set_sleep_mode(SLEEP_MODE_PWR_DOWN);// 设置休眠模式 sleep_mode();// 进入休眠状态 1. 2. 3. 注意: sleep_mode 为宏指令,它会自动自动开启休眠功能、进入睡眠状态、禁用休眠功能。 按照官方解释,在某些条件下, sleep_mode 宏会导致个别操作步骤开启休眠功能并发出sleep指令进入休眠,所以,另外提供

Different types of Arduino board have different numbers of interrupts pins e.g. Arduino UNO have two interrupt ports and Arduino Mega2560 have six interrupt ports named as INT1,INT0. On the software side create sleep mode for Arduino and use a timer base interrupts which would internally be e...
In this tutorial, you’ll learn how to use ESP32 interrupt pins in Arduino Core. We’ll also discuss how to use interrupts and write your interrupt service routine (ISR) for ESP32 external interrupt GPIO pins. Then, we’ll move to the Arduino Core libraries that implement drivers for the...
调用esp_deep_sleep_start() 函数,进入 Deep-sleep 模式 此时需要周期性唤醒 ESP32,不能充分利用 ESP32 的低功耗性能,但可以进行复杂的传感器数据采集 /* Simple Deep Sleep with Timer Wake Up ESP32 offers a deep sleep mode for effective power ...
ESP32 offers a deep sleep mode for effective power saving as power is an important factor for IoT applications. In this mode CPUs, most of the RAM, and all the digital peripherals which are clocked from APB_CLK are powered off. The only parts of ...
Enter sleep mode (after a timeout). The argument is in minutes. A value of 0 disables an active timer. The method cannot be used to wake up the MCU, since it might really be asleep and require an external interrupt to wake up. FunctionSupportCheck 0 Check whether system variables can ...
When you set the ESP32 in Access Point mode, this allows it to create a Wi-Fi network. This means you’ll have your own WiFi network and no need for an external router to connect your devices. Other devices (stations) can easily connect to the ESP32’s network and communicate with it...
