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> 2 3 int DIN = 12; 4 int CS = 11; 5 int CLK = 10; 6 7 char TOTAL[8][32] = { 8 {0, ...
电源 100个 WS2812b LED 的最大功率为 100x60mA = 6A。当然,如果降低亮度,功率损耗也会大大降低。5V 电源能够达到你想要的亮度。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:...
点阵屏(Dot matrix screen)指在显示屏上长和宽各能显示出多少个像素点,或者在LED显示屏上长和宽有多少个LED会同时发光。 2023-02-14 15:25:59 点阵液晶屏和段码液晶屏的区别 LCD液晶屏的分类有很多,大致分为单色液晶屏、点阵液晶屏、段码液晶屏和TFT彩色液晶屏等。在众多分类中点阵液晶屏和段吗液晶屏有什...
