Arduino IO Expansion

Hi, I just updated the code, it now also Supports Matrix Keyboards.
I've managed to add functionality to input actual Keyboard inputs in Linux aswell as defining Functionality Keys to be included as Input Pins in LinuxCNC.
The downside is, that it only works, while LinuxCNC is running.

But - and that is why i added this feature -now the software should be able to fully support Professional HMI Devices like Heidenhein tnc420 for example.
I don't own one myself, but one out of my Community does. Eventually when the Setup is working i will implement the Config in the code for others to copy.

Link to repo:
github.com/AlexmagToast/LinuxCNC_ArduinoConnector

I am very open to feedback if you tested my solution or have questions / suggestions.

Cheers, Alex

Hi,
i just released a video showing the Project i build the Arduino_connector for.
It is a custom control panel for LinuxCNC. It's not the explanation Video i promised earlyer in this thread, but i thought you might still be interested.

Cheers, Alex

In this Thread i was talking with @COFHAL about the use of Encoders and Joysticks, both are supported by the Arduino-connector, but i didn't think somebody would want both in one build. I want to move here, to keep the discussion there to the topic of the matrix keyboard.
Here is the link to the discussion: forum.linuxcnc.org/show-your-stuff/49606...ng-linuxcnc?start=40

@COFHAL, the Encoder and Joystick will generate different counters, with different values. Are you able to write HAL code to switch between them, to use two different Counter Inputs for one Axis?
Also the scale Value will have to be different, depending on the input.

I really don't know how to do it, so what I'm going to do is use the joystick with the analog inputs, but not with the joystick function, but simply as an input to a potentiometer, as I have used in other applications.

Any news on when the update fixes the problem with the Latching Potentiometer function in the latest version?
