Measuring Digital Pulse Width using TCS3200 and myRIO

[cyongjed]

Hi guys,

Has anyone tried using the colour sensor model TCS3200/ TCS230 linking it with the myRIO to determine the colour?? I have attached my VI here using LV17 Version.

Some queries I have here and hope that someone could assist me with them. I have listed it down here.

• TCS3200 using a TTL Output Logic Level Waveform, what is the best way to measure the pulse width? Output is using the Boolean 0,1 and the results obtained from the existing VI is very erratic for the current VI....
• Is there any internal APIs that I can use to directly measure the frequency of the output TTL waveform?

Thanks in advance.
