// IMPORTANT: LCDWIKI_SPI LIBRARY AND LCDWIKI_TOUCH LIBRARY MUST BE SPECIFICALLY
// CONFIGURED FOR EITHER THE TFT SHIELD OR THE BREAKOUT BOARD.

//This program is a demo of display phonecall UI

//when using the BREAKOUT BOARD only and using these hardware spi lines to the LCD,
//the SDA pin and SCK pin is defined by the system and can't be modified.
//if you don't need to control the LED pin,you can set it to 3.3V and set the pin definition to -1.
//other pins can be defined by youself,for example
//pin usage as follow:
//                  CS  DC/RS  RESET  SDI/MOSI  SDO/MISO  SCK  LED    VCC     GND    
//Arduino Mega2560  A5   A3     A4      51        50      52   A0   5V/3.3V   GND
//                 T_IRQ  T_DO  T_DIN  T_CS  T_CLK
//Arduino Mega2560  49     47    48     45    46

//Remember to set the pins to suit your display module!
