【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 #defineBLINK_GPIO1 3、GPIO操作相关API 代码语
voidsetup{ // 初始化 LED 引脚为输出 pinMode(ledPin, OUTPUT); } voidloop{ // 打开 LED digitalWrite(ledPin, HIGH); delay(1000);// 等待 1 秒 // 关闭 LED digitalWrite(ledPin, LOW); delay(1000);// 等待 1 秒 } 烧录运行,如果接线没错的话,效果在:https://mp.weixin.qq.com/s/tI6YlX...
最好LED灯连接一个220欧的电阻,避免电流过大烧坏了开发板针脚和LED,这里就不加了。 创建项目 首先,打开 VS Code 从模板项目创建 Blink 项目,按F1或选择顶部菜单【查看/命令面板(Ctrl + Shift + P)】,在命令行中输入:esp-idf show,在显示的下来菜单中选择【展示示例项目】 然后选择当前的 ESP-IDF 开发环境,...

然后烧录示例example,ESP_IDF\examples\get-started\blink,发现LED灯不会闪烁,控制台有log输出。源码我只改了GPIO口,将默认的GPIO5改成GPIO8, Code: Select all define BLINK_GPIO 8//CONFIG_BLINK_GPIO.其他的没改。ICY Espressif staff Re: ESP32-C3-DevKitM-1 跑示例程序Blink,RGB灯不闪。 Quote Fri...
