LAVIEW IV Read multiple channels

This exercise will show how to read multiple analog channels using the NI-DAQ USB-6008. The signs will read will be the various stresses that gives us a voltage divider made ​​of resistors. The visualization of the channels we use LabVIEW 2010.

The DAQ will use allows us to generate or measure both analog and digital signals. In this case we use the analog input channels to view the different voltages of the voltage divider.

We rode the voltage divider plate protoboar and output terminals connect to the DAQ. Feed the circuit with 5v voltage gives the DAQ. Now it design the program in LabVIEW. DAQ functions with which we will read and display.

In this case the reading relates to multiple channels, namely the AI4 AI0 ranging from reading a total of 5 channels. The reading is in Volts for what we are measuring are tensions. Configured so that the reading is done continuously. Finally read channels. Since we want this value is refreshed continuously introduce the statement within a while loop that repeats itself and so refreshed reading. After reading the reading is stored in an array. A control button will stop reading and stop the saw.
