Resolved! Using STM32F723 I2C with multiple slaves at different voltages

Dear ST Microelectronics Team,I want to connect a STM32F723IE with I2C as master, which is powered with 3.0V, to a bus with one slave with 3.0V and to another slave with 3.8V. From the datasheet I can see that the GPIOs are 5V compliant, but can the ...

Any easy way to find out after WFI() if device did sleep?

Is there an easy way to find out after the WFI() instruction if the device did really sleep? Using stop modes, the device will have switched clock to HSI/MSI. Setting the clock to the state before sleep is some effort and could be omitted, if sleep...

How to properly configure ADC injected group?

Hello, I've tried to use ADC for two Potentiometers only with injected group conversion but couldn't make it work. I'm using STM32F446RE. I couldn't find solution so I'm asking here. Previously I read their value correctly via polling and I know that...

Where can I find the relation between the OSPEEDR register different value (Low, Medium, High and Very High) and the frequency of the signals I want to use?

Hello ST Microelectronics community,I'm using a STM32H743ZI and I'm currently working on configurating properly the different I/O I want to use.To do so I need to set the set the pull up/down, open drain,etc. And also the speed mode.I could not find ...
