Part Number: TMS320F28335

Tool/software: Code Composer Studio

hello,i want to use ccs6 single time graph tool to plot a fft result buffer, the frequency resolution is 195hz, but how to configure the x axis to meet 195hz/unit and what's the meaning of the sample_rate? i do this task online and require high real-time property.

thank you!

    Hello,
    Please refer to the CCS Help ('Help -> Contents') for more documentation on the graphs and how to use them. Search for "Graph" and you should see several useful results. The "Graph Properties" topic is likely of most interest as it describes all the configurable properties to set up your graph.

    Thanks
