The ESP8266 isn’t necessarily better than Arduino—it’s different. While the Arduino excels at general-purpose microcontroller tasks, the ESP8266 shines when you need built-in Wi-Fi capabilities. If your project requires wireless communication, the ESP8266 may be a better choice. Otherwi...
各引脚分别作为输入输出时的推荐程度和注意事项说明,图片截图自:https://randomnerdtutorials.com/esp8266-pinout-reference-gpios/ ESP12引脚图,引脚图适用于12E/F,以及原版8266模块 其实图表已经把功能成系列的引脚归类排列在一起了,根据注意事项翻译过来就是: GPIO0(D3):连接到NODEMCU为代表的FLASH按键开关上,作...
If you take a look at the NodeMCU pinout, you can see that GPIO 16 is a special pin and it has a WAKE feature. Recommended reading:ESP8266 Pinout Reference Guide The RST pin of the ESP8266 is always HIGH while the ESP8266 is running. However, when the RST pin receives a LOW signal...
TL; DR 代码见GitHub Gist: Jamesits/high-frequency-square-wave-generator-esp8266.ino 继在Arduino UNO上实现了高频方波发生器之后,我把魔爪伸向了便宜量足的ESP8266。它能不能产生符合要求的高频波形呢? 初测 分析ESP8266 Arduino SDK的 digitalWrite() 实现后发现,ESP8266的IO分为两组:0-15号,由同一组寄存...

首先,在RPi上标识 3.3V电源 和 GND(接地) 》引脚为ESP8266微控制器供电, TXD(发送) 和 RXD(接收) 引脚进行通信,并且 两个通用引脚 来操作ESP8266(可以将其设置为高电平或低电平)。在pinout.xyz上查找引脚排列或输入端子: $ pinout 其次确定ESP-01上的必要引脚。但是从一开始我们就需要了解ESP-01引脚。我在...
GPIO 0-15引脚都配有内置上拉电阻。这一点与Arduino十分类似。GPIO16 引脚配有内置下拉电阻。 Esp8266芯片的模拟输入 ESP8266 只有一个模拟输入引脚(该引脚通过模拟-数字转换将引脚上的模拟电压数值转化为数字量)。 此引脚可以读取的模拟电压值为 0 – 1.0V。请注意:ESP8266 芯片模拟输入引脚连接在1.0V以上电压可...
