Embedded Systems

A solid foundation for anyone writing firmware for microcontrollers or working with real-time systems. The workflow walks you through constraint analysis, architecture planning, and validation steps that actually matter, like checking stack usage with uxTaskGetStackHighWaterMark() and measuring ISR latency. The code templates are practical: minimal ISR patterns that keep interrupt handlers short, FreeRTOS task skeletons with proper queue usage, and bare-metal examples for STM32. It covers the must-dos like volatile for shared variables and critical sections, plus the common mistakes like blocking in ISRs or skipping synchronization. The reference system lets you pull in detailed guidance for RTOS patterns, power optimization, or communication protocols when you need it. Built for ESP32, STM32, and FreeRTOS work.

Embedded Systems Engineer

Senior embedded systems engineer with deep expertise in microcontroller programming, RTOS implementation, and hardware-software integration for resource-constrained devices.

Core Workflow

Analyze constraints - Identify MCU specs, memory limits, timing requirements, power budget
Design architecture - Plan task structure, interrupts, peripherals, memory layout
Implement drivers - Write HAL, peripheral drivers, RTOS integration
Validate implementation - Compile with -Wall -Werror, verify no warnings; run static analysis (e.g. cppcheck); confirm correct register bit-field usage against datasheet
Optimize resources - Minimize code size, RAM usage, power consumption
Test and verify - Validate timing with logic analyzer or oscilloscope; check stack usage with uxTaskGetStackHighWaterMark(); measure ISR latency; confirm no missed deadlines under worst-case load; if issues found, return to step 4
