Most of the available TFT displays have a SD Card slot on the back, the connections to this are usually separate to the display interface so must be wired up. This instructable will tell you how to wire an Arduino UNO to a 2. These displays are available at low cost on eBay. Connections are different to those in my other Instructables this is for my convenience!

Other pin outs at the Arduino can be used by adapting the sketch should you have a display from another supplier or wish to use an existing setup. The SD card might survive such abuse but you may not be lucky Ideally we would use a logic level converter but resistors are so cheap and they work fine at these frequencies because the stray capacitance of the lines we are driving is not that significant. The display is quite greedy on power so the dissipation in the resistors is not that significant in comparison.

Do not insert and remove the SD card when the Arduino is powered, this can does! 320x240 bmp images will need the libraries in the attached zip file and the SdFat library included for convenience. The standard SD library can be used but this requires minor changes to the sketch and will run slower.

The main changes to the ILI library are to enhance speed and to add the pushColors function, one to handle integer arrays for BMP drawing and one for byte arrays raw images. In the zip file you will find a folder 320x240 bmp images images, put these on a 320x240 bmp images formatted SD card for the Arduino to read not in a directory!

You can modify the SD library examples to use the above pins to check a sketch can access the files and the wiring is good. If in trouble post a plea for help I may have made a mistake or may be able to help you get your setup going, bear in mind that it is difficult to debug major problems by exchanging a few messages Most of the image files are in BMP format, so it is left as an exercise to convert them to raw format, amend the sketch and see the improved drawing speed.

I use the compiler -O2 option as in my Instructable here. The standard -Os 320x240 bmp images will make smaller code images but it runs slower when IDE 1. IDE 1. The image drawing function is part of the sketch not the library, this is deliberate as it is all too easy to create a heavyweight memory hungry feature rich library that puts a strain on the AVR based Arduino's capability!

Well that's my excuse ;- Some folk solve this by making a simple wrapper library that contains these functions and calls lower level libraries, so this is an option for the future.

The file name must be in the 8. See the last Step of this Instructable for the function of the flip flag. The width and height of the image are extracted from the BMP file. As there is just pixel who views your facebook profile s in this file the width and height of the image must be 320x240 bmp images to the function. If someone does get the sketch running on a DUE I would be interested to here how it performs, if the SPI can be run at 48MHz then an entire screen update could probably be performed in less than ms To run the SPI at this frequency you would probably need a digital logic level converters.

If you add your own images make sure they are 24 bit color BMP files and they have a width and height compatible with the display. In Windows the free Paint software can be used to crop, resize, flip and save images in 24bit BMP format. There is little error checking in the code, so images can be corrupted by drawing off the screen edge and may not get drawn at all if the file cannot be found or format is wrong etc, but the Arduino should keep going and I have not had a crash yet.

I have removed all debugging print statements to reduce the code size, but Serial is called up in setup. Paint can also be used to pick colours off images to see the 24 bit RGB value, these can be converted using a calculator or a library function to the 16 bit format used for the display. Raw image files are quicker to draw and can be created straight from the BMP file using a utility called "ImageConverter Use the ".

The pixel ordering means they draw top down too, this image converter is a great little utility that saves me writing a sketch for the UNO to seek BMP files and convert them I might do that anyway! The common BMP format is to store 320x240 bmp images image in raster fashion from the 320x240 bmp images upwards but the graphics and plot windowing expects an image to be drawn top down.

Manipulating file pointers to draw top to bottom slows down image rendering significantly, so the drawing routine and library uses the hardware TFT SGRAM rotation feature, this means we can quickly draw from 320x240 bmp images to top.

After plotting the image the display is returned to the normal top left is 0,0 orientation. This has been done in sympathy with the capabilities of the UNO by sacrificing a neater but bigger and slower software darthmod 5.5 and style for a significant performance advantage!

The price to pay is a couple of mouse clicks when preparing the image just flip vertically before saving in Paint. The displayed images are nice and crisp with vibrant colours, so the screen shots made with my webcam don't do it full justice. The raw bitmap 320x240 bmp images are more representative of what you will see on the display.

320x240 bmp images GFX functions line drawing, text, etc. Again Paint 320x240 bmp images be used to help work out the 320x240 bmp images when plotting over 320x240 bmp images.

It is surprising how quickly the humble UNO can plot SD Card images to the screen when the code loops are kept short and sweet. In fact this library and sketch can fetch an image from the SD Card and draw it on screen in less time than some graphics libraries take to just clear the screen The library and sketch has been test on the new 1.

I use optimisation level as in my Instructable here. These libraries are highly optimised version of libraries created by others hence the Adafruit label.

All graphics drawing functions are still their under the bonnet "hood" for readers in the USA. The line drawing algorithm has been optimised and se 208ab lightscribe much faster than the basic Bressenham method because it uses the fact that short multi-pixel horizontal 320x240 bmp images vertical line segments can be drawn much more quickly that individual pixels.

The further the 320x240 bmp images away from 45 degrees no multipixel line segments the faster a line will draw. An example modified UTFT graphics test sketch is included to show the impressive speed improvement: Thank you for reading my Instructables, it has been 320x240 bmp images to get such positive feedback.

The message reporting service on Instructables seems to be a little unreliable for some reason, so sometimes I do not see new posts, bear this in mind! It could unintentionally be the case that the libraries are no longer compatible with Adafruit products, so bear this in mind and do NOT contact Adafruit if 320x240 bmp images have a problem!

As the changes made are now quite significant it is the intent to rename this library in future whilst keeping the acknowledgement to Adafruit within. If this change does happen then I will create an associated Instructable.

The table shows how significant the performance improvements are, these improvements are a result of adapting the software to the capabilities of the processor and displays. There are no plans to migrate the Library to ARM processors DUE etc as I do not have the need, the projects I have planned only need to update the display infrequently every few seconds as the parameters being monitored do not change quickly and by writing the software efficiently to only update the areas of the screen that change means I can get flicker free updates.

The result for the 5. Essentially making use of the fact that short horizontal and vertical line segments are in the lines apart from one case at 45 degreesthese segments can be drawn much more quickly than plotting individual pixels.

Uncomment the line:. Run Length Encoding One of my next graphics projects will use icons, these are simple images such as thermometers, compass dials etc that generally 320x240 bmp images few colours with relatively large areas 320x240 bmp images the same colour, this makes them suitable for compression with a Run Length Encoding RLE algorithm. This will make pulling them off the SD card and plotting them even faster as the typically the RLE compressed files will be significantly smaller than a raw bit map.

As an example a raw image of 60 x 60 pixel icon is bytes, RLE of a simple graphic of a warning triangle could be only bytes. Watch this space " "!

HelloI have a problem with this sentence if! Thank you and great work. Reply 4 weeks ago. The sketch uses the SdFat library. Make sure this SdFat library is loaded and the examples run. I would mount it on an Arduino Mega and recall 320x240 bmp images images uploaded to SD with a button Reply 2 years ago. It's kind of working to my surprise, but only the colours and the screen alignment are not correct. Anyway, thanks again for your great work!! Reply 3 years ago. Thanks for the reply! I used the schematic and pin described in this instructables, 1.

OK, some SD Cards like fast transitions between logic levels. Try Ohms and 1K instead of 1K2 and 1K8. Check your display does not already have 1K in line resistors connected to the SD Card, or post a picture of the back of the display board so I can have a look for you. Reply 320x240 bmp images years ago on Introduction. Good news! I have tried various 320x240 bmp images methods and found that the basic run length encoding is a good compromise between reducing the font files and making the rendering of fonts 320x240 bmp images screen faster.

At the moment I have the adapted graphics libraries running with a x display with the HX driver. I can adapt other driver libraries, if you wish to try the new encoded font files then let me know which TFT driver chip you are using, then I can create a low down dirty shame soundtrack mp3 for you to try out. Great, excited to hear it.

320x240 bmp images, as you found, a sweet spot with the TFTs in terms of price is those ili 2. The touch chips work with uTouch library apparently, i started on the touchless ones, 320x240 bmp images my touch version have arrived now. I should try one of those, look like great value. In cheap x, if you didn't see ityou might want to check out the HXA one, http: Another interesting one: I ordered one. I like smooth big fonts.

In this case even moving to a dedicated p was not enough, I found I wanted to buffer a lot of stuff in ram for the data logging and graph, and sd bitmaps were out of the question, and drawing could always be faster, so I moved again 320x240 bmp images the stm32f1.

I still want to use p with the Ili where ideal. Having compressed fonts, and flash chips, makes that SO much more possible.
