/*
Esplora TFT Temperature Display
This example for the Arduino TFT screen is for use
with an Arduino Esplora.
This example reads the temperature of the Esplora's
on board thermisistor and displays it on an attached
LCD screen, updating every second.
This example code is in the public domain.

// include the necessary libraries
#include <Esplora.h>
#include <TFT.h> // Arduino LCD library
#include <SPI.h>
char tempPrintout[3]; // array to hold the temperature data
void setup() {
// Put this line at the beginning of every sketch that uses the GLCD
EsploraTFT.begin();
// clear the screen with a black background
EsploraTFT.background(0,0,0);
// set the text color to magenta
EsploraTFT.stroke(200,20,180);
// set the text to size 2
EsploraTFT.setTextSize(2);
// start the text at the top left of the screen
// this text is going to remain static
EsploraTFT.text("Degrees in C :\n ",0,0);
// set the text in the loop to size 5
EsploraTFT.setTextSize(5);
}
void loop() {
// read the temperature in Celcius and store it in a String
String temperature = String(Esplora.readTemperature(DEGREES_C));
// convert the string to a char array
temperature.toCharArray(tempPrintout, 3);
// set the text color to white
EsploraTFT.stroke(255,255,255);
// print the temperature one line below the static text
EsploraTFT.text(tempPrintout, 0, 30);
delay(1000);
// erase the text for the next loop
EsploraTFT.stroke(0,0,0);
