Hello! I’m Habib Rahman, an embedded systems and firmware engineer passionate about low-level software architectures, bare-metal C programming, real-time operating systems, and mixed-signal hardware design.

Embedded Coffe is my personal corner on the web where I document engineering notes, architecture deep dives, late-night hardware debugging sessions, and practical telemetry implementations.

What I Work On

• Bare-Metal & Microcontroller Firmware: Writing deterministic drivers and bootloaders from scratch for ARM Cortex-M (STM32, NXP), RISC-V, and ESP32.
• Real-Time Operating Systems (RTOS): Task scheduling, priority inversion mitigation, queue design, and memory protection using FreeRTOS and Zephyr.
• Marine & Industrial Telemetry: CAN Bus (CAN 2.0B / CAN-FD), NMEA 2000 (J1939 PGN handling), isolated transceivers, and robust IoT telemetry gateways.
• Mixed-Signal Hardware Design: Multi-layer PCB design in KiCad, ultra-low noise power supply rails for precision ADCs, and signal integrity considerations.

The Lab Bench

My daily engineering workflow revolves around hardware debuggers and measurement instruments:

• Debuggers & Probes: SEGGER J-Link, ST-LINK V3, Black Magic Probe
• Measurement: Rigol 4-channel Digital Oscilloscope, Saleae Logic Analyzer
• Toolchains & Languages: Modern C (C99/C11), C++, ARM Assembly, GCC/Clang, Make/CMake, Python for test automation
• EDA Software: KiCad for schematics and PCB layout

Connect & Collaborate

I’m always excited to connect with fellow embedded developers, hardware designers, and tinkerers:
