Configure SPI or I2C for continuous clock

In our STM32L5 based design we are using HSI16 to drive some clocks (SPI1). one way to route HSI16 clock is through MCO. is there any other way we can route this clock. 1. Can we configure I2C or SPI1 to route its clock on some GPIOs ?2.Continuous wr...

Hi, I am using STM32L4P5 discovery kit to find out current consumption in different ADC configuration, i.e 12 bit, 14 bit & 16 bit resolution achieved using oversampling. May I know why the current consumption is same in different ADC configuration

Above table shows the observations made. I would like to know if there is any internal architecture of MCU which is governing same current consumption.I have attached code snippet for 14 bit configuration.References: User Manual UM2651: DataSheet: ST...

Resolved! STM32F100 ADC Sample Rate

The datasheet and ref manual only mention that the conversion time is 1.2 us but this is not enough to find the sample rate. All other stm32 products mention that explicitly, why not this one?
