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!

da xiong,

Please see this thread on using the graph tool. e2e.ti.com/.../597188
I am also moving this to the CCS forum as well.

Thanks,
Mark

Mark,
thank you!But i just want to use single time graph tool to plot a fft result buffer which is caculated by 28335 to vertify the result， i don't want to use FFT magnitude graph tool, could you please tell me how to configure correct interval to show a buffer of fft in single time graph?the interval means samlple frequency/FFT_SIZE /unit
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
