Unified Build System (base.mk)

To ensure consistent optimization and hardware acceleration across all projects, I utilized a shared Makefile logic.

⚙️ Compiler & Linker Configuration

  • Optimization: -O0 is used for debugging clarity and register-level visibility.
  • FPU Acceleration: Flags -mfloat-abi=hard and -mfpu=fpv4-sp-d16 enable the hardware FPU.
  • Standard Library Management: Used -nostdlib but explicitly linked -lm (math) and -lgcc (helpers) to support floating-point to integer conversions.

🛠 VPATH Strategy

The build system uses a VPATH to pull in shared drivers automatically: ```makefile COMMON_SRCS = startup.c uart.c i2c.c dma.c hts221.c
