SPI Communication Between STM32 and Arduino

This repository contains the source code and documentation for SPI Communication Between STM32 and Arduino, where an STM32F410RB microcontroller acts as the SPI master, transmitting data to an Arduino slave upon a button press. The project focuses on low-level peripheral driver development and signal validation using a logic analyzer.

Features

• Custom GPIO and SPI Drivers: Designed and developed from scratch, configuring low-level registers for precise control over I/O and serial communication.
• SPI Communication: Implemented and tested communication between STM32 (master) and Arduino (slave), integrating a logic level shifter for voltage compatibility.
• Button-Controlled Data Transmission: Data is sent over SPI when a button is pressed on the STM32 board.
• Signal Analysis: Verified and analyzed SPI signal integrity using a logic analyzer, ensuring correct timing, data transmission, and synchronization.

Components Used

• STM32 Nucleo Board (STM32F410RB).
• Arduino Board.
• Logic Level Shifter (3.3V to 5V conversion).
• Breadboard and Jumper Wires.

Tools Used

• STM32CubeIDE: For writing, compiling, and uploading the code.
• Logic Analyzer: To capture and analyze SPI signals.

Project Structure

• Source Code: C code for GPIO, SPI driver, and button-controlled data transmission.
• Signal Captures: Logic analyzer outputs verifying SPI timing and synchronization.
• Project Photograph: Details on implementation and setup.
