加载完成后，打开arduino libraries 目录（如果忘了，查看ide首选参数里找）TFT_eSPI目录下 修改一下几次配置（我的TFT芯片是ST7735所有使用这个）：// Tell the library to use 8 bit parallel mode (otherwise SPI is assumed)//#define TFT_PARALLEL_8_BIT// Display type - only define if RPi display//...
TFT LCD 与 Arduino 连接: 2.4英寸TFT LCD屏幕是一个完美的Arduino Shield。您可以直接将LCD屏幕推到Arduino Uno的顶部,它将与引脚完美匹配并滑入。但是,出于安全考虑,用小绝缘胶带覆盖Arduino UNO的编程端子,以防终端与TFT LCD屏幕接触。在UNO上组装的LCD如下所示。 为TFT LCD 编程您的 Arduino: 我们正在使用SPF...

使用Arduino IDE新建一个项目,并编写代码。 示例代码如下: 该代码利用图形库绘制了一些线条和图案,这一讲主要先测试一下LCD驱动,下一讲我会介绍图片的显示。 #include<SPI.h>#include<TFT_eSPI.h>#include<Adafruit_GFX.h>floatp=3.1415926;// TFT_eSPI tft = TFT_eSPI(240, 240);TFT_eSPI tft=TFT_eSPI...
