Hey guys!

I have an issue with the SPI Interface of the STM32F401VB. To communicate with an ADC from LTC, I need to configure the SCK to stay high during idle time. Unfortunately the clock always starts low, see scope pictures. Where exactly is the problem? Do I need any pull up resistors or something ?

Thanks in advance for your help!
Best regards
