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,另外提供了以下三...

How to set up an external interrupt The two functions you need to activate an interrupt: attachInterrupt( <interrupt>, my_isr_function, mode ). digitalPinToInterrupt( <Arduino pin> ). Other related functions are: detachInterrupt(digitalPinToInterrupt(pin))- Detaches a specified interrupt - so ...

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 ...

Warning:Do not use delay() in an interrupt routine. since it uses interrupts itself the interrupt routine would hang. Instead use delayMicroseconds() - That function creates hard coded delays that are interrupt safe. So the question now becomes how do you actually create a delay but at the ...
