My project implements a tilt measurement system using an FPGA and a 3-axis ADXL345 accelerometer, enabling real-time inclination angle computation. The system uses a hybrid hardware-software approach, where the FPGA performs high-speed processing, while the Hard Processor System (HPS) handles communication and control via memory-mapped I/O in C++. The FPGA converts raw acceleration data into angles between 0° and 180°, displaying the results on a 7-segment display and sending them back to the HPS for terminal output. A custom hardware module (angle_calculator) in Quartus Prime performs tilt angle calculations, ensuring ±1° accuracy and a 20ms response time. Using interrupt-driven processing, the design optimizes real-time sensor data handling while reducing CPU overhead, making it highly efficient for embedded applications.
