Hierarchical State Machines Masterclass - From the Ground Up to Production
Develop HSM driven firmware in embbedded C with enterprise rigor - MISRA practice, deterministic logs, and golden traces.

This course teaches you to model behavior using statecharts and to implement hierarchical state machines in embedded c.
You will learn a professional approach that maps requirements to code, produces deterministic logs for audits, and keeps complex products maintainable over years.
What this skill actually is
Statecharts are a rigorous way to describe how a device behaves over time. They extend flat finite state machines with hierarchy, entry and exit actions, guards, internal transitions, history, and orthogonal regions.
In practice this means you express product behavior as states and events, then implement it as a HSM micro kernel plus a clean transition table. The result is code that is easy to reason about, easy to test, and easy to change when requirements evolve.
Why Top Company Teams Care
Traceability end to end. Requirements link to states, events, and actions. Actions link to logs and tests.
Determinism. Run to completion dispatch and timebase produce repeatable behavior and golden traces for QA and compliance.
Maintainability at scale. Superstates eliminate duplication and orthogonal regions prevent state explosion.
Audit readiness. MISRA C 2012 subset, no heap policy, versioned model artifacts, and numeric SWO or UART logs.
How this is different from mastering an RTOS or Design Patterns
RTOS mastery focuses on scheduling threads and sharing resources. Statecharts focus on modeling and controlling device behavior through events.
You can run statecharts with or without an RTOS. This course shows the RTOS free path first, which is ideal for many embedded products at top companies.
Design patterns are reusable, well-established solutions at the code level, such as Strategy or Observer, that help structure interactions and behaviors within components.
Statecharts are an architecture level method that defines the overall shape of behavior. Patterns can live inside actions, but statecharts tell you when and why those actions run.
AUTOSAR or a specific OS gives you a platform checklist. Statecharts give you a product behavior model that stays stable even if the platform changes. That is why large companies pair an OS with a state based design.
What makes this course unique
Pure Embedded C. Direct register programming.
Model artifacts live in the repo as text. State Catalog, Event Dictionary, Transition Table, Invariants, and Golden Traces.
A Hierarchical State Machine (HSM) micro kernel you fully understand. You will write it, test it, and extend it.
Enterprise rigor throughout. Coding standards, review checklists, deterministic logs, and acceptance criteria per module.
What you will learn
Express product behavior with the vocabulary of statecharts. Events, guards, entry and exit actions, internal transitions, hierarchy, history, and orthogonal regions.
Implement a compact HSM kernel in C that enforces run to completion and clean transition choreography.
Build an event driven MCU architecture. ISR posts events, queue feeds dispatcher, timers post timeouts, actions do work.
Achieve practical compliance. Apply a pragmatic MISRA C 2012 subset that fits an HSM based design.
Prove behavior. Generate golden traces, replay them in host tests, and tie them to requirements.
What you will build on hardware
A multi mode device on microcontrollers with hierarchical states.
Event queue and timer service with deferred events and bounded retries.
Robust update flow with CRC checks and recovery to Active.
Telemetry and command processing that run in parallel regions without an RTOS.
Deterministic logging over serial that decodes into human readable traces.
Outcomes you can take to work and interviews
You can convert a messy switch-case state machine into a clean hierarchical design that passes peer review.
You can explain, with code and logs, why a transition occurs, what resources are configured on ENTRY, and what is canceled on EXIT.
You can hand auditors a short set of text files plus golden traces that exactly describe device behavior.
You can ship MCU code that is predictable, testable, and easy to extend. That is what managers at large companies pay for.
Who this is for
Intermediate embedded engineers who can write drivers and want to master complex logic without an RTOS.
Team leads who need a maintainable architecture for multi year products.
Candidates preparing for interviews where you must explain system behavior, not only drivers.
