我们都知道Arduino的LED灯是连接在13号引脚,但是在其它平台,这就不一定了,像在ESP-LAUNCHER开发板上,就没有默认的LED,怎么办,设置这里就可以了 参考官方原理图,这里可以使用GPIO12来做试验。 接下来就可以使用ARDUINO的blink程序来测试了,代码太常见,不上了! 说下插曲,按官方的文档,直接将GPIO0开关拔下来,就可以...
Dual In Line", like the pins of DIP ICs. Many ESP-xx modules include a small on-board LED which can be programmed to blink and thereby indicate activity. There are several antenna options for ESP-xx boards including a trace antenna, an on-board ceramic ...
顶部菜单栏>文件>示例>01.Basics>Blink.打开示例代码,该代码仅仅控制一个LED闪烁,LED_BUILTIN为开发板厂商定义的LED引脚,可自行修改,如改为3,便是GPIO3。点击上传,开始编译文件并烧录工程,nodeMCU可以直接烧录,如果是自己的模块可能需要短按复位,遇到该问题可留言咨询。
// GPIO 2 (D5) has a LED_BLINK attached to it. Give it a name: int LED_BLINK = 2; // the setup function runs once when you press reset or power the board void setup() { // initialize digital pin LED_BUILTIN as an output. pinMode(LED_BLINK, OUTPUT); } // the loop functi...

问esp 8266问题“离开...正在通过RTS引脚硬重置...”ENESP8266的GPIO(1,3,9,10)不能按常规的GPIO方式进行理解和使用，根据ESP8266的系统(SoC)设计，其内部包含了处理器芯片等组件，处理器有17GPIO线路，其中一些GPIO规定默认用于与其他内部组件进行通信，比如与内部闪存的通信等。这样我们大约还有11个GPIO引脚可按...
