基于潘多拉开发板使用的问题：

配置了I2c总线和软件包，初始化也成功了，但是无法读取数据时怎么回事？有哪位大神帮忙看看？

```c
#include <rtthread.h>
#include <board.h>
#include <rtdevice.h>

#define DBG_TAG "main"
#define DBG_LVL DBG_LOG
#include <rtdbg.h>

/* PLEASE DEFINE the LED0 pin for your board, such as: PA5 */
#define LED0_PIN    GET_PIN(E, 7)
#include "aht10.h"
#include "sensor_asair_aht10.h"
#define AHT10_I2C_BUS  "i2c1"
int rt_hw_aht10_port(void)
{
    struct rt_sensor_config cfg;
    cfg.intf.dev_name  = AHT10_I2C_BUS;
    cfg.intf.user_data = (void *)AHT10_I2C_ADDR;
    rt_hw_aht10_init("aht10", &cfg);
     LOG_D("aht10 is OK!");
    return RT_EOK;
}

int main(void)
{
    rt_err_t  res;
    float humidity, temperature;
    int count = 1;
    aht10_device_t dev;
    rt_hw_aht10_port();
    dev = aht10_init(AHT10_I2C_BUS);
    if (dev == RT_NULL)
    {
    LOG_E(" The sensor initializes failure");
    return 0;
    }
    else
    {
        LOG_D(" The sensor initializes ok!");
    }

/* set LED0 pin mode to output */
    rt_pin_mode(LED0_PIN, PIN_MODE_OUTPUT);

while (count++)
    {
        humidity = aht10_read_humidity(dev);
        rt_kprintf("humidity   : %d.%d %%<br>", (int)humidity, (int)(humidity * 10) % 10); /* former is integer and behind is decimal */

/* read temperature */
        temperature = aht10_read_temperature(dev);
        rt_kprintf("temperature: %d.%d <br>", (int)temperature, (int)(temperature * 10) % 10); /* former is integer and behind is decimal */

rt_thread_mdelay(1000);
        /* set LED0 pin level to high or low */
        rt_pin_write(LED0_PIN, count % 2);
       // LOG_D("Hello RT-Thread!");
        rt_thread_mdelay(1000);
    }

return RT_EOK;
}
```
