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
What is the expected Deep Sleep current consumption of the ESP32-WROOM-32D (or E) module? In the datasheet I can only find reference to the ESP32 chip that its sleep current can be as low as 5uA. I cannot find the same information for the module. Also if the numbers are different...
This is needed for modules // which have an external pull-up resistor on GPIO12 (such as ESP32-WROVER) // to minimize current consumption. rtc_gpio_isolate(GPIO_NUM_12);//将12脚隔离 printf("Entering deep sleep\n"); gettimeofday(&sleep_enter_time, NULL);//获取进入睡眠的时间 esp_...
deep sleep电流(断开mA表) 电流小于10uA。 6. 添加一个LED作为gpio的负载 6.1 添加gpio负载 添加对电源的负载(灌电流 sink current) GPIO_NUM_2,GPIO_NUM_4和GPIO_NUM_15这几个引脚添加对地负载(拉电流 source current)会使深度睡眠电流增大到60uA以上。像后面所附的电路图那样连接LED1是不行的,要将LED的...
