Control of heating/cooling (Peltier) in DC (not PWM)
I am trying to set up a system to control heater / cooler Peltier element like this: +/-5V @ 1. 25A With the help of current continuous (through a PID controller), not a PWM. I am considering using CRIO or PXI platforms. -The CRIO, I found the motion
Writing DAQmx invoke node leads to a runtime error (R6025 - pure virtual function call)
I have a request in which a Subvi DAQmx writing calls calling node (shift of writing and reading NumChans). When I launch LabVIEW and the main VI a first run, everything works fine. When I run a second time, LabVIEW crashes with a runtime to Scriptur

Incorrect voltage to a channel with NI9205
Hello everyone I measure 10 tension of cell with a NI 9205 (differential mode, volt min. = 1, maximum voltage = 3). Everything works fine, until tensions are higher than 2.7 V. channel 17 (cell number 10), the voltage begins to decrease. All the othe
where is the function AI_VRead() defined, which is used in the AIonePoint.c file. ?
Hello I installed the Ni DAQ software for 6024E card. As I walked through the code examples in Visual C, I came across AIonePoint.c file where the AI_VRead() function has been used. But I could not find the function definition. I would like to know w
How to activate digital outport on USB6211?

How to control the sequence of scanning channels in DAQmx
I have an application written for the traditional DAQ C API that I need to convert to use DAQmx drivers. The application uses the SCAN_Setup function to create a canal complex analysis sequence of taste effectively at different rates on each channel
NEITHER USB-6501 not recognized by the system
Hi all I wrote this simple application that writes and reads a SPI frame. My PC have Labview 8.5.1 and DAQmx 8.7.1 (the CD was provided with my unit NI USB-6501). Everything works fine. But now I need to distribute the application, and I need to run
DAQ_Clear for DAQmx
Hello? I'm working on the conversion of DAQ DAQmx. As we know that daq_clear can be worn in DAQmxStopTask/DAQmxClearTask in DAQmx. But the question is, is it possible to stop the task all loaded both in DAQmx? Code of DAQ_Clear. It stops at all the a
USB 6008 - how to display the two position linear pot (mm) and output (volts) in LabVIEW?
I have a USB-6008. I have a linear potentiometer attached to the USB DAQ. Now I can view the output voltage of pot in LabVIEW through the AI0 on USB DAQ channel. However, I would also like to be able to show the position of the stem of the linear pot
DAQ Assistant in labview7.0
Hello Recently, I bought a PCI - MIO - 16 - 4 to fit our labview7.0 DAQ. After installing the driver (from the CD), the card works fine with MAX and labview signalexpress. However, the default program is not at our request. So, I tried to schedule wi
