In this project, the Bosch BMP280 sensor is integrated with an STM32 microcontroller using bare-metal, low-level register-based firmware. Communication is handled via I2C and SPI protocols. The firmware captures sensor data and outputs it to a 16x2 LCD display, demonstrating effective real-time data acquisition and display.

This is a Project is all about building bare-metal firmware for a Cortex-M4 STM32 microcontroller, using open source tools and libraries such as GCC and libopencm3. This starts from blinking an LED, to building a bootloader for performing firmware updates over UART/USB, to building a signed firmware security mechanism.

A minimal, no-HAL, bare-metal game for STM32F401CCU6 that draws to a 128×64 SSD1306 OLED over I²C (bit-banged) and uses a single push button on PA0 to “flap” a 3×3 dot through moving pipes

Minimal C implementation for button debouncing on STM32C031C6. Uses CubeMX only for SWD/debug and clock initialization. All GPIO configuration and toggling is done via direct memory-mapped register access.
