No clock signal on SPI1_SCK

After configuring SPI1 in CubeMX and calling HAL_SPI_Transmit, I get a signal on the SPI1_MOSI line, but no signal on the SPI1_CK. I have confirmed that the pin is working correctly with other code and tried different clock speeds to see if that was ...

Resolved! STM32L1 ADC only clocked by HSI ?

Heyho,just checking the L162 for a new project, then found that the ADC can only be clocked by the HSI.Is that correct?If yes, why?My experience with HSI (and other RC-oscillators) is that it is "mediocre" at best, rather inaccurate and jitters like ...
