Reading and Programming I2C EEProms
Reading and Programming I2C EEPromsIntroductionThe Programming and Reading of I2C EEProms is one of the major uses of the I2C2PC and revised BL233C1(release 2017) adds dedicated I2C eeprom command K, whch makes theprocess much simpler. New applications should use BL233C, existing BL233B commands will stillwork correctly, there is no reason to change. If you have I2C2PC adaptors, you can replace the Addressing the eeprom I2C Address Pins .. Sequential Reads and Writes .. Table of EEProms .. I2C Address Pins, Page Sizes andWrite Times.
A good summary of using various I2C EEProms is Microchip’s “AN536 Basic Serial EEPROM Op-eration” 1. Addressing the EEProm Memory Space BL233Cs K command hides this complexity especially for large reads and writes. I2C EEProms have an internal address pointer. This must be written (an I2C write cycle) before data can be read or written.
