Share My Creation Experimenting with an Arduino and a ST7735R TFT Display

Hi guys,

@Erel asked for a picture of my display after having so promptly created a Library for my TFT 1.8" ST7735R display.

So after a few successful tests, I decided to create something worthy of EREL's eyes.

So here I give you a small video of what can be achieved in a very few lines of code, if you put aside the C code block.

The source code for this image is attached

Small Update:
InitializeSoftware vs initializeHardware

Using InitializeSoftware is the more versatile schematics wise, as it allows any pins to be used, but it has a downside... its a slow refresh rate!
Using InitializeHardware forces the chematics to use the SPI pins (basically you use pins from 8 to 13, except pin 12, IF you don't use the built in SD card reader, BUT, it's about 2 to 3 times faster!
