Abstraction layer for EEPROM ICs like 25AA/25LC (SPI) and 24AA/24LC (I2C).

This library designed to work on top of ChibiOS/RT. It abstracts access to EEPROM like a regular file(s).

• The maximum capacity of EEPROM is 65536 bytes for 24AA and 24LC (a driver limitation).

• Include eeprom/eeprom.h file to your project.
• Customize eeprom/drvconf.h.
• Define a file object of type SPIEepromFileStream or I2CEepromFileStream and config structure for it.
• Retrieve low level eeprom driver descriptor by 'EepromFindDevice()'.
• Open it with EepromFileOpen() function.

Now you can access to EEPROM array like to a regular file with functions:

• chFileStreamRead()
• chFileStreamWrite()
• chFileStreamGetPosition()
• chFileStreamSeek()
• etc

Examples of usage and checking the returning parameter you can found in eeprom/eeprom_testsuit.c.

Based on 24aa project of ChibiOS/RT from Uladzimir Pylinski (aka barthess):
