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。
