Writing PWM data to analog using FPGA

Hello,

I am working on a project to read the period of a PWM signal using FPGA. I am transferring that data to the host(RT) to calculate frequency and then convert it into an analog signal to write it on an analog channel in RT.

However, it is not writing anything to the analog channel. Can somebody suggest a proper method to do it, I just want the latest data because the frequency will remain same, so there is no need to buffer? Also, if I can know that what is the possible cause of the error in my VI?

Regards,
