Hello, I need comunicate with EEPROM, 24, 93 and 95 series EEPROM.
My micro is STM32F103, there is no I2C, SPI pin free to use.
I will emulate these protocol I2C, SPI and Microwire on GPIO pins, always with the same pins, which will have to emulate the protocols.
You know libraries or examples that make these?

Thank you so much!
