Dear all,

I am using the CY8CKIT-043 and I want to convert an analog signal of 100 Hz to a digital one. Indeed, I am using the ADC_Sar_Seq with one channel. When I am getting the results of the ADC conversion, i observed  that the frequency of the ADC's output is always 10 times greater. So, in this case the frequency of the  ADC's output is 1 kHz. I tried some other tests, applying sinusoidal waves of 50 Hz and 60 Hz and I got as output 500 and 600 Hz, respectively. Please help me how to fix that, in order to get the same frequency. 

I submit you some excel files to understand, what I wrote above. Also, I attached  the configuration settings of the ADC 

Thank you in advance.

Please attach your project file for review: File->Create Archive Bundle->Minimal.  In newly created zip archive please delete folder "Generated source" to reduce the size of the uploaded file.

As further suggestion, use insert image icon tool to embed images in the message body, instead of attaching them. This will bring more attention to the post and bypass extra step of downloading images.
