First, configure the wake-up sources. This means configuring what will wake up the ESP32. You can use one or combine more than one wake-up source. This article shows you how to use the timer wake-up. Use theesp_sleep_enable_timer_wakeup()function and pass as argument time sleep time ...
esp_sleep_enable_timer_wakeup(TIME_TO_SLEEP* uS_TO_S_FACTOR); Serial.flush(); esp_deep_sleep_start();The device does enter deep sleep and then awakes on its own after the 60 second time interval. However, the awake time is very brief before it returns to deep sleep. I tried introdu...
1.1 深度睡眠Deep-sleep ESP32具有Light-sleep和Deep-sleep两种睡眠节能模式。 在Light-sleep模式下,数字外设、CPU、以及大部分RAM都使用时钟门控,同时电源电压降低。退出该模式后,数字外设、CPU和RAM恢复运行,内部状态保持不变。 在Deep-sleep模式下,CPU、大部分RAM、以及所有由时钟APB_CLK驱动的数字外设都会被断电。
When waking up from deep sleep, the ESP32 can run a deep sleep wake stub. It’s a piece of code that executes as soon as the chip wakes up, before any normal initialization, bootloader, or ESP-IDF code is executed. After executing the wake stub, the chip can either return to sleep...
On my project i am using deep sleep feature of esp32. My device can awaken by timer and internal button too. When i go to sleep with adjusted time(timer deep sleep, constant 12h) Someone can push to button and awaken my device. If this scenario occurs my timer wake up time will shif...
ESP32 Timer as a wake-up resource from a deep sleep, put ESP32 into deep sleep mode and wake it up using a predefined time
程序配置某一个 RTC IO 为 wake_up IO. 当采用高电平唤醒时, 外部采用 10K 欧电阻下拉, 当采用低电平唤醒时, 外部采用 10K 欧电阻上拉. EXT0 唤醒方式测试结果中, 配置 GPIO_0 为 wake_up IO 时, 如果是配置低电平唤醒, deep_sleep 期间工作电流是 6.3uA, 配置成高电平唤醒时, deep_sleep 期间工作...
