17.2 硬件设计1. 例程功能使用开发板的WIRELESS接口连接正点原子SPILCD模块(仅限SPI显示模块)，实现SPILCD模块的显示。通过把LCD模块插入底板上的WIRELESS接口，按下复位之后，就可以看到SPILCD模块首先进行纯色刷屏测试，后面就显示LCD例程实验信息以及显示正点原子Logo以及一个3D立方体。2. 硬件资源1）

Arduino TFT_eSPI库来驱动SPI接口的LCD显示详解 相关库github地址:https:///Bodmer/TFT_eSPI 文字显示过程详解 TFT eSPI显示文字的方式比较有意思,通过创建一个画布,然后将文字在画布中显示,最后将画布推送到屏幕的指定位置,具体步骤如下: 导入相关函数,并创建实例. ...
我们必须指定诺基亚LCD 5110显示器连接到的引脚。显示器使用SPI通信进行通信,如果您遵循了上面的电路图,则初始化LCD的代码将如下所示,您无需更改它。 Adafruit_PCD8544 display = Adafruit_PCD8544(7, 6, 5, 4, 3); //Specifiy thepins to which the LCD is connected ...
由于SPI有特殊的硬件支持,以上四个引脚必须正确连接到指定位置,此外还有几个引脚需要连接: VCC&GND:电源 LED:背光灯的控制信号 RST:屏幕复位信号 从文档中就可以找到我们屏幕的引脚定义了: LCD液晶屏的引脚定义 再看ESP8266这边的引脚图: ESP8266-NodeMCU开发板引脚图 ...
