STM32F105 I2C clock streaching

Hi,We are working with the STM32F105 chip and we want to use its I2C interface to communicate with a chip that demanding an I2C master that allows the clock stretching. We need to know if it is possible to enable this feature in the STM32F105 and how...

Problem with STMH7 RTC using 32768Hz LSE clock gains time

We have our own STM32H743II board with a 32768Hz LSE crystal and proper caps as specified in app note AN2867. We have configured PC13 to output a 1Hz signal. We then used that to gate a frequency counter that is reading a precision calibrated 10MHz s...
