Hardware Interrupts– These areinterrupts that are being fired by hardware peripherals or sources. They can be: Internal or External. An example of aninternal hardware interrupts may be something like a hardware timer interrupt or WDT. An example of an external hardware interrupt is external GPIO ...
ESP-IDF Timer Interrupt Example We will build and create a project in VS Code with ESP-IDF extension whereby a timer interrupt will be used to toggle the onboard LED of ESP32. The LED will be set up as a digital output and will be toggled after a set number of intervals. Lets show ...
* GPIO19: output (ESP32C2/ESP32H2 uses GPIO9 as the second output pin) * GPIO4: input, pulled up, interrupt from rising edge and falling edge * GPIO5: input, pulled up, interrupt from rising edge. * * Note. These are the default GPIO pins to be used in the example. You can *...

The macro __NOINIT_ATTR can be used as attribute to place data into .noinit section. The values placed intothissection will not be initialized at startup and keep its value after software restart. Example: __NOINIT_ATTR uint32_t noinit_data; ...

Smart_Config的初始化函数,回调函数,任务函数都直接复制Smart_configDemo中的即可,但是得注意 其中的任务smartconfig_example_task配网结束后需要删除,节约空间,如下图: 1.2 周期上报数据(Timer) 周期上报数据使用硬件定时器方式,使能一个 自动重装载的定时器,在定时器中断函数中改变状态位,提醒需要上报数据,需要的代码...
