CCS/EK-TM4C1294XL: How can I configurate Clock_tickPeriod in Code Composer Studio?

Tool/software: Code Composer Studio

To whom it may concern,

I want to use EK_TM4C1294XL for controlling a high frequency power inverter. I wanted to run some example codes that I have downloaded from the original website of TI. I need some assistance to solve some problems related to Code Composer Studio.

I created an Empty Project in TI-RTOS Example. After that, I have composed a program that simulates a PWM Module. However, I would like to change the system clock setting (Clock_tickPeriod) due to the working principles of the Task_sleep() function that changes the current task's mode from Mode_RUNNING to Mode_BLOCKED, and delays its execution for nticks increments of the system clock, where the actual time delayed can be up to 1 system clock tick less than nticks due to granularity in system timekeeping and the time elapsed per tick is determined by Clock_tickPeriod. So, how can I declare a value for Clock_tickPeriod?

Secondly, I have created two pulse generators that do not work at the same time but 1280 ns apart from each other. How can I synchronize these two pulse generators to get output at the same time?

Moreover, I have created a while-loop , which can be seen down below, that includes two GPIO_toggle () functions. Is it possible to combine these functions into one?

 while (1) {

GPIO_toggle(Board_LED0);

Task_sleep((float)arg0);

GPIO_toggle(Board_LED1);

}

I kindly request your imminent assistance to solve this issue, which I'm on a deadline for.
