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