STM32 I2S ADC DMA & Double Buffering - Digital Audio Processing with STM32 #4 - Phil's Lab #55
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. "Pre-cursor" to previous videos on real-time digital processing (DSP) of audio data using an STM32 microcontroller in C on custom audio-processing hardware.
