How to know the MCU address for its use as an I2C slave ?

HHUET.1

Hi guys,

I would like to connect two different MCU to each other through I2C.

One MCU would be the master, and the other one the slave.

How can I find the I2C addresses of these devices ?

I found the device ID in the reference manuals : 0x411 for STM32F207ZG and 0x499 for STM32F746. But it is larger than the requested 7-bit address !

Could you help me ?

Thank you in advance !

You select the address you want when you configure the I2C as a Slave
