Multiple SPI devices WiPy 3.0
On my project I want to use TFT, SD adapter and camera using SPI. I've seen something about Slave Select, but I'm not sure how to properly connect and use it on breadboard.
Have someone done it before? Only one external device will be used at same time.

@EngeenerAtendee Each device should have a CS input, which must be pulled low to activate it. You can share SCLK, MOSI and MISO for all three devices, and have to pull CS low for the one that is to be used. So you need 6 GPIO ports.
