This Arduino shield contains a 16bit colour TFT screen with a 2.4" display and is designed to fit directly into the standard headers of an Arduino Uno requiring no additional interface hardware. The shield includes level shifters to safely interface to your 5V Arduino. Additionally there is also a built in micro SD card reader allowing you to store data such a graphics and icons to be displayed directly on the screen saving much needed memory. On top of all this we have also created our own library (HCTFT) to make it as easy as possible to use this display with an Uno. The library can be downloaded from our support forum.

PLEASE NOTE: This display is not fitted with a touch controller. Available pins when fitted to an Uno: D0, D1, A5. Additionally if SD card not required pins D10,11,12 & 13 are also available.

Example Arduino Sketch Using HCTFT Library:

Code: Select all

/* FILE:    HCTFT_Example_1_Random_Graphics
   DATE:    17/06/15
   VERSION: 0.1
   AUTHOR:  Andrew Davies

   
This example will output graphics, text and bitmap data randomly to the screen.
The sketch demonstrates the use of these vairous functions including how to
set their colours and positions on the screen.

To use this sketch you will need to uncomment the appropriate initialisers below
for your particular display.

IF YOU GET AN OUT OF MEMRY COMPILE ERROR:
Library support for TFT screens can be quite memory intensive. If you are using 
an UNO you may find that you will get and out of memory compile error. To get the
sketch to compile you will need to edit the MemorySave.h file in the HCTFT folder
to free up some memory.
