2.4" 320*240 HMI Intelligent Smart USART UART Serial TFT LCD Module Display Panel for Arduino without Touch Panel

// IMPORTANT: LCDWIKI_SPI LIBRARY MUST BE SPECIFICALLY

// CONFIGURED FOR EITHER THE TFT SHIELD OR THE BREAKOUT BOARD.

 

//This program is a demo of how to display picture and 

//how to use rotate function to display string.

 

//Set the pins to the correct ones for your development shield or breakout board.

//when using the BREAKOUT BOARD only and using these software spi lines to the LCD,

//there is no MISO pin and You can use any free pin to define the pins,for example

//pin usage as follow:

//             CS  CD  RST  MOSI  MISO  CLK  LED 

//Arduino Uno  A5  A3  A4   A2    NONE  A1   A3

//Arduino Mega A5  A3  A4   A2    NONE  A1   A3

 

//when using the BREAKOUT BOARD only and using these hardware spi lines to the LCD,

//there is no MISO pin 

//the MOSI pin and CLK pin is defined by the system and can't be modified.

//other pins can be defined by youself,for example

//pin usage as follow:

//             CS  CD  RST  MOSI  MISO  CLK  LED 

//Arduino Uno  10  9   8    11    NONE  13   A3

//Arduino Mega 10  9   8    51    NONE  52   A3

 

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