简介
这是一款2.8英寸的TFT电阻式触摸显示屏。该模块分辨率为320x240,驱动IC为ILI9341,采用SPI(4线)通信方式。板载触摸芯片XPT2046,触控芯片将AD采集的触摸数据转换成SPI数据。模块集成SD卡槽,可以轻松的从SD卡中读取全彩色位图。模块为用户提供了两种接线方式,一种为普通排针接线方式;另一种为GDI(General Display interface)接口,需有GDI接口的主控相匹配(如FireBeetle-M0),只需一根fpc线,就可即插即用,降低了接线的复杂程度。
2.8"LCD显示模块具有显示效果好、触摸灵敏、接线方便、通用性强等优点,可用于许多应用中:传感器监控和报警、Arduino温度监控器/风扇控制器、Touch界面等。

使用教程
该产品是Breakout模块,采用SPI通信方式,板载GDI接口,降低了接线的复杂程度,并且可以轻松地显示从SD卡中读取到的内容
注意:
1.GDI接口的使用需要与具有GDI接口的主控相匹配
2.建议使用Arduino1.8.10及以上版本
3.SD卡插槽接触不良,有可能会初始化失败,插拔后成功

注:由于Arduino UNO的内存容量有限,无法运行涉及UI的程序。因此,我们建议使用内存更充足的ESP32进行此类操作。
