# Modern Embedded Systems Programming Course for ARM Cortex-M > QuantumLeaps' modern-embedded-programming-course combines a free C video course with ARM Cortex-M lesson projects. It covers machine-level execution, interrupts, RTOS, state machines, and active objects, but hands-on study depends on compatible hardware and vendor tools. **QuantumLeaps/modern-embedded-programming-course** — Companion repository to the "Modern Embedded Systems Programming" video course. - Repository: https://github.com/QuantumLeaps/modern-embedded-programming-course - Website: https://www.youtube.com/c/StateMachineCOM - Stars: 1,547 · Forks: 236 - Language: C - License: AGPL-3.0 - Published: 2026-10-16 · Updated: 2026-10-16 · Language: en - Canonical page: https://hysenlabs.com/projects/quantumleaps-modern-embedded-programming-course ## What the Modern Embedded Systems Programming Course Covers QuantumLeaps' modern-embedded-programming-course is the companion repository for the Modern Embedded Systems Programming video course. It is aimed at developers who want to learn embedded C while understanding what the processor, startup code, interrupts, and peripheral interfaces actually do. The README presents the course as free and practical, with an emphasis on learning by doing rather than treating embedded software as a collection of vendor API calls. The syllabus begins with binary representations, two's complement, hexadecimal notation, flow of control, status registers, and branch instructions. It then moves through variables, arrays, pointers, GPIO, bitwise operations, functions, recursion, and the call stack. Later subjects include the ARM Procedure Call Standard, standard integer types from stdint.h, structures, CMSIS, startup code, the vector table, and the linking process. The later syllabus covers interrupts, race conditions, superloop architecture, RTOS, object-oriented programming in C, event-driven programming, active objects, hierarchical state machines, automatic code generation, software tracing, assertions, and Design by Contract. That range makes the course a long learning path rather than a reusable software library. Learners should expect separate lesson projects and concepts, not one installed package with a single application programming interface. ## Machine-Level Learning for ARM Cortex-M The course repeatedly connects C code to the behavior of an embedded microcontroller. Its listed concepts include status registers, branch instructions, function calls, the call stack, startup code, vector tables, interrupts, and linking. This is the central difference between this repository and a course that only demonstrates how to call a vendor's peripheral API. The documented target is ARM Cortex-M. The main board used throughout the course is the Texas Instruments TivaC LaunchPad, also identified as EK-TM4C123GXL, based on an ARM Cortex-M4F microcontroller. According to the README, the board includes a built-in Stellaris ICDI hardware debugger and programmer for single-step debugging and inspection of internal state. The downloadable course projects also include versions for the STM32 NUCLEO-C031C6, based on an ARM Cortex-M0+ MCU. That board includes an ST-Link debugger. The two supported targets give learners some choice, but they do not establish support for every Cortex-M board. The README does not document a portable build process for arbitrary hardware, so adaptation outside the named targets would require separate engineering work. ## Lesson Repositories and Progression of Material The repository layout follows the course sequence. Its top-level entries include lesson-01 through lesson-49, followed by lesson-51 through lesson-56, along with a resources directory. There is no lesson-50 directory in the listed repository contents. This organization gives learners a direct way to associate code with the corresponding part of the video course. Based on the README's syllabus, the course progresses from foundational C and machine-level topics toward interrupts, race conditions, superloop architecture, RTOS, and more structured software designs. Event-driven programming, active objects, hierarchical state machines, tracing, and assertions appear after those foundations. That ordering has a practical rationale. A learner studying event handling can connect hardware interrupts and asynchronous execution to the organization of an event-driven application. The repository does not document one installation command that configures every lesson. There are also no GitHub releases. Users therefore need to select a lesson project and the board version that matches their setup. The README says projects are available through the course downloads, but it does not specify a release tag, migration script, or compatibility matrix for every lesson and vendor tool version. ## Hardware and Toolset Constraints The repository is designed for hands-on practice. Several early lessons use a simulator, so a physical board is not required at the beginning. The README states that later lessons which interact with MCU peripherals, including GPIO, require an embedded board. A learner can therefore begin with simulation and move to physical hardware after the lessons start exercising real peripherals. The primary board is the TivaC LaunchPad based on an ARM Cortex-M4F. The project downloads also contain versions for the STM32 NUCLEO-C031C6 based on an ARM Cortex-M0+. The README calls both boards inexpensive and self-contained. Their integrated debuggers support single-step execution and inspection of internal state, which fits the course's focus on understanding execution below the C-language level. The documented build tools are IAR Embedded Workbench for ARM and KEIL MDK. IAR is used in lessons 1 through 19. The README notes that IAR no longer offers the former free, size-limited KickStart license and describes a two-week evaluation license instead. It also states that the early IAR projects have been updated to newer toolset versions. The README does not document a single board driver installation procedure or a universal command for configuring either target. ## Starting the Course with a Board-Specific Project There is no package-manager installation for this repository because it is not distributed as a conventional C library. The README directs learners to the course projects and the Modern Embedded Systems Programming video playlist. Installation therefore means obtaining the appropriate project files and installing the vendor toolset named for that lesson. Begin with an early simulator-based lesson and open the associated lesson directory or download. The README does not provide a universal shell command for doing this, so no repository or tool version should be invented. When the course reaches GPIO or another peripheral, choose the project matching the board you own. For the primary path, use the TivaC LaunchPad project based on an ARM Cortex-M4F. For the alternative path, use the STM32 NUCLEO-C031C6 version based on an ARM Cortex-M0+. Before starting, compare the lesson project with the board model, debugger, compiler, and vendor SDK listed in the relevant documentation. If a project does not open or link, the README does not identify a universal repair procedure. First confirm that the selected project belongs to the correct board and toolset. The repository also does not document rollback behavior for compiler or SDK upgrades. ## How the Course Differs from a Vendor SDK A conventional vendor SDK usually provides board definitions, peripheral drivers, linker scripts, startup files, build configurations, and a debugger integration for a defined family of microcontrollers. This repository does not present itself as a replacement for that kind of support package. Its purpose is to teach the concepts required to understand and design embedded software. That approach is useful for developers who can already call peripheral APIs but want a stronger model of startup behavior, interrupt handling, race conditions, and software architecture. The inclusion of superloops, RTOS, event-driven programming, active objects, and hierarchical state machines gives the course a broader scope than register-level instruction. The tradeoff is that the course is less plug-and-play than an SDK. Projects depend on documented targets and vendor toolsets, and the README does not promise board-independent builds. A product team may still need a supported SDK, reproducible builds, device-specific drivers, and integration testing. The repository is better treated as a structured education path than as a production platform component. ## AGPL-3.0 Licensing and Maintenance Boundaries The repository uses the AGPL-3.0 license. Any organization considering reuse or redistribution of lesson code should review that license's requirements with its own legal process. This article does not interpret whether a particular classroom, internal, hosted, or commercial use satisfies the license. The repository is not archived, and its last push was on 2026-07-07. There are no GitHub releases. The README mentions updated IAR project versions, but it does not define a release schedule, support window, or consistent upgrade policy for every lesson directory. That absence matters for adoption because a newer compiler, SDK, or board support package may affect old project files. The repository fits individual learning, guided coursework, or technical onboarding where participants can follow the lessons and handle toolchain-specific differences. It fits less well when an organization requires one supported release, guaranteed compatibility across devices, or a vendor-backed maintenance commitment. The first verification is project alignment: confirm the selected lesson, target board, compiler, debugger, and SDK before treating it as an organization-wide development baseline. ## Conclusion Adopt this repository if you want a structured, video-supported path through embedded C and ARM Cortex-M, especially if you can use the documented TivaC or STM32 hardware. Do not treat it as a complete toolchain or a substitute for general C study. Verify first that the lesson, board, compiler, debugger, and vendor SDK match, because the repository has no GitHub releases or documented release-based upgrade path. ## FAQ ### What is the Modern Embedded Systems Programming Course?
