Design of Embedded Systems

All three of our MOOCs are currently active. These are free online classes on embedded systems. There is a physical lab kit you must purchase to do the labs, otherwise the courses are free. For more information on the lab kit and software download for these first two MOOCs. The links to enroll on edX for the first two are:
UT.6.10x Embedded Systems - Shape The World: Microcontroller Input/Output  and
UT.6.20x Embedded Systems - Shape The World: Multi-Threaded Interfacing


The third MOOC covers Real-time Operating Systems with Bluetooth Connectivity. The link to enroll on edX for this third MOOC is: UT.12.01x Real-Time Bluetooth Networks - Shape The World  For more information on the lab kit and software download


Exciting News: I got a wifi client system working with the low-cost ESP8266 wifi module for both TM4C123 and MSP432 microcontrollers. The project connects to an access point and fetches weather data from View the ESP8266.c file. Download project. Instructions to create your own data logging server using Google App Engine.

Embedded System Courses I teach at the University of Texas  Keil uVision installation and configuration     Data sheets  How to install EE319K/EE445L/EE345M software on a Macintosh Installing LaunchPad drivers: 1) Download and unzip windows drivers for the TM4C123 from, alternative download 2) Plug TM4C123 LaunchPad board into PC (debug port) and turn on power; 3) Open device manager in Windows, and for each TI driver (twice), a) right click the missing driver (yellow triangle), b) update driver, browse to spot where you just downloaded and install, Windows 7 details. Windows 8 and 10 are similar to Windows 7. Windows 8 and 10 no longer need driver signature turned off.

EE319K Introduction to Embedded Systems   Syllabus Fall 2018    Email all professors and TAs    Fall 2012 Design Competition   Spring 2013 Design Competition Fall 2014 Design Competition  
Undergraduate class: EE319K students discover how the computer interacts with its environment. Students have hands-on experiences of how an embedded system could be used to solve EE problems. The analog to digital converter (ADC) and digital to analog converter (DAC) are the chosen mechanism to bridge the CE and EE worlds. EE concepts include Ohms Law, LED voltage/current, resistance measurement, and stepper motor control. CE concepts include I/O device drivers, debugging, stacks, FIFO queues, local variables and interrupts. The hardware construction is performed on a breadboard and debugged using a multimeter. Software is developed in assembly and in C for a ARM Cortex-M TM4C123 microcontroller. Prerequisites: EE306 or BME303 with a grade of at least C-.

EE445L Embedded Systems Design Lab   Syllabus Fall 2018    Old Exams  I am teaching EE445L this Fall 2018, and again Fall 2019. Professor McDermott will teach EE445L in Spring 2019.
Undergraduate lab class: Review of the Arm Cortex M instruction set, TM4C123 I/O, timing hardware and signals, memory organization, data structures in C, programming style, documentation, real time debugging, buffered I/O using interrupts, programmed logic control, table and linked list interpreters, serial and parallel I/O, keyboards, LED's and LCD's, PCB layout, Data Acquisition, Motor control, ZigBee Wi-Fi wireless, and systems.
