Realtime OS on Embedded Systems
Contents
Program History
My contribution in Embedded System courses started with CmpE146. This course teaches students on how to write UART, SPI, and I2C Drivers and interface their drivers to peripherals. There are about 8 weekly labs in which students not only write drivers, but also learn the core of Real-time Operating Systems including threading (tasks), and inter-task communication using Queues and Semaphores. FreeRTOS is the operating system used with C/C++ Compiler based on GNU.
When the course was started by Dr. Ozemek @ SJSU (sometime before 2005), not many resources were out there. Still, with helpful guidance from Dr. Ozemek, interesting projects were created. This is when I started to help out in Embedded System Courses, and by collecting and sharing knowledge, we've raised the bar at SJSU!
There have been many great projects at SJSU, but since no one knew about them, the hard work went to a waste for anyone but the creator. But now we've got the infrastructure to share the projects, which turn out as great references for future students. Here is my project that started around 2007, and turned into Bachelor's Senior Design Project:

As of 2013, I have broadened my contribution to other embedded system courses like CmpE240, CmpE243 and CmpE244.

Class Project
Self-driving Car
In this class project, students accomplish a self-drivable RC car with the following learning objectives:
- Learn CAN Bus and how to communicate in an industrial or automotive environment.
- Learn integration and testing across different controllers.
- Learn how to work in teams.
- Learn basics of an RTOS.
Senior Design Projects
Semester Projects
Every semester, students are given about 7-10 weeks to complete their projects. During this short time-span, students form groups, order parts, and begin working on their projects. The work performed during the semester is documented at this Wiki.
Here is the list of Preet's documented projects:
- Preet's Relay Controller Project
- Nordic Low Powered Mesh Network stack
- Senior Design Project (MS-CmpE) Video
