【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: ...

const int LED_BUILTIN = 2; 1. const关键字代表常量。它修改了变量的行为,使得该变量可以像其类型的任何其他变量一样使用。也就是说,LED_BUILTIN就是管脚2。 (4)验证上传 成功。 如果要修改灯的闪烁,就修改延时时间就可以了。 接下来我在DFROBOT网站上学习,第二个简单项目是利用LED输出SOS。实际上就是利用...

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...
