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 saving as power is an important factor for IoT ap...

Introducing Deep Sleep Mode If you’ve made a project with an ESP8266 board that is battery powered, or if you just connected your ESP8266 NodeMCU board to a power bank. After running it for a while, you realize the battery doesn’t last long, specially if you’re using Wi-Fi. ...

设置SLEEPDEEP 位,设置 PDDS 位,执行 WFI 指令,进入待机模式. void PWR_EnterSTANDBYMode(void ): 最后编写WK_UP中断函数. 因为我们通过 WK_UP 中断 ( PA0 中断)来唤醒CPU, 所以我们有必要设置一下该中断函 数,同时我们也通过该函数里面进入待机模式 ...
可以通过AON_TIMER_SLEEP_DURATION在0到32760000毫秒之间设置AON计时器 使用AON GPIO 引脚作为唤醒源 对于AMB21,有5个引脚可以设置为AON引脚和上缘触发,PA25(D16)、PA26(D17)、PA21(D26)、PA20(D27)、PA(D28)。 对于AMB23,有8个引脚可以设置为AON引脚和上缘触发,PA12(D9)、PA13(D10)、PA14(D11)...
In Arduino IDE,ESP.deepSleep(uS)function can be used to put ESP8266 into deep sleep mode. We have a similar guide for the ESP32 board in Arduino IDE as well. Click the link below to access it. ESP32 Deep Sleep Mode and Wake Up Sources using Arduino IDE ...
