The I2C interface in MACOBOX lets you dump data from EEPROMs and other I2C devices easily and safely.
You can use the I2C socket to connect to the Bruschetta Box.
Connecting to an I2C Device #
Use the I2C clip provided in your MACOBOX kit to connect to standard EEPROMs.
Make sure:
- The socket is well aligned with the EEPROM pins
- The chip is powered (either externally or via MACOBOX)
- No other devices are pulling the I2C lines
Make sure to select mode S1-> OFF, S2 -> ON
Starting an I2C Dump #
Once connected:
- Go to the I2C page
- Press Start I2C Dump
- A spinner will indicate progress
- Once complete, the data will appear in the Binaries section
From there, just like with SPI:
- Press Play to extract data from the dump
- Press USB to export the binary
- Associate the dump with a project
- Use Share to send it to the Cloud Scanner
Advanced Options #
In the Advanced section, you can:
- Name the dump file before saving
- Select the EEPROM size from a dropdown menu. Selecting the correct size ensures a reliable and complete dump
Tips #
- Make sure the clip is well positioned and the EEPROM pins are not oxidized
- Double-check the orientation: pin 1 is usually marked with a dot or notch
- Some boards may need to be unpowered during the I2C dump
- If the dump fails or returns only
FF, try changing the EEPROM size or verify the Vcc/GND connections - If available, consult the device’s datasheet for I2C address and memory size
