米思齐tft_spi模块库演示程序。心知天气、阿里云时钟、WiFi信号强度检测、1分钟滚屏、更新天气时间为15分钟、加入天气图标。更新天气次数。断网检测 。此程序为tft_eSPI图形库演示、如感觉好可以自行优化。
ili9431tft_espi库是用于ESP32和ESP8266芯片的TFT LCD驱动程序库，可用于控制ILI9341和ILI9431 TFT显示屏。以下是配置ili9431tft_espi库的步骤：
-
下载并安装Arduino IDE。
-
在Arduino IDE中，导航到“文件”>“首选项”>“附加开发板管理器网址”并输入以下网址：
https://dl.espressif.com/dl/package_esp32_index.json,http://arduino.esp8266.com/stable/package_esp8266com_index.json
-
点击“确定”按钮，关闭“首选项”窗口。
-
导航到“工具”>“开发板”>“开发板管理器”。
-
在搜索栏中输入“ESP32”或“ESP8266”，然后选择相应的开发板并安装。
-
连接ILI9341或ILI9431 TFT显示屏到ESP32或ESP8266芯片。
-
在Arduino IDE中，打开一个示例程序（例如：ILI9431test）。
-
在示例程序中，确保指定正确的引脚连接和显示屏类型：
#define TFT_DC 15
#define TFT_CS 14
#define TFT_RST -1
#define TFT_MOSI 23
#define TFT_CLK 18
#define TFT_MISO -1ESP_ILI9341 tft = ESP_ILI9341(TFT_CS, TFT_DC, TFT_RST, TFT_MOSI, TFT_CLK, TFT_MISO);
-
上传示例程序到开发板。
-
测试ILI9341或ILI9431 TFT显示屏是否能够正常工作。

如用arduino IDE需将上边库文件放到一个文件夹下即可编译。
如用mixly 米思齐编译器 上边文件必须放在这安装目录下。如：D:\Mixly1.20back\arduino\portable\sketchbook\libraries\Fonts 。Fonts这为新建文件夹名字。
