Create a multitasking program to demonstrate event flags to synchronize task execution. Create four tasks to simulate the operation of stepper motor driver. Use four LEDs blinking to simulate the activation of the four output driver stages. Create another concurrently executing task to display text on GLCD. The stepper motor driver tasks are expected to run sequentially. As the target is KEIL MCB 1800 evaluation board, BSP of LEDs and GLCD shown in previous questions can be used. Use APIs of freeRTOS to manage signals events and explain the APIs
