Kernel module for the National Instruments DAQCard-4050 PCMCIA Digital Multimeter card.
The code is written according to the MHDDK for Windows CE example provided by the NI here: https://lumen.ni.com/nicif/us/evalmhddk/content.xhtml
I have tested all of the measurement modes, and works fine.
The code can compiled under 2.6.38, and probably on the most modern kernels (2.6=<). (I have verified only under it.)
The module requires no NI software to be installed.
