发个2.4 TFT 模块的库 希望能帮到大家
在某宝上买的价格不怎么贵大概30多吧做个菜单显示什么的还不错 自己带触摸的这是库文件 分两个 显示和触摸
大家自己改下格式吧
还不会用它显示
有大神帮忙给写个代码吧 沙发 支持！！ 怎么用这个库能说明一下么？

具体也没怎么试过 这是在网上查到的一段代码选择颜色 并且写字#include "TFTLCD.h"
#include "TouchScreen.h"

} 请问你实验过了吗？
这个触摸屏要占用几个pin？
看代码，需要占用5个。
TFTLCD tft(LCD_CS, LCD_CD, LCD_WR, LCD_RD, LCD_RESET);

我试过了UNO的模拟 数字口基本全部占了主要是他带了SD查扣占了几个触摸屏貌似是四个 TFT的主控芯片是哪个？不然怎么使用呢？ 表示有一个更强大的TFT库:utft度娘一下即可! 表示有一个更强大的TFT库:utft带触摸:utouch
度娘一下即可! 貌似不知道主控芯片，没法用啊！ 也有这个屏，哪位大虾能给个程序啊 貌似用的pin有点多 有结果了么 tft上显示用传感器显示汉字真坑爹，R3的内存都不够 继续求这个屏使用
