将三个 LED 连接到 ESP32。我们正在使用 GPIO 12、13 和 14。您可以使用任何其它合适的 GPIO。 推荐阅读:ESP32 Pinout Reference:您应该使用哪些 GPIO 引脚? 组织你的文件 为了使项目井井有条并更容易理解,我们将创建四个文件来构建 Web 服务器: 处理Web 服务器的Arduino 程序; index.h
配置GPIO引脚的输入/输出模式:通过gpio_config()函数配置,该函数在头文件driver/gpio.h中定义。 配置GPIO引脚电平触发和中断类型:通过gpio_set_intr_type()函数配置,可选择下降沿触发、上升沿触发、双边沿触发或者禁用中断。该函数在头文件driver/gpio.h中定义。 配置GPIO引脚的下拉/上拉电阻:通过gpio_set_pull_mod...
