Dear Adafruit,

I'm implementing a new display driver with a ILI9341 controller. The new display did not work after power-on, because the reset signal is not generated correctly.
The ILI9341 datasheet describes: tRT (reset cancel) delay must be at least 5ms before sending commands. Adding a delay(5) solved the problem. This fix is applicable to all displays.

It would be great if you can merge this change. I've also upgraded all .pde projects to .ino. (minor issue)

Best regards,
Erwin

According to the ILI9341 datasheet, a delay of at least 5ms is required after releasing the RESET signal before sending commands. Some displays won't start after power-on without this delay.
