Hi everyone.
Iam making a RC-car that have to run by its own. to measure distance I was planning on using ultra sonic sensors.
I just wanted to test the sensor with a quick labview program but I have hit a wall.
Is it possible to send and receive a DIO on the same line on the usb-6009 DAQ?
The test should be run sow I sends out only 1 high node and then waits for the high node to return sow I can calculate the distance as a results of the time delay.
Sow does anybody know if it is possible to send and receive on the same channel?
best Regards Jens

It appears that the output of the USB snap function is always a RGB U32 image, regardless of what the input image is. That is why you are getting the error. The IMAQ Count Objects 2 vi will not accept and RGB image. After the USB Snap, add an IMAQ Cast Image vi to convert it back to a U8 image and then pass it to the IMAQ Count Objects 2 vi. -
