I2C Protocol of STM32F030R8T6

I am trying to interface 24LC256 EEPROM to my STM32F030R8T6 discovery board using I2C protocol. I am analyzing SCL and SDA pins using DSO. I can achieve a start operation and place device id on the line. I need to transfer two 8bit data successively....

Hello, on STM32H743 I noticed that the VCATCH bit in the DFSR register is set after a Power On Reset.

From the ARM manuals it seems that this register should read as '0' after an PORRST. I couldn't find any mentioning of this issue in the respective errata sheets. Is this an issue with the Cortex-M7 or with the specific implementation in STM32H743?Th...

Virtual comport in discovery board for printing hello world possible ??

With stm nucleo stm32476rg it was possible to print hello world into the terminal (via serial com port) and also it would show virtual com port in devices and printer information in properties.But with stm32l100rc it doesnot show the virtual comport ...
