Design of Fir Filter Based on STM32 Microcontroller
A high-order FIR filter algorithm was implemented using the STM32F103CBT6 microcontroller.Firstly,complete the FIR filter design using MATLAB and transplant the filter algorithm onto a microcontroller.Then,the brainwave signal was sampled and the data was filtered by the FIR filter,and the filtered data was correlated to MATLAB for time-domain and frequency-domain analysis.The results have shown that using software designed and implemented FIR filters is beneficial for improving the anti-interference performance of brain computer devices.
