The embedded engineer roadmap.

The path from your first line of code to senior firmware skills, phase by phase. Each card is a course, and your progress turns it green automatically.

1

Programming Foundations

Start here. Learn to think like a programmer: variables, logic, loops, and functions.

Beginner

Programming Fundamentals

A beginner pre-req: variables, control flow, functions, arrays, and recursion in C — the bedrock before the embedded modules.

2

The C Language

C is the language of embedded. Master pointers, memory, structs, and bit manipulation.

Intermediate

C Programming

Pointers, dynamic memory, the compilation pipeline, and undefined behavior — the rigorous core-C skills every firmware interview probes.

3

Computer-Science Toolkit

Round out your programming with the data structures, algorithms, and C++ features that earn their keep on a constrained device.

Intermediate

Data Structures & Algorithms

Big-O, ring buffers, linked lists, hash tables, state machines, search and sort — through the embedded lens of fixed memory and no heap.

Intermediate

C++ for Embedded

Classes, RAII, templates, and zero-overhead abstraction — the C++ subset that's idiomatic on microcontrollers, and what to leave off the chip.

4

Embedded Hardware

Meet the microcontroller: the memory map, registers, GPIO, interrupts, timers, and analog peripherals.

Intermediate

Embedded Systems Fundamentals

MCUs from the silicon up: memory maps, registers and memory-mapped I/O, GPIO, interrupts, timers, PWM, ADC/DAC, clocks, watchdogs, and the boot sequence.

5

Peripherals & Real-Time

Talk to other chips over UART, SPI, I2C, and CAN, then run many tasks at once with an RTOS.

Intermediate

Communication Protocols

How chips talk: UART, SPI, I2C, and CAN at the wire and register level — timing diagrams, tradeoffs, and the pull-up/baud/contention bugs that bite every bring-up.

Advanced

RTOS & Real-Time Concepts

Tasks, scheduling, and context switching; mutexes, semaphores, and queues; priority inversion, deadlocks, and hard-vs-soft real time — with a practical FreeRTOS tour.

6

Debugging & Connectivity

Pick up the pro tooling to find bugs on real hardware, then get your device onto the network.

Intermediate

Debugging & Toolchain

The compiler/linker/loader toolchain, makefiles and linker scripts, GDB and on-chip debugging (JTAG/SWD), breakpoints, logic analyzers, logging, and reading a datasheet.

0/9 lessonsStart
Advanced

Networking & IoT

From the OSI model to TLS: Ethernet, IP, TCP/UDP, sockets, and the IoT protocols (MQTT, CoAP, BLE/WiFi) that connect constrained devices to the internet — securely.
