How to use the I2C communication between the X-NUCLEO-NFC08A1 and the NUCLEO F401RE

[Lukas3]

Hi,

i want to use the I2C Communication between the X-NUCLEO-NFC08A1 and the NUCLEO F401RE.

My Problem is that i don´t know what i have to change on the X-NUCLEO-NFC08A1, because there is default SPI communication.

Should i only add the resistors for the I2C or must i also remove the resistors for SPI communication.

Please help me how to use the I2C connection on the NFC08A1 board.
