CCS/LAUNCHXL-F28379D: ADC graph

user6412891
Prodigy 170 points

Part Number: LAUNCHXL-F28379D

Tool/software: Code Composer Studio

Hi

I am using the adc_soc_epwm example on the F28379D board, I am new to this topic and to code composer, I have modified the TBPRD to obtain signals of different frequencies, but I do not understand yet how to verify that these input signals are correct. I check the data obtained in AdcaResults expressions and use the graph option but I don't know how it works and how to relate it to the frequency.

I appreciate some information about this.

    The typical approach is to capture an array of samples for graphing in CCS, and for offline analysis.  Once you have your data set, you can reconstruct the sampled signal where the ADC results represent the voltage and the array elements represent different points in time.

    This F2837x Workshop may also be helpful.  A similar exercise is performed in Lab 2 of Section 5.
