Hi,
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,
Omar

It appears that both chips could be driven from SPI (clock and data - chipselect still would need to be driven 'manually'), but it's up to you to work out the details.
