Dan East / Adafruit_ST7735

A first port of the excellent Adafruit ST7735 library Also supports the S6D02A1 controller (Use 1k resistors in series on all logic lines).

Fork of Adafruit_ST7735 by Andrew Lindsay

Modified version of the ST7735 library to support the Samsung S6D02A1 controller. These 1.8" 128x160 displays can be purchased dirt cheap (under $5 on eBay or aliexpress with free shipping).

You must also import the Adafruit_GFX library, as this library is dependent upon it.

I've used up to 20 MHz SPI with no problem. That is hardcoded in the library, and is currently set to 4 MHz (unmodified from the original library).

The library is exactly the same for S6D02A1 and ST7735 except for the initialization routines.

Use 1k resistors in series on all 5 logic lines as 3V3 is required (display is not damaged by 5V logic, but it will not work)

Constructor pin names that match the S6D02A1: Adafruit_ST7735(DIN, NC, CLK, CD, D/C, RST) ;
