🔥 Complete Course Roadmap

Think of the entire subject like an industry embedded-product journey:

UNIT-I
Requirements → Microcontroller → Embedded C

⬇️

UNIT-II
Testing → SRS → HAL → Drivers → Real-time firmware

⬇️

UNIT-III
UART/SPI/I²C/CAN → Device communication → Test cases → Bugs

⬇️

UNIT-IV
Debugging → Logs → Oscilloscope → Logic Analyzer → Firmware architecture

⬇️

UNIT-V
Bootloader → OTA → Automation → CI → QA → Release

🎯 In one line:

Requirement → Design → Code → Test → Communicate → Debug → Validate → Update → Release

This subject is particularly useful for embedded firmware/developer and embedded testing/QA interviews, because it connects your Embedded C + microcontrollers + communication protocols + debugging + testing knowledge into one workflow.
