To enable the display in 8-bit mode, only the row of pins along the narrow edge is used. It's a clone of the more common HY-TFT240, and it has two rows of pins, set at right angles to one another.

Note that the 8-pin connector is not used. The hardware connections: On 11-pin connector. Note that due to the memory requirement of UTFT, this display will work with a standard UNO only with extensive tweaking - it would be necessary to delete pretty much all the graphics in the sketch, and just stay with text. It uses Henning Karlsen's UTFT library, and it does a fine job with text and graphics. These can be obtained for just a few bucks on eBay and elsewhere, for example - $3.56 delivered from China. It is 5-volt friendly, since there is a 74HC450 IC on the circuit board that functions as a level shifter. This one is a 1.44" display with a resolution of 128 x 128 pixels, and it uses an ITDB18SP driver. Lead cutting shears (Plato makes good ones).A good multitester and/or continuity tester.Purple, blue, and green ones are suspect - see picture and. These typically take only a 200 mA charge, and even an "intelligent" charger will not refresh them. Note: Beware of cheap ripoff batteries from Hong Kong. A couple of sets (4 each) of decent rechargeable NIMH AA batteries.Battery-powered soldering iron (the Hakko FX-901 is best of breed).Arduino Uno or Hackduino - wired for 3.3v operation, otherwise you'll need to mess with level shifters.Female headers (these come in strips of 40).One or more unpopulated protoshields, both for Uno and Mega/Due.A solderless breadboard male-to-male jumpers male-to-female jumpers 22 gauge insulated hookup wire, solid Graph paper, for planning and sketching wiring diagrams and layouts.Finally, interface the display to your favorite Arduino project and write a sketch that adds colorful text and graphics to it.Īn assortment of cheap TFT LCDs ($20 ought to get you three or four)īefore you buy, check for Arduino compatibility!.With the display functional, you can then hack together a breakout board or plug-in shield.With luck, you will see text and/or graphics. Load an example sketch into the Arduino IDE, and then upload it to the attached Arduino board with wired-up TFT display.

Figure out how to hook up the hardware, i.e., which display pins are wired to which pins of the Arduino.

On a Linux machine, as root, copy the library archive file to the /usr/share/arduino/libraries directory and untar or unzip it.

Download and install the driver library.

Henning Karlsen's UTFT library works with many displays.

Find out whether there is an Arduino driver available.

Determine the display's resolution and the driver chip. Otherwise, it may involve matching its appearance with a picture on Google images. With luck, it will have identifying information printed on it. But, how is it possible to determine which ones will work with an Arduino? And what then? Here is the procedure: There are quite a number of small cheap TFT displays available on eBay and elsewhere. This makes it feasible to reuse them to give our electronic projects colorful graphic displays. These have been manufactured in the tens of millions for cell phones and other gadgets and devices, and that is the reason they are so cheap now. Moreover, it can display not just text, but elaborate graphics. For as low as $4 (shipping included!), it's possible to buy a small, sharp TFT screen that can be interfaced with an Arduino. No! For about the price of a familiar 2x16 LCD, you get a high resolution TFT display. You say you want to hook up a TFT display to an Arduino? Are you joking?
