【玩转ESP32】3、点亮LED,Blink,blink,blink 可以看出LED对应的GPIO编号是GPIO1。 2、使用idf中的例程改造 对idf里面的demo进行改造,在examples\get-started\blink里面更改GPIO口: 代码语言:javascript 代码运行次数:0 AI代码解释 #defineBLINK_GPIO1 3、GPIO操作相关API 代码语言:javascript 代码运行次数:0 运行 AI...
I opened the default example Blink.ino in Arduino IDE, just added LED_BUILTIN and those Serial.* to see something happening in the console, but the ESP32 LED just flickers everytime it is set to HIGH or LOW. (Serial output is working) I don't get the LED to stay ON... Code: ...

首先用vscode打开自己的arduino目录,然后新建文件夹Blink再新建一个Blink.ino文件。 我们先点击下面状态栏中的<Select Board Type>选择开发板类型,选择NodeMCU1.0(ESP-12F Module) 连接上我们的开发板,并且点击下面状态栏的<``Select Serial Port>,找到自己ESP8266的设备端口。 配置完就可以编写代码了 这时候如果编写...

这里可对特定的开发板进行配置,比如:内置的 LED 灯对应的IO脚进行设置,因为该项目没用使用 GPIO, 故这里不用做任何操作,直接关闭即可,如下图所示: 编译工程 点击【build】图标按钮进行构建,如下图所示: 然后开始构建: 过程有点漫长,请耐心等待...

ESP32-CAM 有一个与 GPIO33 连接的内置LED。因此,相应地更改 Blink 草图: #define LED_BUILT_IN 33 void setup() {pinMode(LED_BUILT_IN, OUTPUT); // Set the pin as output } // Remember that the pin work with invertedlogic// LOW to Turn on and HIGH to turn off void loop() { digital...
