Member Function Documentation

bool AT24CXX::is_ready ( )

virtualinherited

Return true(1) if the device is ready, write cycle is completed, otherwise false(0).

Returns

bool

Reimplemented from EEPROM::Device.

Definition at line 47 of file AT24CXX.cpp.

int AT24CXX::read ( void *  dest, const void *  src, size_t  size  )

virtualinherited

Read rom block with the given size into the buffer from the address. Return number of bytes read or negative error code.

Parameters

[in]	dest	buffer to read from rom.
[in]	src	address in rom to read from.
[in]	size	number of bytes to read.

Returns

number of bytes or negative error code.

Reimplemented from EEPROM::Device.

Definition at line 57 of file AT24CXX.cpp.

int AT24CXX::write ( void *  dest, const void *  src, size_t  size  )

virtualinherited

Write rom block at given address with the contents from the buffer. Return number of bytes written or negative error code.

Parameters

[in]	dest	address in rom to read write to.
[in]	src	buffer to write to rom.
[in]	size	number of bytes to write.

Returns

number of bytes or negative error code.

Reimplemented from EEPROM::Device.
