+ } + + HAL_GPIO_WritePin(index->gpio, index->pin, (GPIO_PinState)value); +} +``` + +另 +`_pin_write`则服务于I/O设备管理接口,如`rt_device_write`，实际上，也是调用的上文所述的`pin->ops->pin_write`,~~有点困惑这样不是又调用回`_pin_write`自己了吗~~ +``` +static rt_size_t _pin_write(rt_device_t dev, rt_off_t pos, const void *buffer, rt_size_t size) +{ + struct rt_device_pin_status *status;

+ + pin->ops->pin_write(dev, (rt_base_t)status->pin, (rt_base_t)status->status); + + return size; +} +``` +### 疑惑： +1. 为什么`_pin_write`会调用`stm32_pin_write`？ +1. `struct rt_device_pin *pin = (struct rt_device_pin *)dev;`之后ops怎么就变成_hw_pin的ops了呢 +### 回答 +1. 其实是同一个问题，因为`rt_pin_device`的第一个元素就是`rt_device`类型的`parent`,也就是说他们(rt_pin_device _hw_pin和_hw_pin.parent)的首地址是一样的，当强制转换为`rt_pin_device`时，也就可以用上地址紧接在后面的ops了。 +2. pin设备自始至终用的都是`pin.c`开头定义的_hw_pin设备 + + + +`_pin_write`也是在上文的`rt_device_pin_register`中被赋值的，这里的`pin_ops`也这几个函数 + +``` +int rt_device_pin_register(const char *name, const struct rt_pin_ops *ops, void *user_data) +{ + #ifdef RT_USING_DEVICE_OPS + _hw_pin.parent.ops = &pin_ops;

+ #endif + …… +} +``` +最终他们会在I/O设备管理接口,如`rt_device_write`中被调用，如下 +``` +#ifdef RT_USING_DEVICE_OPS +#define device_init (dev->ops->init) +#define device_open (dev->ops->open) +#define device_close (dev->ops->close) +#define device_read (dev->ops->read) +#define device_write (dev->ops->write) +#define device_control (dev->ops->control) +#else +#define device_init (dev->init) +#define device_open (dev->open) +#define device_close (dev->close) +#define device_read (dev->read) +#define device_write (dev->write) +#define device_control (dev->control) +#endif /* RT_USING_DEVICE_OPS */ + +rt_size_t rt_device_write(rt_device_t dev, + rt_off_t pos, + const void *buffer, + rt_size_t size) +{ + /* parameter check */ + RT_ASSERT(dev != RT_NULL);
