I2cEeprom

Description

The I2cEeprom object implements a driver for I2C-based EEPROMs, usually referred to as AT24 or similar. The data in the EEPROM can be mapped into the data property

This object was introduced in InCore 2.0.

Properties

data

This property holds a mapped data buffer containing the EEPROM data starting from dataAddress. It’s cached and only read again whenever dataAddress or dataSize are changed.

› Type:: ByteArray
› Signal:: dataChanged()
› Attributes:: Readonly

dataAddress

This property holds the address where to start reading data from the EEPROM.

› Type:: UnsignedInteger
› Default:: 0
› Signal:: dataAddressChanged()
› Attributes:: Writable

dataSize

This property holds the number of bytes to read from the EEPROM into the data property.

› Type:: UnsignedInteger
› Default:: 0
› Signal:: dataSizeChanged()
› Attributes:: Writable

Methods

read(UnsignedInteger startAddress, UnsignedInteger bytes)

This method reads – starting from a given address – the specified number of bytes from the EEPROM.

› Returns:: ArrayBuffer
