Issues with USB-CTR04 python example code provided

[YoelGee]

Hello I am currently trying to get frequency reading using one of the counter channels on the CTR04. To help me get started I a using the c_in.py executable to read the pulse count/ frequency. For some reason at 1MHz I am getting the readings bellow where there is a small discrepancy. Is this expected with the device and its python compatibility? When I try to record the frequency on DAQami I get a perfect reading of 1MHz but not on python as seen bellow.

Hello @YoelGee.

The mcculw Python example, c_in.py, reads events from a counter.  From your screen capture, it appears that you have modified the example.  Please attach your example along with the code to review.

Additionally, please reply with a screen capture from your DAQami results as well.

Regards,

Fausto
