Video Tutorial After the Break…
Updated to Adafruits Lastest GFX LIB’s also includes them….3/10/2013
This Screen tho not large in size is quite spectacular in Ability and Ease of use because of Adafruits extensive Libraries for it.
If your here to learn some of the basics of working with this wonderful LCD. THAT’S FANTASTIC!! Please feel free to request any additional Tutorial Ideas as I’m planning to cover this Screen with a little more depth on next video Segment.
If however You don’t own one, Maybe your just trying to decide Which Lcd is right for you well.. look no further. Your not going to find a LCD that works great with an arduino with a larger fan base and plenty of helpful people to answer your questions.
You can get one of these LCD’s through Adafruit from HERE…..
Be sure to check MANY Other of there great items as there’s many.
Adafruit has a Plentiful Forum located HERE…. Where they Cover this and many other products, projects and coding.

For a pinout an Wire up guide for the breakout version. Adafruit has a great walk through HERE………

You Can Download Sketch Code: For Break Out Board LCD Here…….
You Can Download Sketch Code: For Shield Coming Soon….
Lastly If you have any questions, comments, or suggestion be sure to ask them…
Sobiguy…
Thanks for your code. I just received my touch shield and was looking for ‘buttons’ for my current project. I have been looking on the net for an example of how to create a graph using numbers from an array. Can you point me in the right direction? I have an Uno.
Thanks,
Eric
Hey Eric,
What kinda of graph are you talking about. Or are you referring to drawing a bmp from an array.
Sobyguy..
I have an array with 300 places in it.(Not sure of the proper way of saying that) The data is from a load cell. I would like to make a simple graph showing the index number (1 to 300) across the x axis and the data within the index location in the y position. If I plot the data as mentioned I’m looking to get a nice smooth sine wave. I have created a grid for my touch panel, I’m just not sure of how to create a sketch to plot the numbers in the array onto the graph. Id just like to get pointed in the right direction of getting this to work on my tft panel. Id also like to create a graph in Processing down the road that I can see on a PC and/or Iphone.
Thanks,
Eric
Looks like your attempting something between an arduino like oscilloscope and and table/arrays.
See if any of these link help you in the right direction…
Explains getting useful info from table/arrays= http://arduiniana.org/libraries/flash/
tho not for arduino process would be similar= http://en.flossmanuals.net/pure-data/ch045_arrays-graphs-tables/
I would say you could put in your table into code then
write a function the goes through your table index 0-300
int data = 300;
for (int i = 0; i < data; i++)
Use “I” as a X value
then use above also for y value but change it postion over time (millisec)
Hope this atleast helps.
[...] SobiGuy over at sobisource.com has put together a great 10 minute video tutorial on interfacing the Adafruit 2.8″ TFT LCD with touchscreen breakout board. Here is what he has to say about the LCD: This Screen though not large in size it is quite spectacular in ability and ease of use because of Adafruit’s extensive libraries for it. [...]
Hi i have this same display in the breakout board and i’ve followed the tutorial given by adafruit but still cant seem to get it to show anything.
I double check the wiring and used the code given but it still does not work. Is there anything i cud try?
What arduino are you using. Is the screen backlight at least turning on? If the screen is not at least turning on when you power the arduino check your positiveand ground connections first. If your backlight is turning on let me know on we’ll move on.
By no reply? I’m guessing that fixed your problem?
Hello. Thjis looks great but something goes wrong from the library, the only one i found is Adafruit_TFTLCD not TFTLCD. Modifying the code or the library always leads to the same errors as the Adafruit_TFTLCD library seems not to contain the neccessary code to make it work.
Coulkd you help me to find the TFTLCD library you used for this project ?
Thanks for your help.
Hey francis,
Sorry for the long reply,
Adafruit has created an entirely new library which breaks pretty much everything i have ever wrote for the TFTLCD. How ever you are in luck SIR. I did have a backup of the original libs
HERE: http://sobisource.com/files/tfttouch_tftlcd.zip
Those should get you going. I’m currently Upgrading all my old programs for both IDE 1.0+ and adafruits new GFX Libraries. These will be up very soon…..
SobiGuy
I have been working hard on rewriting all my programs for the new GFX libs. And this one along with a new video is up next. expect updates this weekend. Or follow me on twitter to be notified the moment it released….
Sobiguy
Hello, Everyone!!! Latest Release is out for the break out board!!!!!!
The Shield version is next and a new video explaining the changes will be following soon!!!
Enjoy
