Hello,

I'm using SPI to dialog with an external chip (specific ADC). I'm using SDK functions.

At some point, to check if conversion is done, I have to keep CS low and check SDI level after sending a command. The question is :

  - Can I read the SDI signal as a standard GPIO ?

Thank you for supporting 

Franck
