MICA Sounder
[Device Drivers]

Defines
#define	dev_open_DEV_MICA2_SOUNDER()   mos_mutex_lock(&sounder_mutex)
	gain an exclusive lock on the Sounder. Any other threads calling dev_open_DEV_MICA2_SOUNDER() will block until the owner calls dev_close_DEV_MICA2_SOUNDER().
#define	dev_close_DEV_MICA2_SOUNDER()   mos_mutex_unlock(&sounder_mutex)
	release exclusive lock on the Sounder. Any other thread blocking on dev_open_DEV_MICA2_SOUNDER() will now unblock.
Functions
uint16_t	dev_read_DEV_MICA2_SOUNDER (void *buf, uint16_t count)
	not supported for the MICA2 Sounder.
uint16_t	dev_write_DEV_MICA2_SOUNDER (const void *buf, uint16_t count)
	Cause the sounder to be turned on or off. If the value of buf[0] is 0x00, the sounder is turned off. Any other value will turn it on.
uint8_t	dev_mode_DEV_MICA2_SOUNDER (uint8_t md)
	not supported for the MICA2 Sounder.
uint8_t	dev_ioctl_DEV_MICA2_SOUNDER (int8_t request,...)
	not supported for the MICA2 Sounder.
Variables
mos_mutex_t	sounder_mutex
