Hardware Used: NI PCIe 6323
OS: Windows
Application: Homegrown custom Application from Danlaw : MxSuite
Goal : To plot PWM values of a 244Hz PWM signal.
Description: We are trying to plot Duty Cycle of this signal that is 244Hz.
I am looking at Ctr 0 port of DAQ and we have set it to read PWM.
The data looks valid as long as there are pulses coming.
But in a situation where DC does to 100%(Max brightness) and When LED turns Off(0% Duty Cycle)
If PWM is off (flat 0 line), NI DAQ Counter port ctr0 keeps waiting for Next pulse to plot the data instead of showing value as 0% DC.
