Thinking of using an Arduino or set or Arduinos to build a Flight Simulator Cockpit.

Would it be possible to have multiple TFT displays  says the 2" or 5"   Non touch displays
from a single Arduino  (e.g. Mega 2560) ?

Or is it going to take one Arduino per screen ?

For reference the Air displays in the top right corner ?

depends on the interface of the TFT and the amount of data updates.

My gut feeling says one Arduino per screen makes sense.

While it probably feasible, being perhaps merely a matter of sorting out the chip select, you probably won't contemplate the distribution boards and cabling for too long before you decide it isn't a good idea.

The other problem is the speed. No matter how you go about it, you need to check what has gone before to ensure that a Mega is up to this sort of job. It is already clear that the joys of using a larger display come with a noticeable speed hit, and having multiple screens will probably make a bad situation worse.

My requirements are much more humble than anything you have in mind, but I suspect it may turn out that switching to a large LCD is not a proposition.

You are going to run out of Pins .. One display takes a lot, you could multiplex many to multiple displays but some will need to be unique..

Suggest one Mega per display with cmmunication between..

Hum... Does Chip Select ring a bell?
