▼执行PixelToMatrix.exe就可开始绘制图型,绘制完成后点击「Generate」,将会自动产生16 进位或 2 进位的代码,您可将此代码加入您的程式中,如上面范例第16行「爱心-1」。 程序十二:随机生成的一个 LED 模拟弹跳点 Arduino参考开源代码 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 2...
将8个LED发光二极管封装在一起就组成了数码管,将更多的LED组合在一起就组成了点阵屏。本篇我们来认识点阵屏,通过Arduino的IO口直接驱动点阵屏来了解其驱动方式。 一.点阵屏介绍 LED点阵屏由LED发光二极管组成,通过控制LED亮灭来显示文字、图片、动画、视频等,被广泛应用于公共场合做信息展示,如广告屏、公告牌等。
基于Arduino的Dot matrix有各种各样的库。Ledcontrol和MaxMatrix库是两个最常见的库，两者都具有相同的...
连接模块后，我们就可以看一下第一个例子的Arduino代码了。我们将使用MaxMatrix库，该库可从GitHub下载。

在DIY玩家的眼里,LED最吸引人的用途之一就是制作LED阵列显示屏了。网上有很多自制LED阵列的文章,但大多数都使用Arduino作为驱动板。而最近出现的树莓派Pico(以下简称Pico)更小、速度更快,价格还非常便宜。最棒的地方是Pico能够运行MicroPython,这是一个专用于嵌入式设备的小型Python语言,大大降低了学习成本,提高了开发...
8×8 LED matrix control on an Arduino MegaCreated 31 March 2009, edited 1 Nov 2020 Once you’ve mastered microcontroller programming, you might be tempted to control a lot of LEDs. Lots of people have this desire once they master the basics. Many microcontrollers have a limited number of ...
THE 8 × 8 RGB LED MATRIX DISPLAY AND THE ARDUINOWhen I bought a couple 8脳8 LED displays for about $7.50 each, I had no idea that I would spend the next couple of months trying to figure them out. While there are Arduino shields (for about $20) that will drive this device, it...
一般控制LED阵列的话,每一片8×8的阵列,使用一片max7219(约5元1片,美信公司的芯片都是很贵的)矩阵控制,或者使用两片74HC595锁存器(约0.5元1片)。我买好了两片74HC595,不过想到一片8×8的阵列理论上应该可以直接使用一个89c51来控制(89c51有32个数据脚,arduino脚不够),仿真实验成功,省下了1块钱(2片595),...
