GPIO as CS for SPI
GPIO as CS for SPI
Do you see any issue with using GPIOs as chip-selects for SPI devices if number of regular CS pins is not enough for my application?
Re: GPIO as CS for SPI
I think it should be fine. I also think that would be a useful feature to add to the SPI driver (ability to specify a GPIO pin as a CS).
You may need to not use the builtin CS at all (or configure it as a GPIO) since the current SPI driver probably asserts it all the time.
In the meantime, you could just do it manually.

I've used GPIO for SPI-CS with good results, nothing unforseen happened.

Thank you gentlemen, that's what I was hoping for
