Mixedsignal hardware design course: https://philslabshop.fedevel.education
How to set up firmware for I2S with DMA, ADCs with DMA triggered at a fixed sample rate by timers, basic driver for the audio codec, and how to efficiently process audio data using double buffering. "Precursor" to previous videos on realtime digital processing (DSP) of audio data using an STM32 microcontroller in C on custom audioprocessing hardware.
