About this Course● Preparation for real world work on embedded systems:

– Hands-On experience– Technical manual interpretation– Independence

● Very little hand-holding (e.g., Embedded Control)● Expected to implement labs with little technical guidance

● Website:

Staff● Me: Kyle Wilt● TAs:

– Tahmid Chowdhury (F16?)– Mohammad Haque

● UGSA:

– Ryan Wanner (F20)

● “Helper”:

– Bryce Northrop (F20)


About this Course● 6 Labs and a Final Project

– No HOMEWORK– 3 Quizzes– No EXAMS

● Work in Teams of 2.

– No groups of 3, will accept groups of 1 (with leniency)


Topics by Lab (may be rearranged)1.Basic Terminal (ANSI) and Digital I/O (GPIO)

2.System Interrupts and Timers

3.Serial Communication: UART + SPI

4.Analog/Digital Conversion and Filtering

5.Direct Memory Access (DMA)

6.Options: USB, RTOS, JPEG+DMA2D


Final Project● Entirely up to you/your group but:● Needs to use some functionality from labs● C or C++ based (No Arduino!)

– Open to newer languages, e.g., micropython, rust, etc.● Don’t even need to use class microcontroller

● Talk about it more as it approaches


Course Policies


Policies - Attendance● No strict policy on attendance but…

– To finish course you need to finish labs…

– We’ll notice if one group member does the majority of the work. It’s very obvious.


Policies - Grades● All grades determined through work on labs

– ...Except 15 % to quizzes

● Labs are not weighted equally● Individual grading built into labs as well as overall

“Preparation and Participation”● Curving (up-or-down) of final grades possible

– Grade estimation provided midway through class


Policies – Lab Grading● Task-by-task checkoff and grading (~50 %)● Report (~50 %)

– Only accepted if each required task is completed– -20 points per school day late

● No need to submit report after 5 days late. ● Task completion is still required however.


Policies – Lab Grading● Required Tasks:

– Most tasks are required for you to complete the lab/class

– Can get help on required tasks, though we will limit the amount of answers we give (e.g., won’t do it for you).

● Depth Tasks:

– Not required for completion of lab.

– Apply what you have learned from other tasks WITHOUT HELP.

– Need to complete and checkoff required tasks before “Finish Lab X” date on calendar to attempt the Depth Task

– Worth 10 points on each lab. Partial credit awarded for non-working but good effort.


Policies – Lab Grading● Extra Credit!

– Reports submitted 1 week early will receive 5 point bonus.

● Only required tasks need to be completed– Max of 95 % without Depth task– Max of 105 % with Depth task

● Cannot get credit for Depth task if report is already submitted.


Policies – Lab Grading● Lab outputs uploaded to Gradescope

– Full project code should be submitted as *.zip● Either full project OR ● Just modified file(s) - preferred

– Reports submitted as PDF


Polices - Textbook● Not required but highly recommended:

– Carmine Noviello, 2018, Mastering STM32● Required and provided:

– Any applicable technical document or manual from ST● Many provided on website:

– ${MPS_Website}/resources.html● Also linked to in lab documents.

Microcontrollers, IDEs,Libraries, etc.


Microcontrollers...● Basically a computer on a chip:

– Microprocessor– RAM– Flash– I/O support– More peripherals than you can shake a stick at*

● *At least the one we’ll be using.


Microcontrollers● Desktop/Laptop processor manufacturers:

– x86: Intel + AMD– Others: Apple, IBM, probably a few more...

● Embedded processor manufacturers:

– NXP, Renesas, Microchip (AVR+PIC), Samsung, STMicroelectronics, Texas Instruments, Cypress, Broadcom, Silicon Labs, Analog Devices, Allwinner,SiFive, Nvidia, ...probably a bunch more…

● Ranging from extremely simple to extremely complex:

– ATtiny85 (8-pin, 234p manual) → STMF769NI (216-pin, 1954+p manual)

*See next slide


Integrated Development Envs. (IDE)● IAR and Keil:

– Commercial and expensive!● Generally have excellent support and compiler optimization.

● Eclipse Based (free, generally)

– STM32CubeIDE, TrueStudio, System Workbench (STM32, openstm32.org)– Code Composer Studio, “CCS” (TI)– Simplicity Studio (SiLabs – newer uC only)– MCUXpresso (NXP)

● Netbeans Based

– MPLabX (Microchip)


STM32CubeIDE● Tour…ish

● More Tour on Thursday


Groups● Numbers from a Hat?● Person next to you?● Battle Royale?


Group: Code Sharing● I highly suggest you use git to maintain the code within your group. Git

provides a historical record of your code development.

– https://github.com/– https://about.gitlab.com/– https://bitbucket.org– Tutorial: (This looks like a good one...)– To Install within STM32CubeIDE:

● Help → Eclipse Marketplace → Search for “egit” and install with the default options.
