Modern Embedded Systems Programming Course

Welcome to the "Modern Embedded Systems Programming" video course.

In this course, you'll learn how to program embedded microcontrollers the modern way, from the basics all the way to the contemporary modern embedded programming practice.

The unique approach of this course is to step down to the machine level frequently and show you exactly what happens inside your embedded microcontroller. This deeper understanding will allow you to apply the concepts more efficiently and with greater confidence.

If you are looking for a practical, hands-on, well-structured, and in-depth course explaining the essential concepts in embedded programming, this free course is right for you.

Relevance

The course started already in 2013, so a legitimate quesion is: "Is it still relevant?" The answer is YES, perhaps even more so than in 2013, for two main reasons:

Fundamental Concepts

This course focuses on the essential and fundamental concepts in embedded programming, which never go out of style. All presetned concepts are covered in-depth, and include:

ARM Cortex-M Architecture

This course focuses on the prevalent ARM Cortex-M architecture, which over the past decade became unquesionably dominat in the embedded MCU market. Familiarity with ARM Cortex-M is the most sought after skill that employers are looking for.


ARM processors, including the Cortex-M family

Instructor

The course is designed and taught by Miro Samek -- an embedded software expert with over 30 years of experience. Miro enjoys teaching, and this video course, his books, articles, and conference talks helped many developers improve their skills, pass tough job interviews, and get hired for embedded programming positions.

Prerequisites

The course starts with the basics, but this part is short and focused on the embedded aspects of programming in C. Therefore, you might need to supplement this course with a general study of the C programming language. You might also want to learn a bit about how a CPU works.

Also, this course is hands-on, meaning that to get the most out of this course you can and should follow along and run the discussed projects on your PC. To do this, you will need some hardware (an embedded board) and software (an embedded development toolset).

NOTE
Several early lessons use a simulator and therefore you don't need the embedded board right away. More advanced lessons, where you interact with the MCU peripherals (such as GPIO, etc.) require an embedded board.

Hardware

The main embedded board used throughout the course is the TivaC LaunchPad board (a.k.a., EK-TM4C123GXL) based on the ARM Cortex-M4F microcontroller from Texas Instruments. The board is inexpensive and is still available for purchase from multiple electronic distributors. It is self-contained and provides a built-in hardware debugger/programmer (Stellaris ICDI) that enables single-step debugging and inspecting the internal state.


TivaC LaunchPad (EK-TM4C123GXL)

The course downloads now also contain project versions for the STM32 NUCLEO-C031C6, based on the ARM Cortex-M0+ MCU. The board is also inexpensive, self-contained, and includes an even more versatile built-in hardware debugger (ST-Link) that enables single-step debugging and inspecting the internal state.

NOTE
Course projects for other inexpensive embedded boards will be added in the future.

Software

In order to build and run the code presented in this course you will need one of the following embedded toolsets:

IAR EWARM

The course started with the IAR Embedded Workbench for ARM (EWARM), which is used in lessons 1-19. IAR EWARM is a professional toolset with a good compiler and stable debugger.


IAR EWARM with one of the projecs

NOTE
IAR EWARM used to be available under a free, size-limited KickStart licensing, but recently, IAR Systems stopped offering free licenses. The only free option left is a 2-week evaluation license. Projects for IAR EWARM have been updated to the newer versions of the toolset and are provided for lessons 1-19.

KEIL MDK

KEIL MDK (Microcontroller Development Kit) is another professional development toolset used in this video course. In contrast to IAR EWAR, KEIL MDK is offered under increasingly permissive licensing, including free Keil MDK v6 Community Edition.


KEIL uVision IDE with one of the projecs

NOTE
KEIL MDK projects are now available for all lessons of this course. This includes lessons 1-21, which originally were presented for IAR EWARM or TI CCS.

TI CCS

Due to popular demand, two lessons of the course (19 and 20) demonstrate the Code Composer Studio (CCS) IDE from Texas Instruments. The only valuable aspect here is the use of the open source GNU-ARM compiler and linker.

NOTE
Code Composer Studio (CCS) 11 uses the TI compiler by default and no longer comes with the GNU-ARM compiler installed. But the GNU-ARM toolchain can be installed via the menu: "Help | Install GCC ARM Compiler Tools..."


Eclipse-Based Code Composer Studio IDE with one of the projecs

The CCS IDE is based on Eclipse and for that reason it is painfully slow to launch and use. The Eclipse projects are threrefore difficult to share because they consist of multiple files and directories. Also, projects cannot be simply opened in the IDE but instead need to be "imported". The generated error messages are often confusing. Finally, debugging is slow and unstable.

Projects for the Course

This repository provides the project downloads that you can open in a specific embedded toolset and run on your PC at home. The projects are organized as illustrated in the following annotated directory tree:
