Hello,
I try to read a MEMS microphone with Labview and PCIe-6535 data aquisition card. I have made a program that reads MEMS microphone’s pulse density modulated signal. However, it looks like the microphone doesn’t react to sound. There’s only noise.
The microphone’s data should be readable at either rising or falling clock signal edge. The clock signal is generated by using burst export clock in the program but with this there is no option to choose either falling or rising edge.
Can someone help me with generating the clock signal and reading data from microphone. I’ve attached the microphone’s datasheet and the Labview program.
Regards
Jani
