Bill of materials

In this module we will use the following components:

  • STM32 NUCLEO-F072RB

  • USB cable - 6" A/MiniB

  • Adafruit I2S MEMS Microphone Breakout

  • Adafruit I2S Stereo Decoder

  • Jumper Wires

In principle, any board from STM32 can be used for these exercises, as long as it is supported by STM32CubeIDE, and exposes at least two I2S buses since both the microphone and the DAC (Stereo Decoder) require a dedicated I2S bus for audio transfers.

Prerequisites

  • basic knowledge of C and Python programming

  • a PC with a USB port (the microcontroller will be programmed and powered by your PC via a USB cable)

  • and, of course, having completed the the previous DSP modules!
