esp32-firmware-engineer

ESP32 firmware engineering for ESP-IDF projects. Write, review, and debug embedded C/C++ code involving FreeRTOS tasks/queues/timers, GPIO/I2C/SPI/UART/ADC/PWM peripherals, TWAI/CAN, Wi-Fi/BLE networking, OTA updates, Secure Boot and flash encryption, LVGL display integration, build/flash/monitor workflows, logging, crash analysis, memory/code-size optimization, low-power sleep/wakeup design, on-device USB/serial service terminals, and board bring-up. Use when an agent is asked to implement ESP-IDF firmware features, review embedded changes for correctness or race conditions, investigate boot/runtime failures or Guru Meditation panics, interpret serial logs, fix build/link/flash problems, optimize RAM/flash usage, tune deep sleep/light sleep behavior, harden firmware for production, add a service console/CLI, integrate a display with LVGL, or diagnose hardware-software integration issues on ESP32-class devices.
