We suggest using a [http://mchobby.be/PrestaShop/product.php?id_product=12 protoshield] (with stacking headers) or a proto-screwshield to access the unused pins (2, 3, and analog 4 and 5). You can connect various i2c sensors or analog sensors to analog 4&5. You can also connect an i2c port expander to get more I/O pins. If you desperately need more pins, and you're careful, you can use the 8 datapins while the TFT isn't being written to - they are high-z and unused as long as the WR and RD pins are high

== Démarrer sans assemblage ==
Ce shield est vraiment facile à utiliser. Il n'y a qu'a le raccorder et c'est parti.

Because the TFT is exactly the same size as an Arduino, we preassemble the shield in the factory. To use, simply place it onto your Arduino. No wiring, no soldering!

== Test du LCD ==
We have a library with example code ready to go for use with these TFTs. The library is not incredibly fast and optimized but its a good start and can easily be ported to other micrcontrollers. However, we'll assume you're using an Arduino
[https://github.com/adafruit/TFTLCD-Library Visit our github repository] and click on the Downloads button in the top right corner to download a zip of the library and examples. Uncompress the folder and rename it TFTLCD make sure that inside that folder is the cpp and .h files. Then copy it to your arduinosketchfolder/libraries folder.
