发现rt-thread各版本之间真乱，对新手非常不友好。经过排查发现问题出在如下位置。
在pin.h中的定义

```c
struct rt_pin_ops
{
    void (*pin_mode)(struct rt_device *device, rt_base_t pin, rt_uint8_t mode);
    void (*pin_write)(struct rt_device *device, rt_base_t pin, rt_uint8_t value);
    rt_int8_t  (*pin_read)(struct rt_device *device, rt_base_t pin);
    rt_err_t (*pin_attach_irq)(struct rt_device *device, rt_base_t pin,
            rt_uint8_t mode, void (*hdr)(void *args), void *args);
    rt_err_t (*pin_detach_irq)(struct rt_device *device, rt_base_t pin);
    rt_err_t (*pin_irq_enable)(struct rt_device *device, rt_base_t pin, rt_uint8_t enabled);
    rt_base_t (*pin_get)(const char *name);
};
```
在drv_gpio.c中使用的时候变成了如下

```c
const static struct rt_pin_ops _stm32_pin_ops =
{
    stm32_pin_mode,
    stm32_pin_write,
    stm32_pin_read,
    stm32_pin_attach_irq,
    stm32_pin_dettach_irq,
    stm32_pin_irq_enable,
};
```

```c
static void stm32_pin_mode(rt_device_t dev, rt_base_t pin, rt_base_t mode)
static void stm32_pin_write(rt_device_t dev, rt_base_t pin, rt_base_t value)
static int stm32_pin_read(rt_device_t dev, rt_base_t pin)
static rt_err_t stm32_pin_attach_irq(struct rt_device *device, rt_int32_t pin,
                                     rt_uint32_t mode, void (*hdr)(void *args), void *args)
static rt_err_t stm32_pin_irq_enable(struct rt_device *device, rt_base_t pin,
                                     rt_uint32_t enabled)
```
可以看到变量定义一会rt_uint8_t一会rt_base_t多么的随意。
