Partial Writes to an EEPROM | Cypress Semiconductor
Partial Writes to an EEPROM
The EEPROM component in PSoC Creator allows only to write one row (16 bytes) at a time to the EEPROM. There is no provision to write less than 16 bytes to specific EEPROM locations. For partial writes, we can read the complete EEPROM row into a RAM array, modify the desired locations and write the array back to the RAM.
Attached is an example project that shows how to perform a partial write to the EEPROM.
