使用。使用下面的函数以区别于正常的GPIO int gpio_get_value_cansleep(unsigned gpio);//读GPIO void gpio_set_value_cansleep(unsigned gpio, int value);//写GPIO --- 这句话的意思:如果soc本身(比如100个)gpio不够用, 那么就要另外接一个gpio controller, 上面再提供额外的50个gpio,这个con...
此函数返回一个包含描述符数组的struct gpio_descs。它还包含指向gpiolib私有结构的指针,如果传递回get/set数组函数,可能会加快I/O处理: structgpio_descs{ structgpio_array*info; unsignedintndescs; structgpio_desc*desc[]; } 以下函数在没有将任何GPIO分配给请求的功能时返回NULL: ...

That is technically incorrect: the ESP32-C6 can access all peripherals except the ones quoted because it has full access to the same bus as the main processor. I'll ask if there is a more 'native' way that also works in deep sleep; I agree that esp-idf and the documentation don't ...
The value of the button board is a tuple of all the buttons states. This can be used to control all the LEDs in a LEDBoard with a ButtonBoard: 扩展自组合设备(CompositeDevice)代表一个通用的按钮板,或者按钮集合。按钮板的值是所有按钮状态的元组值。可以使用按钮板的按钮控制发光二极管板子上的 ...
