    Hello Augusto,

    Here is a link to TI's controlSUITE, which contains ADC sample code for the F28335 called "Example_2833xAdcSoc". This should be a good start for your solution. To run in continuous mode you will need to insert the following into your sequence for ADC setup:

    "AdcRegs.ADCTRL1.bit.CONT_RUN = 1;"

    Once you have the ADC setup correctly, you should be able to run a loop and store your results into an array.

    Check out http://processors.wiki.ti.com/index.php/C2000_Archived_Workshops and look for the archived workshop on the F28335. (I would pull down the latest - which has "Delfino" in the title.) Chapter 6 is on the ADC, and it contains a lab that uses the ADC interrupt. Chapter 7 is on the control peripherals, and has a lab that generates a PWM which is then routed to the ADC and viewable on the graphing tool of Code Composer Studio.

    Hopefully, that helps.
