An example analogue clock using a TFT LCD screen to show the time
use of some of the drawing commands with the ST7735 library.
For a more accurate clock, it would be better to use the RTClib library.
But this is just a demo.
This examples uses the hardware SPI only. Non-hardware SPI
is just too slow (~8 times slower!)
Uses compile time to set the time so a reset will start with the compile time again

This sketch uses the GLCD and font 2 only. Disable other fonts to make
the sketch fit in an UNO!
This sketch uses the GLCD and font 2 only.
Make sure all the required fonts are loaded by editting the
User_Setup.h file in the TFT_eSPI library folder.
Make sure all the display driver and pin comnenctions are correct by
editting the User_Setup.h file in the TFT_eSPI library folder.
The library uses the hardware SPI pins only:
For UNO, Nano, Micro Pro ATmega328 based processors
MOSI = pin 11, SCK = pin 13
For Mega:
MOSI = pin 51, SCK = pin 52
The pins used for the TFT chip select (CS) and Data/command (DC) and Reset (RST)
signal lines to the TFT must also be defined in the library User_Setup.h file.
Sugested TFT connections for UNO and Atmega328 based boards
sclk 13 // Don't change, this is the hardware SPI SCLK line
mosi 11 // Don't change, this is the hardware SPI MOSI line
cs 10 // Chip select for TFT display
dc 9 // Data/command line
rst 7 // Reset, you could connect this to the Arduino reset pin
Suggested TFT connections for the MEGA and ATmega2560 based boards
sclk 52 // Don't change, this is the hardware SPI SCLK line
mosi 51 // Don't change, this is the hardware SPI MOSI line
cs 47 // TFT chip select line
dc 48 // TFT data/command line
rst 44 // you could alternatively connect this to the Arduino reset
Note that yield() or delay(0) must be called in long duration for/while
loops to stop the ESP8266 watchdog triggering.
