TFT Graphics Test

The TFT FeatherWing is basically a combination of our 2.4" TFT Breakout with the STMPE610 resistive touch-screen breakout attached.

Install Libraries

You'll need a few libraries to use this FeatherWing!

Install Adafruit ILI9341 TFT Library

We have example code ready to go for use with these TFTs.

From within the Arduino IDE, open up the Library Manager...

Search for ILI9341 and install the Adafruit ILI9341 library that pops up!

Next up, search for Adafruit GFX and locate the core library. A lot of libraries may pop up because we reference it in the description so just make sure you see Adafruit GFX Library in bold at the top.

Install it!

Repeat the search and install steps for the Adafruit_ImageReader and Adafruit_ZeroDMA libraries. That’s four libraries in total.

For more details about this process, we have a tutorial introducing Arduino library concepts and installation.

Basic Graphics Test

After installing these libraries, you should see a new example folder called Adafruit_ILI9341 and inside, an example called graphicstest_featherwing.

Upload that sketch to your Feather. You should see a collection of graphical tests draw out on the TFT.

If you're having difficulties, check the serial console.The first thing the sketch does is read the driver configuration from the TFT, you should see the same numbers as below. That will help you determine if the TFT is found, if not, check your Feather soldering!

Once you've got the demo working, check out the detailed documentation over at http://learn.adafruit.com/adafruit-gfx-graphics-library for more information on how to use the GFX library to draw whatever you like!
