🛠️ Highlights

• Host Programs: Data types, bitwise manipulation, pointers, data alignment & packing, structures, unions, preprocessor macros.
• Target STM32F407 Projects: Peripheral register access, GPIO configuration, interrupt service routines (ISR), volatile qualifiers, bitfield-based register manipulation, and keypad interfacing.
