    Joseph,

    The easiest way is to configure a CPU timer to run at the CPU speed and then read its counter from your code. In the header file examples for F28335 you will find the file "DSP2833x_CpuTimers.c" which contains functions to initialize and configure these timers.

    For example, you might choose to set up and start CPU timer 0 in your main file something like this:
    ConfigCpuTimer(&CpuTimer0, 150.0, 10.0e+00);
    StartCpuTimer0();

    You could then read the timer count from your code using:
    t1 = CpuTimer0Regs.TIM.all;

    ...and make a conditional test using t1.

    I hope this helps.

    Regards,

    Richard
