您可以在“示例”→“液晶”→“ HelloWorld”下的“文件”菜单上找到这个示例文件。如下图所示: 本示例使用与我们使用的引脚不同的引脚,因此请找到以下代码行: LiquidCrystal lcd(12, 11, 5, 4, 3, 2); 根据你实际的硬件连接并将其改为: LiquidCrystal lcd(7, 8, 9, 10, 11, 12); 将代码上传到您的...
标头库,然后在我们的代码中将LCDHEIGHT更改为64。 -现在要在NodeMCU上运行相同的代码,我们需要在代码中再更改一行。 “ #define OLED_RESET 4”》“ #define OLED_RESET LED_BUILTIN”其余部分代码与Arduino 差不多,显示所有我们首先需要使用 display.clearDisplay()清除上一个屏幕的内容。//清除缓冲区 然后绘制对...
Demonstrates the use a 16x2 LCD display. The LiquidCrystal library works with all LCD displays that are compatible with the Hitachi HD44780 driver. There are many of them out there, and you can usually tell them by the 16-pin interface. This sketch prints "Hello World!" to the LCD and ...

练习使用HD44780 相容的文字型LCD(Liquid crystal display),在2×16 LCD 上显示”Hello World” 讯息。 2×16 LCD 简介 HD44780 相容的2×16 LCD 可以显示两行讯息,每行16 个字元,它可以显示英文字母、希腊字母、标点符号以及数学符号,除了显示讯息外,它还有其它功能,包括讯息卷动(往左和往右卷动)、显示...

1. Buffer the Arduino LCD Display One approach I see many people try with a character LCD is letting their code directly print to the display. Using a simple buffer might look like it adds unnecessary complexity. One positive point is that you get a more predictable behavior. A trade-off ...
OLED是英文Organic Light Emitting Display(有机发光显示器)的简称,它的发光原理是指有机半导体材料和发光材料在电场驱动下,通过载流子注入和复合导致发光。通过搭配不同的有机材料,就可以发出不同颜色的光,来达到彩显示器的要求。也有人把OLED拼写为 Organic Light Emitting Diode (有机发光二极管),两种写法意思基本...
