use of SPI pins (GPIO6-GPIO11)

Postby colinives » Mon Oct 26, 2020 9:58 am

Hi there,

Looking at the reference information its suggesting that we cannot use GPIO6-11 due to those being used by the internal flash. Are there circumstances where these can be used for other SPI devices if we use a separate CS line when using another SPI device?

Thanks

Colin

I think you can if you have a very recent (close to master) ESP-IDF. There's a fair amount of limitations, however.
