Documenting work to get DAQ systems to play nice. Executive summary:
- Do not install NI-VISA drivers if you want MATLAB to work with NI cards.
- Install cards as admin, run MATLAB "as admin" whilst logged in as admin, and daqregister card
- Restart early and often.
- Log in with local admin password
- Start NI-MAX
- Do anything (click on a category, try to expand a category, etc) and note you get - "There was a problem connecting to the database" error 42HG08DD
- Devices and interfaces shows PCI card as "PXI4::2::INSTR" which is a VISA designation
- No way to un and reinstall as DAQmx without removing VISA drivers
- Close NI-MAX
- Control Panel - Uninstall a program
- Select National Instruments Software and click Uninstall/Change; Yes to change
- Select all NI-VISA components at end of list, then Remove Selected - wait as 41 things disappear
- Close the National Instruments Software window
- Close Programs and Features
- Select National Instruments Software and click Uninstall/Change; Yes to change
- Restart computer
- Start NI-MAX
- Log in with local admin password (note - this took several minutes during testing; re-registering hardware? Windows being annoying? Who can say?)
- Start NI-MAX
- Expand "Devices and Interfaces" category (no error this time)
- Now shows as NI PCI-6014 "Dev 1"; click on the name and there are several tabs at the top including "Test Panels"
- Close NI-MAX
- Start MATLAB ***AS ADMINISTRATOR*** (even though you are logged in as administrator...weirdness)
- daq.getDevices() (will take 2 minutes the first time...because of course it does); may show an ni device or not. Regardless,
- daqregister('nidaq'); should get 'mwnidaq.dll' successfully registered
- close MATLAB
- Restart computer
- Start NI-MAX
- Log in as a regular person (grab a snack while Windows is preparing for...something)
- Seriously - this takes about 5 minutes - Windows better be well done by the end of this...
- Start NI-MAX
- Finish snack. This start-up isn't what one would describe as speedy, either...
- Expand "Devices and Interfaces" category
- Still shows as NI PCI-6014 "Dev 1"; click on the name and there are several tabs at the top including "Test Panels"
- Close NI-MAX
- Start MATLAB the normal way
- daq.getDevices()
- (Any snacks left? Perhaps some tea?)
- ((think happy thoughts))
- ni should show up
