 Write a function to generate a 10 us delay using a single load value for the SYSTICK timer. b. Blink the red LED at a 10 us rate when SW1 is held down. c. Blink the green LED at a 100 us rate when SW2 is held down, using 10 calls to the function from part a. d. Blink the blue LED at a 10 ms  rate when both switches are held down, using 1000 calls to the function from part a

    Hay back... perhaps your instructor/professor?  Or - you may help yourself...  (strange idea - that...)

    (have you made any effort to read MCU manual, numerous SW excamples, or search here?)

    Hi Wisam,

         You can start by going through the Tivaware Peripheral Driver's Library User Guide, and review the example code snippets in the doc. Then see, the example programs here "TivaWare_C_Series-1.0\examples\boards\ek-tm4c123gxl" for your review.

     thanks for your help I did well on my frist code but on the second one that I had my code build but that take me to another question how to declare  100ms to blink the LED like every 100ms or 200ms or 300ms ? 

    thank you

    Hi Wisam,

         Based from the systick example code from the example folder. This line below sets the systick period to 1 second. So, dividing the parameter "SysCtlClockGet()" by 10 would set the systick period to 100ms.

    //
    // Set up the period for the SysTick timer. The SysTick timer period will
    // be equal to the system clock, resulting in a period of 1 second.
    //
    SysTickPeriodSet(SysCtlClockGet());
