hello, I am working in a project with STM32f100 and I want to set this MCU as a slave using I2C interface. the master should be raspberry PI so I need the address of STM32.

You need to configure the address in the I2C register, I2C_OAR1 or I2C_OAR2. More info in RM0008.

I have configured a slave address in CUBEMx, but when I open my raspberry and try to detect I2C signal, I can't see any thing. any suggestions?

what code is loaded to the STM32? Try some example from the Cube Introduction package. There are several examples of I2C communication.
