This folder must contain drivers for various DAQ cards as you see here.

Note that if your kernel version is different from mine,

the path will be lib-modules-your kernel version-kernel-drivers etc.

Wait for a couple of minutes.

Press Ctrl + Z when you get a --> at the end of make.

As we do not use the hard real time component of HART, let us do the following to remove the RTAI related components from HART.

Go to ~/scilab-5.3.x/share/scilab/contrib/hart_0.4.4/etc folder

Modify the HART.start file in this folder( you need to do this in sudo mode, i.e., as a super user).

Comment out the following lines (by adding // to the left of the lines as given below):

// xcosPalAdd(pathmacros+'/palettes/hart_base/hart_base.xpal','Hart');
// xcosPalAdd(pathmacros+'/palettes/rtpreempt/rtpreempt.xpal','Hart');
Instead of the line containing rtprempt.xpal, you will have to comment out:
//xcosPalAdd(pathmacros+'/palettes/RTAI/RTAI.xpal','Hart');
in certain versions of HART

Save and close this file

And go to the contrib folder where hart_0.4.4 is saved.

And then execute the loader.sce file

It is listed under Driver

|-
| style="border-top:none;border-bottom:0.035cm solid #000000;border-left:0.035cm solid #000000;border-right:none;padding-top:0cm;padding-bottom:0cm;padding-left:0.018cm;padding-right:0.018cm;"| Plug in USBDUX FAST.

Type the following in the terminal to ensure that all users have the privilege to read and write into COMEDI devices.

This needs to be done as a super user:

chmod a+rw /dev/comedi*

This needs to be done each time you restart your computer.

You can also ask the OS to do this automatically after each reboot, if you wish to do so.

Plug in USBDUXFAST now.

| style="border-top:none;border-bottom:0.035cm solid #000000;border-left:0.035cm solid #000000;border-right:none;padding-top:0cm;padding-bottom:0cm;padding-left:0.018cm;padding-right:0.018cm;"| Type the follwing in terminal:

dmesg | grep comedi
| style="border-top:none;border-bottom:0.035cm solid #000000;border-left:0.035cm solid #000000;border-right:0.035cm solid #000000;padding-top:0cm;padding-bottom:0cm;padding-left:0.018cm;padding-right:0.018cm;"| Type dmesg pipe grep comedi on the terminal
You can see that USBDUXFAST is recognised as a COMEDI device.

So the COMEDI suite installation is also validated.
