7" tft display - multiplexing and smallest arduino that can be used

Other Hardware Displays

Hey Frienduinos,

I have a few questions regarding 7" tft touch displays and would appreciate any insight regarding them

  1. Can i use multiplexers to reduce the number of pins that a 7" tft touch display generally uses? Would this slow performance significantly? I need to save pins on the mega2560 for sensors and a serial touch display is a bit too expensive for me

  2. Whats the smallest arduino that can be used effectively communicate with the 7" tft touch display

Thank you all for your help. I hope these questions help anyone else out there with similar thoughts
