[DASYLab 2022 Measurement Computing Device Drivers Repair, Modify or Uninstall message]

A strange DASYLab MCC-DRV driver situation can occur with multiple versions of DASYLab install on the same computer. Specifically, this applies to DASYLab 2020 and DASYLab 2022 installed on the same computer. If DASYLab 2020 MCC-DRV driver is enabled, trying to enable it for DASYLab 2022 will result in a dialog similar to one below. This is due to confusion on the part of the installation program. The quick solution is to press Cancel and exit the installation program. Then, using the DASYLab Configurator 2020 utility, disable the Measurement Computing driver, then go back to DASYLab 2022 Configurator and enable it

 

If you didn't come across this article and ran one of the options from the dialog below, you may be stuck in a situation where the driver is indicated as enabled but there is no Inputs/Outputs>>MCC-DRV DASYLab menu. The solution for this is to simply run the Configurator utility twice. Once to disable the driver and the second time to enable it. But this only works if DASYLab 2020 driver is disabled.

[DAQami support for Windows 11]

 

The DAQami program does have support for Windows 11 but, there is a catch. Installed by itself does not work and this is because it installs an older copy of InstaCal. Why does that matter? Because InstaCal installs tools that DAQami uses to make your hardware device available to use. With Windows 11 now out, our testing found that InstaCal was not compatible. This was corrected with the release of InstaCal 6.73, however the DAQami installation has yet to be updated to include InstaCal 6.73. Because of this, it is recommended to install both DAQami and the new version of InstaCal. InstaCal doesn't need to be removed ahead of time because the installation program will remove old components and replace them with new. If you already have DAQami installed, all that is need is to update InstaCal. One last note, this only applies to the single DAQami download on the Measurement Computing download page. If instead, the MCC DAQ Software CD is used, its version installs the update version of InstaCal that is included with the CD.

[uldaq, libusb problem on M1 Mac]

If you are trying to install MCC Universal Library for Linux (uldaq) on a M1 Mac, and you see the problem:

During step 3 of the Build instructions, part 2:  $  ./configure && make

During that execution, an error shows up:

‘Library libusb-1.0 was not found on this system’

And you think, "But I know it is installed because I ran the prereq command ‘brew install libusb’!"

At the time of my writing this, the current version of Libusb is 1.0.26.  if there is an update, please substitute the new rev in the following instructions.

Download the source from github.com:

https://github.com/libusb/libusb/releases/tag/v1.0.26

As you know, I’m not a Mac person, so after it downloaded, I unpacked it in the downloads folder, and from the terminal:

Build it in the standard way:

$ tar xvfj libusb-1.0.26.tar.bz2

$ cd libusb-1.0.26

$ ./configure

$ make

$ make check

$ sudo make install

Then you can continue on with uldaq installation at:   $ ./configure && make

To their completion.
