[En-Nut-Discussion] External I/O and I2C on available port of Ethernut 1

[Berns J. Buenaobra]

Hello group:

If you can't use PORTA, PORTC and PORTE bit 5 is used by the Ethernet
interrupt while PORTF bits 4-7 are blocked, if the JTAG fuse
is enabled. Where could I possibly interface an external hardware like
an external Flash/EEPROM or RAM or any device for that matter and
possibly perform a I2C memory/data transfer to and fro the Ethernut 1
board?

How can this be done?

Thanks,

Berns B.
