Running two SPI TFT screens with the same cable select pin?

by telarium on Wed Jun 16, 2021 7:55 pm

If I wire two SPI TFT screens (like Adafruit's 2.0" 320x240 Color IPS TFT Display) to the same pins on a Raspberry Pi, will it show the same video output on both? I'd prefer to only send the video once to two SPI screens using the same cable select pin if possible. I'm not planning on using the SD card or anything, so communication only needs to be one-way.

This is just such a case I would try. Can't kill much with it.
Never tried it on SPI screens, but with LED segment displays you can do just this, tried 6 screens on same channel.
