It can be used as display device or sketch pad.Compared with the previous version, 2.8’’TFT Touch Shield V1.0 , we replaced the screen driver with a more professional chip, ILI9341 driver, providing different pin-saving SPI communication without sacrificing the data transmitting speed. Due to the communication method change, programs developed for the original version need modifications before being transplanted to the new version. With a SD card module integrated also on this shield, this shield reserves great room for other expansions to your project. 9 | 10 | 11 | **Features** 12 | 13 | - Big screen for easy and comfortable experience 14 | - Backlight controllable via programming 15 | - 65535 rich colors display 16 | - SPI pin-saving communication method 17 | - Full screen touch active range 18 | 19 | 20 | 21 | ##Usage 22 | 23 | This is a driver library for Tft Touch Shield. 24 | 25 | For more information, please refer to [wiki](http://www.seeedstudio.com/wiki/2.8%27%27_TFT_Touch_Shield_v2.0). 26 | 27 | 28 | ---- 29 | 30 | 31 | This software is written by loovee [luweicong@seeedstudio.com](luweicong@seeedstudio.com "luweicong@seeedstudio.com") for seeed studio
