34 * \brief Generic library to handle buzzers and leds
36 * This library is divided into three different layers:
38 * - The topmost portable layer is buzzerled.[ch] which exposes a common API
39 * enable/disable the devices. Basically, it handles the asynchronism to
40 * implement bld_beep and bld_repeat.
41 * - The middle layer is CPU-specific and exposes a single main function which
42 * turns on/off each device.
43 * - The lower layer is board-specific and communicates with the middle layer
44 * with any required API. The idea is that devices can be tied to the CPU in
45 * many different ways (many different pins), so this part should describe
46 * which devices are present, and how they are connected.
