📉 Real-Time Low-Pass FIR Filter for Accelerometer Data

This project implements a real-time low-pass FIR filter using a Hamming window to process motion data from a 3-axis accelerometer. Designed for embedded systems, the filter runs on an STM32 microcontroller using the CMSIS-DSP library for efficient, high-performance signal processing.

🎯 Objectives

• Filter high-frequency noise from accelerometer data using a FIR filter.
• Implement the filter in real-time on an STM32 MCU using CMSIS-DSP.
• Acquire data via I2C from the sensor and send filtered output over UART.
