Arduino based USB Pendant for Linuxcnc

Yeah exactly.

From serialcon2.comp

So if you send "X1000.999Y2000.888Z3000.777"

That should populate those axes with those values

Hi @all
can someone tell me what USB Device i put in the serialcon?

After reboot my PC this changes ever +1 usb 7-1: i.e. usb 5-1 / usb 6-1 etc...

I'm using LinuxCNC 2.7.7 on Wheezy.
I want to use only the DRO output no Key Functions or anything.
I changed the Arduino sketch without Keypad. Baudrate i d'ont changed.

Is this Installation from serialcon correct? (i'm not a Linux spec )

[strike]fh@v3:~/linuxcnc/configs/CNCV3$ sudo comp install serialcon2.comp[/strike]
[strike]sudo: comp: command not found[/strike]
fh@v3:~/linuxcnc/configs/CNCV3$ sudo halcompile --install serialcon2.comp

Or must there a lot more?
I put this in my costum_postgui.hal

loadusr -W serialcon
....
net Xposition halui.axis.0.pos-relative serialcon.xposition
net Yposition halui.axis.1.pos-relative serialcon.yposition
net Zposition halui.axis.2.pos-relative serialcon.zposition

No more Files where attached...

I seem to recall that USB devices also show up somewhere else on /dev by serial number.
That might be less mutable.

well, i installed the last Arduino IDE to see what port is used,
it shows /dev/ttyACM0
So i changed this in serialcon to this
#define DEVICE "/dev/ttyACM0"
Should this be ok?
while nothing happens after:

EDIT: i test the Port with the simple Blink-Example, that works...

So i changed this in serialcon to this
#define DEVICE "/dev/ttyACM0"
Should this be ok?

If that is the device port you are using, then it is correct.
/dev/ttyUSB0 is more normal, but depends on the board.

Don't understand what you are trying to say.

The print just shows you have compiled the component and installed it to /usr/bin probably.

However please be aware you have compiled a component called serialcon2, but your hal file is loading a component called
serialcon

loadusr -W serialcon

The name of the file and the component must be the same as each other
github.com/LinuxCNC/linuxcnc/blob/master...ls/halcompile.g#L958
because otherwise halcompile would fail.

So you probably are trying to load a component which does not exist, albeit you haven't actually said what the problem is.
