I tarballed /etc/ and /usr/local/bin/ from the old PC, and stuck the files in my home directory where they would be recoverable if the old PC died. This is advisable if you're updating the OS on the same PC, in case you accidentally wipe the old partition or something goes wrong during the installation (eg in resizing partitions). /etc/ for configuration files (including our own, for the stages, the SLM etc) and /usr/local/bin/ just as a reminder of the extra stuff (mainly our own) that we installed.

=== comedi kernel drivers the NEW way (matt 2012)===
 
−
 
−
The comedi drivers are now included in the kernel, but for now they are in the "staging" area.  On SUSE these drivers are not built by default and the way to get them is to install the kernel sources and remake the kernel with these staging drivers installed.
 
−
 
−
Assuming you have the kernel drivers and all relevant tools installed:
 
−
 
−
* cd /usr/src/linux
 
−
* su
 
−
* make cloneconfig
 
−
* make menuconfig or make xconfig
 
−
* select "Device drivers":"Staging drivers":"Data acquisition support (comedi)"
 
−
 
−
There should now be an "M" in the < > next to this. There should also now be loads of comedi related options. Select the relevant ones- you may have to descend the options tree to find yours.
 
−
 
−
(note: generic instructions say "change the kernel name" so as to distinguish it from your current kernel ("general setup":"Local version"). since all you are doing is adding some comedi modules, the kernel rebuild is fairly safe. Skipping this step saves a lot of hassle when it comes to video drivers (ie nvidia))
 
−
 
−
* make (first time this can take a long time, go for lunch!, most of the time is spent compiling things you probably do not want - SUSE includes a lot of obscure modules by default)
 
−
* make modules_install
 
−
* make install
 
−
 
−
In theory on reboot the drivers should just be loaded as required
 
−
 
−
If you want to build the drivers from the comedi source you can follow the old way instructions below.
 
−
 
−
=== comedi kernel driver compilation the OLD way ===
 
−
 
−
The "current release" version of the comedi is 0.7.76, however this will not compile on modern kernels (it's more than 7 years old). The current comedi policy seems to be one of continuous code development, they seem to have given up on producing "releases." We need to create a directory on the local disk (there is a lot to compile) and download a "git snapshot".
 
−
 
−
*cd /usr/local/src/
 
−
*sudo mkdir comedi
 
−
*sudo chown <your_username>: comedi
 
−
*cd comedi
 
−
 
−
The following two lines are from the comedi download page (and it's worth checking they are still correct, as they occasionally change which version control software they use): http://www.comedi.org/download.html
 
−
*git clone git://comedi.org/git/comedi/comedi.git
 
−
*cd comedi
 
−
*./autogen.sh
 
−
The "./configure" script needs some extra arguments to work (ref Roger). "./configure -h" to see all options. These might change in the future.
 
−
 
−
For 32- or 64-bit (tested by Steve):
 
−
*./configure --with-linuxsrcdir=/usr/src/linux

*make
 
−
*sudo make install

==== Specific instructions for the Amplicon PCI230 ====
 
−
(See also Roger's Troubleshooting Tips below for other cards, and for getting comedi to cope with kernel updates)
 
−
 
−
===== Older versions of comedi =====
 
−
For old versions of comedi, you need to run comedi_config after you install your card's driver. For new versions of comedi, this is done automatically. If you've got more than one card in your PC, then I guess google it.
 
−
 
−
*sudo echo 'install amplc_pci230 PATH=/sbin:/usr/sbin:/usr/local/sbin:$PATH; comedi_config /dev/comedi0 amplc_pci230' >> /etc/modprobe.d/99-local.conf
 
−
**Means that when you use ''modprobe'' to load the amplc_pci230 module, it automatically runs ''comedi_config'' too.
 
−
**Unfortunately, ''udev'' ignores this, so we have to...
 
−
*sudo echo '/sbin/modprobe amplc_pci230' >> /etc/init.d/boot.local
 
−
*sudo echo '/usr/local/sbin/comedi_config /dev/comedi0 amplc_pci230' >> /etc/init.d/boot.local
 
−
**Makes the PCI230 modules get loaded automatically at boot time
 
−
 
−
===== Newer versions of comedi =====
 
−
As you no longer have to run comedi_config, then you don't need to tell modprobe about comedi_config, and all you need is the following line that will install your driver at boot time:
 
−
*sudo echo '/sbin/modprobe amplc_pci230' >> /etc/init.d/boot.local
 
−
 
−
==== Troubleshooting tips ====
 
−
 
−
Installing comedi onto different machines may require a slight modification to the approach above.
 
−
 
−
*Change the name of driver (amplc_pci230 above) depending on the DAQ card used (e.g. most PCI National instruments DAQ cards use ni_pcimio). A complete list can be viewed on [http://www.comedi.org/hardware.html comedi's hardware list].
 
−
*Some drivers may not compile using make. If this happens, put #if 0 and #endif at the top and bottom of the driver's code respectively. The drivers are located in ./comedi/drivers/, adv_pci1710.c and adv_pci_dio.c have been known to cause problems.
 
−
*Once installed, if the modules do not load into the kernal using modprobe (e.g. if comedi_test returns cannot find comedi0 or drivers), insmod may be required. The following needs to be placed in and at the end of /etc/init.d/boot.local (these are for National Instruments DAQ, change drivers as required)
 
−
**/sbin/insmod /lib/modules/comedi/comedi.ko
 
−
**/sbin/insmod /lib/modules/comedi/drivers/8255.ko
 
−
**/sbin/insmod /lib/modules/comedi/drivers/ni_pcimio.ko
 
−
**/usr/local/sbin/comedi_config /dev/comedi0 ni_pcimio (if this is not already there)
 
−
 
−
==== Dealing with kernel updates ====
 
−
 
−
Updates to the kernel mean that the comedi drivers need to be reinstalled. As the kernel updates are usually fairly minor, the comedi drivers usually don't need recompiling. It's annoying having to deal with this, so this solution helps to remove some of that annoyance. When you've installed comedi run the following as root:
 
−
 
−
cp -r /lib/modules/$(uname -r)/comedi /lib/modules/
 
−
 
−
This will copy your current comedi installation to /lib/modules/comedi.
 
−
 
−
Now add the following to /etc/init.d/boot.local (*before* any of the commands to load the comedi modules):
 
−
 
−
KERNEL=$(uname -r)
 
−
 
−
if [ ! -d /lib/modules/${KERNEL}/comedi/ ]; then
 
−
        cp -r /lib/modules/comedi /lib/modules/${KERNEL}/
 
−
        depmod -a
 
−
fi
 
−
 
−
This will check for the presence of the comedi directory in the modules directory for the current kernel and copy it over if it doesn't exist. ''depmod -a'' updates the module dependencies.
 
−
 
−
It is important that if you install a newer version of comedi that you remove /lib/modules/comedi and replace it with your updated version. Also note that some kernel updates may be incompatible with your compiled comedi drivers and so you'll have to recompile and reinstall using the instructions above.
 
−
 
−
=== comedilib ===
 
−
 
−
comedilib should now be installed automatically through Roger's openSUSE repository. Updates will also become available through the normal update procedure. If this doesn't work for any reason, see Roger or use the old method:
 
−
 
−
cd /home/scan/source/hardware/comedi/comedilib-0.8.1/
 
−
make distclean; ./configure; make; sudo make install
 
−
Installs:
 
−
 
−
* libcomedi
 
−
* comedi_test
 
−
* /usr/local/sbin/comedi_config
 
−
 
−
=== Comedi Settings for the NI PCI-6251 ===
 
−
 
−
If you want to use the PFI port as a digital output, you must do some extra configuration. This is possible using the demo tools in comedilib (which could also be copied across to your own code of course). So, to change channel 14 of subdevice 7 (ie. pin 1 on the connector) to be a digital output do the following in the comedilib/demo directory:
 
−
 
−
* ./choose_routing -s7 -c14 16  # NI_PFI_OUTPUT_DO == 16
 
−
* ./dio -s7 -c14 1        # now its an output
 
−
* ./outp -s7 -c14 1  # test the output (or 0)
 
−
 
−
All these can be set up at boot. Putting /usr/local/bin/choose_rooting -s7 -c** 16 for all/any channels in /etc/rc.d/boot.local and copying (as root) choose_rooting from the demo folder in (compiled?) comedilib to /usr/local/bin/.

=== Comedi on openSUSE 11.4, Kernel 2.6.37.6-0.5-desktop  ===
 
−
I did a clean install of openSUSE 11.4 64bit on Settee. I had a few problems, so I thought I'd write down how I finally managed to get it working. This was June 2011, on Settee (Samuel).
 
−
 
−
After running ~share/suse_hacks/<suse version>/std_suse_hacks_<location>, make sure to run the install_eee_packages too. This will install comedilib automatically for you, amongst other things.
 
−
 
−
I tried to use the kernel tree to install comedi. From /usr/src/linux/ type: '''sudo make menuconfig''', and choose to install modules for comedi and the relevant drivers. Comedi may be found in the tree under Device Drivers >> Staging Drivers >> Data acquisition support (comedi). Use / for search if so desired. Use '''sudo make modules'''; '''sudo make install''' to install. Unfortunately, this method didn't work for me, and the modules for other devices like network cards got overwritten, so I had to rescue the system.
 
−
 
−
I thus downloaded the latest snapshot from the [http://www.comedi.org/downloads.html comedi download] page, untarred it to /usr/local/src/comedi, and used '''./autogen.sh''' then '''./configure --with-linuxdir=/usr/src/linux'''. It correctly detected the 64bit arch. Run '''make''' then '''sudo make install''' to install. Use the directions above to add the relevant lines to /etc/init.d/boot.local. Since I use the NI PCI6251, the lines in my boot.local file are :
 
−
 
−
KERNEL=$(uname -r)
 
−
if [ ! -d /lib/modules/${KERNEL}/comedi/ ]; then
 
−
  cp -r /lib/modules/comedi /lib/modules/${KERNEL}/
 
−
  depmod -a
 
−
fi
 
−
 
−
/usr/local/sbin/comedi_config /dev/comedi0 ni_pcimio
 
−
choose_routing -s7 -c0 16 # NI_PFI_OUTPUT_DO == 16
 
−
choose_routing -s7 -c1 16 # NI_PFI_OUTPUT_DO == 16
 
−
etc etc
 
−
choose_routing -s7 -c14 16 # NI_PFI_OUTPUT_DO == 16
 
−
choose_routing -s7 -c15 16 # NI_PFI_OUTPUT_DO == 16
 
−
 
−
choose_routing is available from comedilib/demo/.libs/. Copy using sudo to the /usr/local/bin/
 
−
 
−
Hopefully that helps.

I had to make a once-only change to blanket's c_scan Makefile, due to going from a 2.4 kernel to a 2.6 kernel (and subsequent change of BNS device driver).

The Andor camera setup we use uses a client / server model to overcome some of the shortcomings of

the Andor driver / libraries.  All the code can be found in  /home/scan/source/hardware/andor_camera/camera.

You need to make the camera_driver and the camera_utils all application code should use and compile

in the camera_client code. Before you use anything the server needs to be running (camera_server).

Placing the following line in boot.local AFTER the Andor code will ensure it runs at boot time:

echo Installing the camera_server

su matt -c /usr/local/bin/camera_server &

Remember the meminfo thing! reserve at least 4Mb of RAM for the driver by adding this to the boot options in the grub boot

script (menu.1st) mem=1000M where 1000 is the size of the RAM in Mb - 4 (maybe 5?) as in:

The current driver 2.82-30003 on kernel 2.6.27.xx appears to be working, however, Andor seem to be ironing out a few bugs still so this could be volatile - if you have a working system I suggest leaving it alone.

2.78 works on pre 2.6.25 (or thereabouts) but not after because it causes hard kernel locks, it also requires a little hacking

Latest revision as of 15:31, 28 February 2023

Extra stuff for all the experimental hardware that might need setting up. The information contained here will also be useful if you want to install any of these bits of hardware on any other Linux PC.

2023 Update

Experimental PC Kubuntu 22.04 supersedes most of this page.

2022 Update

Much of the information in the Experimental PC old page is now out-dated and/or refers to hardware that is no longer in use. This new page attempts to build a modern version, please contribute by adding instructions for software they use regularly.

Back to Linux How-tos


Pre-install

Scenario 1: inherited PC with working hardware, updating Linux

  1. Make a list of all the hardware you have (or likely to have) attached to the PC
  2. From this list, work out which programs/utilities you use
    • Most of these will already be installed in /usr/local/bin/
  3. Work out how to recompile (and re-install) all these programs
    • Most will have their source code in /home/scan/source/hardware/
  4. Save all the configuration files you think you might need
    • Most of these will be in /etc/


Scenario 2: Adding new hardware to an already up-to-date PC

  1. Use this wiki, find the instructions for the relevant hardware
  2. Any extra configuration files you need (e.g. /etc/stages/IW_stage_origin) - copy off a PC that already has this hardware installed (or you may find a copy in /home/share/backup_system_files/<name of PC> )

PI pci stages*

Experimental PC Old instructions on this cover up to driver_2.6. Below are updated instructions for driver_3.xx_v1.0, but are sios specific! sios install may need to be ported from L4, or sios may need to painfully upgrade to latest os/kernel.

  • cd /home/scan/source/dev/pi_pci/driver_3.xx_v1.0/library/
  • make clean; make; sudo make install;
  • // for new PC may need to double check that g++ is installed, and possibly libncurses5-dev
  • cd /home/scan/source/hardware/pi_pci_stage/
  • // for kernel versions 5.4 and older certain headers don't have consistent filepaths wrt /usr/src/*headers* and /usr/include/linux/. so below is mainly specific to outdated kernels in sios at the moment.
  • // cp /usr/local/include/pi_stage.h from ejectorseat to your local experimental pc (last stable version for sios on ejectorseat)
  • make clean; make; sudo make install;
  • cd /home/scan/source/dev/pi_pci/driver_3.xx_v1.0/driver/
  • // permissions for this directory are wild, root and scan users don't seem to be able to write/access certain files during "make" so temporary work around right now is to cp -r the entire /driver directory onto the local disk (e.g. in /tmp/something) where the local user for sure has full permissions on every file and sub-directory
  • make
  • // if there are errors about /etc/pi_stage/position not existing cp or mv position_um to it. if there are errors complaining about things at the kernel level, then you might need to install source files: sudo apt-get install linux-source
  • sudo ./install_pi_stage


PI USB stage driver

I think the format of udev rules has changed since the scripts were first written and the SYSFS should be replaced with ATTRS. This should fix the problem of the device not being recognised automatically when plugged in.

  • cd /home/scan/source/hardware/pi_usb_stage/utils/cmd_line_utils/
  • make clean; make all; sudo make install;
  • sudo ./actually_install_pi_usb
  • check if /etc/udev/rules.d/98-pi-usb.rules exists and change SYSFS to ATTRS (the remove rules should still be okay).
  • cd /home/scan/source/hardware/pi_usb_stage/utils/manual_usb_stage/
  • make clean; make all; sudo make install;
  • look at /etc/pi_stage/usb_installed_stages, change stage_model_here to whatever model file you need to use... (axis 0 m-062.pd)

Newport mirrors

Control of the capacitive feedback newport CONEX mirror. Separate scripts for Newport Agilis exisit.

  • cd /home/scan/source/hardware/newport_CONEX
  • sudo make; sudo make install;
  • Installs:
    • newport_control

and copies the appropriate udev rule to the local machine.


c-scan

  • cd /home/scan/source/hardware/scanner/
  • edit or create the Makefile for your machine - i.e. Makefile.swing you need to comment in the modules you want to install here
  • make clean; make; sudo make install
  • sudo cp ~sds/bin/cscan /usr/local/bin/
  • Installs:
    • c_scan
    • c_scan man pages
    • cscan: this performs a "touch" on the con-file that you're running with c_scan, so you can see the time at which you started the scan, and - by the time stamp on the data file - the time at which you finished the scan.


d-scan

Modern version of c-scan with greater flexibility etc.

  • cd /home/scan/source/d_scan/d_scan
  • edit or create the Makefile for your machine - i.e. Makefile.swing you need to comment in the modules you want to install here
  • make clean; make; sudo make install
  • Find errors and debug
  • Fair chance you'll run into problems with the OpenCV version, you'll need to get an older version from the git repository ~good luck~.
