但是,如果不将 XBee 3 pro 和常规模块连接到电脑,您可能无法区分它们。例如,PCB 选项 XBee 3 pro 和常规模块看起来完全相同,但在电路板顶部用黑色墨水印刷有细微的差异。常规模块(我正在使用的批次)标有“109 202”,而专业模块标有“941 201”如果您使用 XBee 3 模块,您可能想要在 pro 模块上做一个小标记,...
using the oscilloscope to catch a PWM jitter. Tinkercad and Wokwi were offline casualties, but SimulIDE thrived. Later, Proteus confirmed our findings with more polish, but SimulIDE’s free price was unbeatable.
Arduino可以调节一个LED的亮度,却不改变施加在LED上的电压,这是利用了一种专门的技术,称为脉冲宽度调制(PWM),或者简称脉宽调制(后面会详细讲解)。除了可以利用脉宽调制进行模拟输出以外,Arduino 还可以接受0～5V 的模拟输入。 标准的Arduino有6 个模拟输入引脚,标注为ANALOG INA0、A1、A2、A3、A4、A5;另外,还有6...
begin(int sda=-1,int scl=-1,uint32_t frequency=0); 这是这个初始化代码的调用方式 参数什么的 在文档中这里应该是硬件实现的I2C,SPI等接口 重点可以看I2C的参数参数 ESP32有两个I2C控制器(也称为端口),负责处理两条I2C总线上的通信。每个I2C控制器都可以作为主机或从机运行。引脚21 默认的SDA, 引脚22...
In addition, we will see how altering the PWM frequency can improve performance tremendously.Read More » Using OLED Displays with Arduino OLED displays are bright, lightweight and visible under a wide range of lighting conditions. They are available with both I2C and SPI interfaces and in this...

The repeat frequency for the pulses on all PWM outputs can be changed with the new functionanalogWriteFrequency(kHz), wherekHzvalues of 1 (default), 4, 8, 16, 32 and 64 are supported. Note that these values are very approximate. The best effort within the constraints of the hardware will...
