RST is optional

[seth10]

From what I can tell the RST parameter does not have a default argument. If we opt to not use it, what value should we pass when constructing?

any other pin, and connect it to the arduino RESET

Here is an excerpt from the graphicstest example:

// These are the pins used for the UNO
// for Due/Mega/Leonardo use the hardware SPI pins (which are different)
#define _sclk 13
#define _miso 12
#define _mosi 11
#define _cs 10
#define _dc 9
#define _rst 8

// Using software SPI is really not suggested, its incredibly slow
//Adafruit_ILI9340 tft = Adafruit_ILI9340(_cs, _dc, _mosi, _sclk, _rst, _miso);
// Use hardware SPI
Adafruit_ILI9340 tft = Adafruit_ILI9340(_cs, _dc, _rst);

Here _rst is defined as 8. I do not have a pin number for reset, only the first two (_cs,_dc). What should I pass as the third argument to the Adafruit_ILI9340 contructor?

some disconnected pin. that's the only thing supported right now.

@ladyada Okay, thank you!
