9 * \brief Generic library to handle buzzers and leds
13 * \author Giovanni Bajo <rasky@develer.com>
18 * Revision 1.3 2004/07/14 14:04:29 rasky
19 * Merge da SC: spostata bld_set inline perché si ottimizza parecchio tramite propagazione di costanti
21 * Revision 1.2 2004/06/03 11:27:09 bernie
22 * Add dual-license information.
24 * Revision 1.1 2004/05/23 18:36:05 bernie
25 * Import buzzerled driver.

33 * an enumarator for each device, plus a special symbol NUM_BLDS containing the
39 /* Include hw-level implementation. This allows inlining of bld_set, which in turns
40 * should allow fast constant propagation for the common case (where the parameter
41 * device is a constant).
