Function Documentation

bool _EEPROMwriteDummy	(	tSensors	link,
		long	address
	)

Perform a dummy write to set address for next read

Note: this is an internal function and should not be called directly.

Parameters:

link	the EEPROM
address	the address to set

Returns:

true if no error occured, false if it did

Definition at line 89 of file EEPROM-driver.h.

bool EEPROMreadBytes	(	tSensors	link,
		long	address,
		tByteArray &	data,
		int	numbytes
	)

Read a number of bytes from address

Parameters:

link	the EEPROM
address	the address to read from
data	the byte array to store read result in
numbytes	the number of bytes to read (limited to 16 at a time)

Returns:

true if no error occured, false if it did

Examples:

EEPROM-test1.c, and EEPROM-test2.c.

Definition at line 61 of file EEPROM-driver.h.

bool EEPROMwriteBytes	(	tSensors	link,
		long	address,
		tByteArray &	data,
		int	numbytes
	)

Write a single byte to address

Parameters:

link	the EEPROM
address	the address to write to
data	the byte array to write
numbytes	the number of bytes to write (limited to 13 at a time)

Returns:

true if no error occured, false if it did

Examples:

EEPROM-test1.c, and EEPROM-test2.c.
