This EEPROM is unique because it has an EUI-48 MAC address programmed into the EEPROM, which is convient for creating internet connected devices with valid MAC addresses.
The FTDI example uses a FT232H USB to SPI device to develop the drivers without the use of a microcontroller.
One-time device setup instructions can be found in the libftd2xx crate.
With the adafruit FT232H breakout create the following connections:
- Connect SCK to D0
- Connect MOSI to D1
- Connect MISO to D2
- Connect CS to D3
- Connect Vdd to 3.3V or 5V
- Connect Vss to GND
Run the example with
cargo run --example ftdi.
