Browse source 
* Add files via upload

* Add files via upload

* Update SPI.h

* Update esp32-hal-spi.c

renamed invert_out to ss_invert to be more intuitive

* Update esp32-hal-spi.h

Removed the out from the function name spiSSInvertout.

* Update SPI.cpp

Removed the out from the function name spiSSInvertout.

* Update cores/esp32/esp32-hal-spi.c
