Made An Audio Recorder/Player From Scratch !
Demo of STM32F103C8 audio recorder/player made from scratch ! (SPI/DMA/SD/R-2R)
This is my university project. Writing/reading audio @ 44100Hz 8-bit resolution and saving recording as .WAV, storage: SD card via SPI (that was the most challenging part).
Took a few months of hard work and dedication but I learned a ton from this project !
Half a year I did not know anything about STM32 and knew very little about programming controllers in general (except Arduino) and hey... now I finished building my crude .wav player/recorder completely from scratch ! Feeling excited and overwhelmed, there's really no limits of what you can do as far as controllers go...
