Wireless embedded systems bridge our physical world with powerful digital control systems and cloud data analytics. Applications range from medical devices such as Bluetooth-enabled blood glucose meters, to payment systems such as Near-Field Communication-based credit cards. In this class, students will learn about how an embedded system works from the ground up. The lectures will focus on the key enabling components of embedded systems, including: Clocks, GPIO, Interrupts, Busses, Amplifiers, Regulators, Power supplies, ADC/DAC, DMA, Storage, and Wireless communication. The goal of the class is to familiarize the students with these components so that they feel comfortable working on a team that is building a device that incorporates a wireless embedded system.

Prerequisites

CSE30 (CSE 120 recommended)

Materials

Reading

We will be supplementing the lectures with material from the following freely available sources:

• Lecture notes: MIT's 6.02 course
• Textbook: "Introduction to Embedded Systems" by Lee & Seshia

Course management

We will manage discussions, grading, and announcements for this course with Piazza.

Grading Criteria and Late Policy

• 20% - Midterm Exam
• 60% - Four assignments
• 20% - Final Exam

The late policy for the course is as follows: you are permitted three total days that you can submit any of the projects late. For example, you can be late one day (24 hours) on three of the projects, or late three days on one project.

Academic Integrity Guidelines

All programming assignments must be completed in your assigned groups. You and/or your partner must write all solutions and code that you submit, excepting any code that was provided to you as part of the assignment. You may discuss the assignments with others, but you may NOT make your code available to others or copy answers or code from another student--this includes GitHub repostiories (or similar) for assignments from this or similar courses in previous terms at any university. You will be issued private GitHub repositories for use in this course; it is your responsibility to make sure your code stays private. Exams will be individual effort and closed book.
