You can also change the sampling frequency. Documentation is installed and should be available from the following location file:///Applications/National%20Instruments/NI-DAQmx%20Base/documentation/docsource/daqmxbasecfuncindex.htm Follow the instructions above to compile mglDigIO and related functions. portNum defaults to 2, to write from Dev1/port2. portNum can also be set to: -1 closes any open port -2 displays which port (if any) is open. check my blog
The time in seconds that you want the digital port to be set. Get counter value: $ ./inp -s 1 -c 0 Set counter value to 255: $ ./outp -s 1 -c 0 255 There isn't however a suitable demo application for arming the This tool will download and update the correct National Instruments NI USB-6501 driver versions automatically, protecting you against installing the wrong NI USB-6501 drivers. Subsequent calls will be faster.

How to set up a National Instruments card You can use a National Instruments card for digital I/O with mgl by doing the following: Download NI-DAQmx Base. For digital input, we use Pin 5 (black, ground) and Pin 1 (red). It always returns 0. Ni Usb-6501 C# Example Note that this does not shutdown the digIO thread.
You must start one event at least 25 ms after the last event even if they are on different output channels. If you plan on starting and stopping digIO collection, you should use init and quit rather than shutdown Analog output using mglDigIO mglDigIO supports limited analog output functionality. About The Author: Jay Geater is the President and CEO of Solvusoft Corporation, a global software company focused on providing innovative utility software. Support Library Explore a wide range of support content, including examples and troubleshooting information.
Also, if you want to switch between reading and writing on a single port, you will need to manually close the port in between read/write calls by setting portNum = -1 Ni Usb 6509 The function mglDigIO when called to get digin events or set digout events connects through the socket and communicates with mglStandaloneDigIO. National Instruments NI USB-6501 drivers are tiny programs that enable your Digital I/O hardware to communicate with your operating system software. Look for the marks on the product label for verification of certification.
However, we found that the driver needs to have c# support through the Mono Framework and were not able to find a way to make this compatible with Matlab through a Note that if you are trying to read events up to about 250Hz (e.g. Usb-6501 Oem For example if you want to read channel 5 (-s means subdevice): $ ./inp -s 0 -c 5 If you want to see the inputs change value, you can simply connect Ni Usb 6501 Example For further details, have a look at doc/documentation.html. © 2017 GitHub, Inc.
Log in or Create a profile Support Home Public Discussions Knowledge Base Go to MWorks → MWorks Support Search Home → Knowledge Base → I/O Devices → Setup for using NI-DAQ click site Put arm_counter.c in the demo directory and compile it: $ gcc arm_counter.c common.c -L/usr/local/lib -lcomedi -lm -o arm_counter You can now reset and start the counter with this command: $ ./arm_counter mglDigIO('ao',-4,0,500,2,3); mglDigIO('ao',-7,1,250,5,3); However, you can produce a sine wave of the same frequency on both output channels at the same time for the same duration with different amplitudes. To use this function, you will need to compile it using mglMake('digin'); Here are thte commands it accepts: command purpose 1:'init' Init the digIO thread. Ni Usb-6501 Programming
You can call init with different port numbers to reset what ports you want to listen/write to/from without calling quit inbetween. 2:'digin' Returns all changes on the input digital port 3:'digout' The reason for this is because of the NI-DAQmx Base API.
