Detailed Description

template<typename I2cMaster>
class modm::Cat24Aa< I2cMaster >

I2C Eeprom CAT24AA

Driver for OnSemi CAT24AA Eeprom. I2C eeprom with an 11-bit address pointer, encoded in 3 bits of the device slave address plus the address byte. Base address is fixed to 0x50.

Member Function Documentation

void modm::I2cDevice< I2cMaster, 10 , cat24Aa::DataTransmissionAdapter >::attachConfigurationHandler ( I2c::ConfigurationHandler handler )

inheritedinline

Attaches a configuration handler, which is called before a transaction, whenever the configuration has to be changed.

bool modm::I2cDevice< I2cMaster, 10 , cat24Aa::DataTransmissionAdapter >::isTransactionRunning ( )

inheritedinlineprotected

Returns: true when transaction is busy.

modm::ResumableResult<bool> modm::I2cDevice< I2cMaster, 10 , cat24Aa::DataTransmissionAdapter >::ping ( )

inheritedinline

Return Values

true	device responds to address
false	no device with address found

template<typename I2cMaster >

template<typename T >

modm::ResumableResult<bool> modm::Cat24Aa< I2cMaster >::read	(	uint16_t	address,
		T &	data
	)

inline

Convenience function

Shortcut for:

return read(address, static_cast<uint8_t *>(&data), sizeof(T));

void modm::I2cDevice< I2cMaster, 10 , cat24Aa::DataTransmissionAdapter >::setAddress ( uint8_t address )

inheritedinline

Sets a new address of the slave device.

Parameters

address the slave address not yet shifted left (address < 128).

bool modm::I2cDevice< I2cMaster, 10 , cat24Aa::DataTransmissionAdapter >::wasTransactionSuccessful ( )

inheritedinlineprotected

Returns: true when transaction did not return an error.

template<typename T >

modm::ResumableResult<bool> modm::Cat24Aa< I2cMaster >::write	(	uint32_t	address,
		const T &	data
	)

inline

Convenience function

Shortcut for:

return write(address, static_cast<const uint8_t *>(&data), sizeof(T));

template<typename I2cMaster >

modm::ResumableResult<bool> modm::Cat24Aa< I2cMaster >::write	(	uint32_t	address,
		const uint8_t *	data,
		std::size_t	length
	)

Write block

Parameters

address	Address
data	Data block
length	Number of bytes to be written

Returns: true if the data could be written, false otherwise

template<typename I2cMaster >

modm::ResumableResult<bool> modm::Cat24Aa< I2cMaster >::writeByte	(	uint32_t	address,
		uint8_t	data
	)

inline

Write byte

Parameters

address	Address
data	Data byte

Returns: true if the data could be written, false otherwise
