App note on utilizing the built-in DAC on your STM32 micro.

This application note gives examples for generating audio output signals using the Digital to Analog Converter (DAC) peripheral embedded in the STM32F10xx microcontroller family.

The STM32 DAC module is a 12-bit word converter, with two output channels for supporting stereo audio.

The DAC can be used in many audio applications such as: security alarms, Bluetooth headsets, talking toys, answering machines, man-machine interfaces, and low-cost music players STM32 DAC can also be used for many other analog purposes, such as analog waveform generation and control engineering.

  1. Wow, this is literally the best timing ever. Yesterday I got the idea of building a waveform generator with my STM32L-Discovery but I had no idea how. Honestly going from Arduino to ARM isn’t the easiest thing, but hell, it is fun. Does anyone here have some other resources for me that teach the ARM-Cortex M3? That would be awesome.

    Excellent book about the ARM core.

    He’s got one for M4 also…
