I2C configuration

Hi,

In our project I2C1 (PTD9 & PTD6) used for EEPROM communication. I2C1 (PTC6 &PTC7) used for RTC communication. Is it possible to configure the same instance twice in single master?

Thank you

Hi @LavanyaR

only one master configuration structure can be used at a time. Let me copy here from the user manual:

So, there are two options if more slave devices with different settings are used - either deinit and init the driver each time when you need to switch the configuration or set the baud rate and address in runtime as mentioned in the manual.

If you have the slave devices connected to different pins, it will be even more complicated - you need to change also GPIO configuration. So, deinit and init makes more sense here.

Lukas
