安装完后打开软件,选择Intelligent backlight display,我们从上到下一一设置。首先要勾选Use backlight,否则灯带不会跟着屏幕变化。阅读全文:https://dwz.cn/fXEwlj5n 神0035855 崭露头角 2 您好,我这边左后测试的时候为什么报错呀! 神0035855 崭露头角 2 In file included from C:\Users\�Ǻ�\...
The wiring diagram below shows you how to connect the MAX7219 LED dot matrix display to the Arduino.Note that when using the MD_Parola library, you need to orient the display with the DIN connector on the right, otherwise the text will be printed upside down.For more information seethe sect...
为LED显示器的芯片布线,注意显示器要与前板外部齐平。 调试电压 在将电压升压器焊接到电路之前,请确保使用芯片上的电位计的输出电压调整为5V。 软件部分 1、下载并安装 Arduino 软件。 https://www.arduino.cc/en/Main/Software。如果你得到图片中的提示信息,请同意并安装。 (代码和库http://bit.ly/arduinoco...
你把输入值匹配到输出的范围,在这里就是10个LED灯。然后你设置一个循环重复这些输出。如果输出的数字比匹配输入范围要低时,打开LED灯。否则,关闭LED灯。 /* LED bar graph Turns on a series of LEDs based on the value of an analog sensor. This is a simple way to make a bar graph display. Though...
