Explore the intricacies of building standalone music devices in this 50-minute conference talk from the Audio Developer Conference (ADC22). Delve into fundamental bare metal concepts for embedded audio programming, including serial communication protocols like MIDI, direct memory access, serial audio interfaces, and general purpose input/output. Using the Daisy platform as a context, gain insights into analog electronics, circuitry prototyping, and various types of embedded software development. Learn about the Electrosmith Daisy Seed, MIDI circuitry, UART, GPIOs, multiplexing, DMA, SAI peripherals, and digital-to-analog conversion. Ideal for embedded-curious audio software developers interested in creating digital synthesizers, guitar pedals, and other noisemakers.
