ret = GpioSetDir(gpio, GPIO_DIR_OUT); if (ret != 0) { HDF_LOGE("GpioSerDir: failed, ret %d\n", ret); return ret; } if (mode == -1) { // 翻转输出口 (void)GpioRead(gpio, &valRead); ret = GpioWrite(gpio, (valRead == GPIO_VAL_LOW) ? GPIO_VAL_HIGH : GPIO_VAL_LOW...
Out of memory. Remarks The GPIO controller driver calls this method to register its event callback functions with GpioClx. Typically, the driver calls this method from itsDriverEntryroutine, which runs shortly after the driver is loaded into memory. ...
// Zephyr中的设备驱动函数表 struct gpio_driver_api { int (*pin_configure)(const struct device *dev, gpio_pin_t pin, gpio_flags_t flags); int (*pin_set)(const struct device *dev, gpio_pin_t pin, bool value); // 其他驱动函数... }; 优势:降低驱动调用开销,适合资源受限的嵌入式系统。
GPIO_Mode_AN = 0x03 /*!< GPIO Analog In/Out Mode */ }GPIOMode_TypeDef;这个结构体定义了端口的模式。分别是：输入、输出、复用、模拟输入。默认状态下是普通IO口，也就是输入或输出，此时单片机的端口只能输入或输出高低电平，不能用于其他外设（例如PWM、UART、SPI等）。那么如果这个端...
