Hi all, working on my first reconfigurable IO project using a PXI 7811R with LabVIEW RT. I am building a quadrature encoder counter using a couple of the NI examples, and was wondering if there were any caveats to changing it to use an I-64 as the counter output? The NI example uses a 32 bit integer for the count. In my version, I changed it to an I64 count output and added a speed (counting ticks between pulses) output as well. It seems to work fine, but would appreciate any cautions that experienced FPGA users might have. Neville. PS. Cross posted to info-LabVIEW as well.

Hello, I'll explain the application that I have to make. I have a laser sensor (Scan Control) which rotates with an electric motor, it will measure a hole. For that, he turns and must to collect data for each grade of rotation. 180 / half turn -> 180 points / half turn. I have already a Labview program that translates the data sensor in mm. Now I have to make a program to to synchronize the data acquisition. I thought about two solutions: -Drive will sent the triggeur (I do not know if it can be done) -Analog encoder with a rising edge of the sine or cosine signal. The encoder has 32,000 points per revolution (resolution) so it should acquire at each 32000/180 = 180 periods of the encoder signal. How can I do this on Labview? I hope I have expressed well, Thank you in advance to all.
