Universal I2C & SPI EEPROM Flasher using Android and PIC16F628A

Universal I2C & SPI EEPROM Flasher on Android using a PIC16F628A Bridge

Reading and writing configuration EEPROMs (such as automotive modules, TV motherboards, or industrial sensors) is a routine task in electronics repair.

OTG Flash EEPROM turns an Android smartphone into a universal memory reader and writer, utilizing a Microchip PIC16F628A as an intelligent USB-to-I2C/SPI hardware bridge.
