Hello, my name is Renan and i need to port the project ESP32 Classic to ESP32 C3. This project use the microfone INMP441 and i need implement the FFT and Filter IIR , but i received some error in functions that use ESP-DSP library, i need confirmed the ESP32 C3 could use this ...
1. **ArduinoFFT**:这是一个Arduino库,可以用于实现快速傅里叶变换(FFT)。虽然它不是专门为ESP32设计的,但是您可以在ESP32上使用Arduino开发环境来运行这个库。 GitHub链接:https://github.com/kosme/arduinoFFT 2. **arm_math**:这是ARM公司提供的一套数学库,包括FIR和IIR滤波器等数字信号处理功能。ESP32使...
