Adapted example For TTGO TS V1.2 | |
I made a view changes | |
set to 1.4" | |
adapted the mediabuttons - the button now fit to the 1.4" screen | |

This is a library for the Adafruit 1.8" SPI display. | |
This library works with the Adafruit 1.8" TFT Breakout w/SD card | |
----> http://www.adafruit.com/products/358 | |
The 1.8" TFT shield | |
----> https://www.adafruit.com/product/802 | |
The 1.44" TFT breakout | |
----> https://www.adafruit.com/product/2088 | |
as well as Adafruit raw 1.8" TFT display | |
----> http://www.adafruit.com/products/618 | |
Check out the links above for our tutorials and wiring diagrams | |
These displays use SPI to communicate, 4 or 5 pins are required to | |
interface (RST is optional) | |
