程序附件下载解压后,用Arduino IDE打开程序烧录进去pro mini就可以去卖萌了。 LED-Matrix-Editor这是个在线编辑点阵LED图案的工具,可以自己改成自己喜欢的图案,然后复制代码到表情包程序里修改表情。 转自DF社区-好奇吖斌
Arduino LED Matrix Max7219 + 8x8 LED Matrix 滚动显示 I ️ U。 算法很简单,首先定义滚动画面8x32矩阵。通过generate_8x8_matrix函数生成当前循环中应当显示的8x8矩阵,通过LedControl模块的setLed设置对应的点阵即可。 不要放太久,因为times是一个int型,并未进行溢出情况的处理。 1#include <LedControl.h>...
要驱动该点阵屏有2种方式,一种是以常规的Arduino开发板来驱动,另一种则是以ESP32-E Arduino开发板来驱动。 对于常规的Arduino开发板驱动,在使用前安装对应的FireBeetleLEDMatrix-master库,安装后即可见到对应库以供使用。 若以ESP32-EArduino开发板来驱动,则无法直接进行编译和上传,为此只好以I/O口驱来编程实现。

Arduino 该矩阵可直接在 Arduino 设备上使用 Adafruit 的 NeoPixel 库和NeoMatrix 库。如果你使用下面的用例,则必须修改 PIN 并初始化:NeoMatrix:1 Adafruit_NeoMatrix matrix = Adafruit_NeoMatrix(20, 5, PIN,NEO_MATRIX_TOP + NEO_MATRIX_LEFT+ NEO_MATRIX_COLUMNS + NEO_MATRIX_ZIGZAG, NEO_GRB + NEO_KHZ...
8*8 LED RGB Matrix是一个XY轴可任意级联的三色多彩LED显示矩阵模块,可用于显示图片和文字,支持多图层和各图层的各种平移效果。 理论上支持X轴横向最大4096个和Y轴纵向最大4096个模块的任意级联,无需设计硬件。当然,如果您想要把它们级联成一个大型矩阵显示屏的话,那么您就需要一个高速控制器和大功率电源。
