firmware-testing

QEMU digital twin of Microchip dev boards and MikroE Click boards, checked against silicon: live board view, logic-analyzer timeline, fault injection, exact replay, VS Code extension, MCP (personal project)

Let your coding agent develop firmware on the real board, with the hardware as the gate.

Let your coding agent boot and test ESP32 firmware in a local emulator: MCP server, CLI and agent skill around esp32sim. No board, no account.

Hardware-in-the-loop regression testing for Flipper Zero firmware: two devices, one air gap, pass/fail JUnit for CI.

QEMU-based virtual router lab for Keenetic/Ported, Entware and KAS integration testing. Experimental, isolated and CI-driven.

Python + STM32 hardware-in-the-loop validation bench for testing embedded firmware with serial commands, sensor inputs, fault injection, latency checks, and automated pass/fail reports.

Python-based SSD/NVMe validation log analyzer for parsing test logs, detecting failures, classifying anomalies, and generating validation reports.

Lightweight unit-test framework for embedded C — assertions, mocks, virtual peripherals, and pluggable trace in pure C11 with a single-binary CLI

Binary-level emulator for embedded e-ink devices (ESP32-C3/S3 e-readers first): runs real firmware with cycle-level timing, realistic e-ink rendering, Wi-Fi/BLE, GDB and CI tooling. Desktop + Web.

ESP8266 emulator in C with an Xtensa LX106 interpreter, local web UI, GPIO/UART inspection and headless regression testing for compatible Arduino/NONOS SDK firmware.

Hardware, systems & test engineering portfolio (NDA-safe case studies)

FreeRTOS vibration-monitoring node for STM32F4: on-device FFT features and an int8 fault classifier over Modbus RTU, tested in CI on an emulated MCU.

A lightweight GUI for testing and debugging VCM firmware and its communication protocol.

Offline ultrasonic virtual laboratory with reproducible firmware/FPGA validation evidence. Silicon LogiX evaluation demo.

Test your firmware without a board — the Simantic Python SDK and pytest plugin
