Empowering Engineers Through Open Research and Learning
PiEmbSysTech is more than a blog – it is an Embedded Systems and VLSI Lab built by practicing engineers. Our mission is to make advanced engineering concepts accessible, accurate, and implementation-ready. Each article and tutorial is developed through real project experience, ensuring that what you learn can be applied directly to industry challenges.
From microcontroller firmware and driver development to VLSI Design and Verification, our content focuses on experimentation, reproducibility, and continuous innovation.
Explore Our Core Learning Domains
At the PiEmbSysTech – Embedded Systems & VLSI Lab, you’ll follow curated paths across Embedded Systems tutorials, VLSI design and verification, AUTOSAR and automotive protocols, Linux drivers, RTOS, and IoT projects with microcontrollers.
Each domain blends theory with hands-on practice-firmware and Embedded C/C++, Python, bootloaders, device drivers, RTL/ASIC & FPGA flows, CAN/UDS/DoIP, and real-time scheduling with FreeRTOS or Zephyr.
Whether you’re prototyping on STM32/ESP32, building kernel modules on embedded Linux, or validating timing and DFT in silicon, our open, research-driven guides help you learn, innovate, and share production-ready engineering skills.


Learn from Real Projects, Designed by Engineers
Built in the PiEmbSysTech – Embedded Systems & VLSI Lab style, every project blends Embedded Systems tutorials with production practices: bootloaders, device drivers, and Linux drivers & RTOS development (FreeRTOS, Zephyr); protocol stacks for AUTOSAR and automotive protocols (CAN, UDS, DoIP, LIN); and silicon-side VLSI design and verification with RTL/FPGA/ASIC flows, STA and DFT.
You’ll also see Python, HIL, and IoT projects with microcontrollers (ESP32/STM32). Follow the design flow, run the code, and adapt the checklists to accelerate your own engineering builds.
