: / dev / ttyACM1?
when I selects my port / dev / ttyACM1 in "ports", "port" (with loop) changes directly.

after configuring your port accordingly, always with the "DefaultDriver.py" test a Terminal connection.

I connect and I can even go to the command terminal (M3, M5, G28 ....) the machine moves ^^ is excelent

I did the same test with the plugin "TinyG2plugin.py" I also happen to login.
and the machine also moves.

unfortunately I do not really know the differences between TinyG and GrblShield
what do you need to develop the driver?

it is expected to be able to control the manual machine to place the tool to his "origine" piece?

nice work, I expected after impatiently.

Hi,

when I selects my port / dev / ttyACM1 in "ports", "port" (with loop) changes directly

Ports is just an help for not tapping the Port name manually... But in fact you can put anything in Port but it's not sure that you arrive to connect...
We can use some keyword recognized by PySerial like: loop:// or hwgrep:// (loop:// is just a pseudo port for testing PySerial API...)

unfortunately I do not really know the differences between TinyG and GrblShield
what do you need to develop the driver?

Need some information:
For file upload, we cannot just read the file and put on serial, the computer is too fast and we have an out of buffers and panic error on Arduino card...
On the TinyG2 I can know how many free buffers is available and drive the upload speed with that... the command is "$qr" for querying the buffers availability... and I make continually while file upload...
and I think I cannot use Dual End Point connection: when you connect your Grbl card how many new port appear? (like /dev/ttyACM0)

it is expected to be able to control the manual machine to place the tool to his "origine" piece?

For now it's expected to make GCode file upload but I just test with TinyG2. I hope many more...
But I tried to make that extra driver development is easy ...

some Arduino hardware to start testing this out

you can test without... just on loop://

Hi,
I think it's grbl that limits data flow.
I read on Github GRBL but not sure.

when you connect your Grbl card how many new port appear? (like /dev/ttyACM0)

I will try to see (I am Linux beginner)

Hi all,

I just released a new version...
Like you can see, now the TinyG2 TaskWatcher Monitor is editable...

TaskWatcher work on all plugin... it's a big deal...


And specially for Xav-83 just make a new plugin for Grbl card...
I hopes it's working...

We can make more on the Grbl plugin, but I need more information...
in fact I need the response of different command:
$$ (view Grbl settings)
$# (view # parameters)
$G (view parser state)
$I (view build info)
$N (view startup blocks)

A copy/paste or screenshot of responses will be nice...
