• Application: EEPROM Access Using Software I2C
• BSP Version: M480 Series BSP CMSIS V3.03.001
• Hardware: NuMaker-PFM-M487 Ver 3.0 + M487 Advance Ver 4.0

It is possible to use GPIO to emulate I2C function when the system needs more I2C multi-function pins than M480 can provide. This example code uses GPIO to emulate I2C to access an EEPROM.
