I am trying to implement SPI master on my ESP32S2 board. However, I am facing problem with pin configuration for the same. In this regard, my question is can I use MTDI pin (Pin 46) as Chip Select? Please help with your responses. Thank you.
Please check Page 11 of this data sheet.
Pin 46 is MTDI
I note that you are using ESP32S2 but which board exactly ?
