External DAC / ADC interface - STM32F7

I would like to use some external DACs and ADCs connected to my STM32F769 MCU.

The DACs (AD5512) and ADCs (ADS8320) have an interface with :

   + DIN : data input

   + CS : chip select

   + SCLK : clock for the data synchronization

My question is about how to interface with the SCLK signal and what is the best way to implement it. I guess the standard solution is to HIGH or LOW the output pin directly to simulate the clock but I would like to know whether there is another better or more professional solution for doing this using the STM32F7.


Thanks in advanced,
