Guides on Compilation / Execution Notes:

Hardware Used: Freedom Board FRDM KL25Z IDE Used: MCU Xpresso (https://mcuxpresso.nxp.com/en/welcome)

Build Using Macros:

1. To run the program in Debug Mode set the log_level_a in logger.c to 1.

2. To run the program in Normal Mode set the log_level_a in logger.c to

3. Program 1 and 2 are executed using #ifdef macros.

   #if PGM_1 // runs program 1
   
   #if PGM_2 // runs program 2

Observations:

1. We faced issues using semaphores to control access to the shared LED with the application hitting a hard fault. Used flags to deal with this.

2. Priority setting for tasks only lead to the highest priority task being executed, and hence had to change a few underlying modules.

3. TaskDelayUntil gave various hardfault errors woth semaphores, we weren't able to fix it, but will work on it in the future.
