i have multiple slaves on an I2C bus on STM32F4. 


Since a "I2C_HandleTypeDef hi2c_x;" contains also fields like "DevAddress", do i need one HandleTypeDef per slave device on the bus or should they share one handle? Sorry if its a trivial question i just want to clarify whats the proper approach and couldnt find the answer in the HAL Driver description documents.


Thanks for your help,
