AVR EEPROM
[Device Drivers]

Defines
#define	dev_open_DEV_AVR_EEPROM()   mos_mutex_lock(&eeprom_mutex)
	gain an exclusive lock on the AVR EEPROM Driver. Any other threads calling dev_open_DEV_AVR_EEPROM() will block until the owner calls dev_close_DEV_AVR_EEPROM().
#define	dev_close_DEV_AVR_EEPROM()   mos_mutex_unlock(&eeprom_mutex)
	release exclusive lock on the AVR EEPROM Driver. Any other thread blocking on dev_open_DEV_AVR_EEPROM() will now unblock.
Functions
uint16_t	dev_read_DEV_AVR_EEPROM (void *buf, uint16_t count)
	read count bytes from the current eeprom address into buf.
uint16_t	dev_write_DEV_AVR_EEPROM (const void *buf, uint16_t count)
	write from buf to the current eeprom address.
uint8_t	dev_mode_DEV_AVR_EEPROM (uint8_t md)
	not supported for the AVR EEPROM.
uint8_t	dev_ioctl_DEV_AVR_EEPROM (int8_t request,...)
	send an IO Control to the EEPROM Driver. Accepted parameters are: DEV_SEEK, [int16_t address]
Variables
mos_mutex_t	eeprom_mutex
