Embedded and Real Time System Programming

main_program.c gives an overview of what the program do. dcMotor.c gives an overview of how to use bitwise operations to control the motor in TI-RSLK Kit Set. To lauch the program on Code Composer Studio, please download the zip file.

Polling Vs Interrupt

The robot is programmed to have two mode of operation, Autonomous mode and Free-motion mode using both Polling and Interrupt techniques. In Autonomous mode, the robot operates using predefined route and immediately stop when any of bump switches are touched. In Free-motion mode, the robot freely move forward but will change direction of movement according to the interrupted bump switches.

Real Time Operating System with Round Robin Algorithm

By implementing in Real Time Operating System, music would be played simultaneously when these tasks are performed.

Key Concepts:

• Difference between Interrupt latency and Polling latency
• Real-time operating system and Scheduling mechanism in RTOS
• Use of semaphore
