CCS/TMS320F28335: Get in memory a Analog Signal Input through the ADC and plot it

Jose Morale
Prodigy 10 points

Part Number: TMS320F28335

Tool/software: Code Composer Studio

I have a +-10V transformer going through a Signal Conditioning board to have a 0-3V output into the DSP28335, and I want this external output to go in ADC and save it on memory to graph it later. 

I have followed Module_08 - F2833x Analogue Digital Converter, and at last I guess pointing the graph to this variable should do

Voltage_VR1 = AdcMirror.ADCRESULT0;

But I am too confused now. Should I make Voltage_VR1 an array? Like Voltage_VR1 [50] so it can be ploted?

I am really confused on how I get an external input to memory, I think this is the main problem. It should first go thro all the ADC and this result is the one that I want in memory right? 

Thanks and excuse my ignorance 

PS. Im using CCS4

    Hi Jose,

    The graph that you mention above is the CCS Graph tool or some external tool? If CCS Graph tool, you can simply plot the variable itself (Voltage_VR1) and not the array. You can also convert the digital value to analog value and then plot it. In your case the later would make more sense.
