At Gregory Brettin's request, I am looking into developing a stand alone 7" LCD screen for his custom "fibreglass cubby screen holder" (my words, not his!)

Driving a large 7" display with a microcontroller is a little challenging.
In order to get 30 frames per second for a smooth display, it requires a data rate of 5.76 million bytes per second (@ 4 bits/colour)

Yes, you could use a Raspberry Pi, but I *hate* the 20-30 second boot up EVERY TIME you start your car.

A microcontroller start up is less than 1 second when you have a 1 second splash screen. (Meaning it is almost an instant start up)

Development of the 7" gauge display will start in the new year.
