9 * \brief Generic library to handle buzzers and leds
13 * \author Giovanni Bajo <rasky@develer.com>
18 * Revision 1.4 2004/07/30 14:15:53 rasky
19 * Nuovo supporto unificato per detect della CPU
21 * Revision 1.3 2004/07/14 14:04:29 rasky
22 * Merge da SC: spostata bld_set inline perché si ottimizza parecchio tramite propagazione di costanti
24 * Revision 1.2 2004/06/03 11:27:09 bernie
25 * Add dual-license information.
27 * Revision 1.1 2004/05/23 18:36:05 bernie
28 * Import buzzerled driver.

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