Need simple code on i2c for stm32f051

Hi, it is possible to detect last code line before reset IWDG MCU?

I have FW with implementation 2 uart IT, I2C, FATFS, MSC etc. If I do not use IWDG everything is good, works fine I tested it 72 hour without freezing or other problems FW is worked smooth.But if I set IWDG after few hours running (4-8h) IWDG reset M...

I've got some S/W running on the STM32L432KCU6 on a NUCLEO-L432KC and couldn't get it into stop mode, or at least it seemed to come out immediately so the next step was to try the NUCLEO-L432KC example programs PWR_STOP1_RTC and PWR_STOP2_RTC. Neithe...

How can I calculate the clock frequency and Baud rate from code

I have an heavily modified LCD Application/example for STM32F746 Discovery and Usart code from CubeMX. It looks like their clock frequencies do not match, that is the Baud rate is off. I would like know in which files is the clock frequency set up. A...

Use tabs instead of spaces when generating files in cubemx

Hi, I recently installed the cubemx software, and while learning the program I saw in the code files that the indentation was space based and not tabs based. Is there any option to change the indentation style? I can't find any option like this in th...
