Forum Post: GPIO as SPI Chip Select

Hi,

I am struggling to find information about using GPIO pin as chip select for SPI bus 2.

I chip_select is a GPIO pin and I am not sure how I can do that. Its own pins are used for other devices but I have to use this bus for IO Extender whose chip select is connected to processor GPIO pin but others are wired direct to McSPI2

Any help in this would be great.

Thanks

Ali
