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>...
Adafruit_NeoMatrix matrix = Adafruit_NeoMatrix(20, 5, PIN,NEO_MATRIX_TOP + NEO_MATRIX_LEFT+ NEO_MATRIX_COLUMNS + NEO_MATRIX_ZIGZAG, NEO_GRB + NEO_KHZ800); 你可以使用 Adafruit 的GFX库,可以下载高度为5像素的不同的点阵字体。请使用附带的 Arduino sketch 作为起点(使用 PIN 4 作为矩阵的起点)。
