Introduction Using TI RTOS System to implement the Color Run Game. Objectives Learn to use TI RTOS Learn to design a RTOS on Tiva C LaunchPad Learn to interface Tiva C LaunchPad with peripherals Description Project requirement: Choose a RTOS design that has at least the following threads 2 HWi (posted as SWi) 3 Tasks Idle Identify the threads in your system design Develop the SYS/BIO to run the threads Demonstrate system operation on Tiva C LaunchPad with the peripherals.

Details We decide to design a touch game named .

Rules of
•There are 6 different colors on the screen, and one word of color •Tap the right color according to the word •The color of the word is used to confuse you •You have 2 seconds to get the right answer •There are 3 conditions: If you tap right, you get 1 point and the screen refreshes If you tap wrong, you lose 1 point and the screen refreshes If you don’t tap, the screen refreshes after 2 seconds and you lose 2 points •You have 5 points at first, the game ends when your points are below 0. And the screen shows your highest score you ever got •Enjoy the game!!!

(2)Swi • TouchScreenSwi Posed by Hwi ti_sysbios_family_arm_m3_Hwi0 • Timer2Swi Posed by Hwi HWI_TIMER2

(3)Task • TimerTask Semaphore: AnoSem, posed by TimerTaskFxn() To disorder the 6 colors ramdonly and refresh the screen if the game is not yet end • grlibTask1 Semaphore: QueSem, posed by TouchTestCallback() To draw the screen: 6 colors and 1 color word • Timer2task Semaphore: Timer2Sem, posed by Time2SwiFunc() To detect if player tap the right color and calculate the score, if score decreases to 0, stop the timer, if not, pose to active TimerTask
