⚙️ From MCU boot → register-level control → real-world debugging

• Most resources are theory-heavy and not aligned with real firmware work
• Lack of clarity in:
  • MCU startup sequence
  • Linker scripts & memory layout
  • Debugging real embedded failures

• Explains bare-metal firmware from scratch → step-by-step
• Covers:
  • MCU boot process & startup code
  • Linker scripts (FLASH / RAM layout)
  • Register-level peripheral programming
  • Interrupt handling & NVIC
  • ADC (Polling vs DMA)
• Demonstrates real debugging scenarios and fixes

• Bridges gap between theory and production firmware development
• Helps engineers transition from:
  • High-level coding → low-level system understanding
• Structured like industry-grade firmware documentation

• Not just “how it works” → why it breaks & how to fix it
• Focus on edge cases, failures, and debugging mindset
• Built from hands-on embedded experience (not copied tutorials)

• Built a software-based simulation of an automotive CAN network
• Emulates multiple ECUs transmitting real-time CAN frames
• Developed a CAN analyzer for decoding and visualizing vehicle data
• Demonstrates:
  • ECU communication patterns
  • CAN message structures
  • Automotive system-level behavior

• Designed a +5V → +3.3V voltage regulation PCB
• Focused on:
  • Power efficiency
  • Stable voltage output
  • Component selection & layout optimization
• Implemented using Altium Designer

• Smart Lighting Automation System
  → Sensor-based adaptive lighting using real-time inputs

• Wearable Obstacle Detection System
  → Real-time obstacle alerts using ultrasonic sensing
