### 读取传感器数据,上传到阿里云
|
|
||||||
|
### 1. 使用AHT10软件包采集温湿度并上传到阿里云
|
||||||
|
|
||||||
(合并头两个代码),拼接字符串时我用了`sprintf`,其实应该也可以样例原有的`HAL_Snprintf`的

|
||||||
|
|
||||||
|
### 2. 将font分区给挂载上。在温湿度上传上传云端的同时,将数据同步放在文件系统处,
|
||||||
|
文件名为:Data.txt;文件内容:
|
||||||
|
> Temp:XX ; Humi:XX ; Count: 1(自上电起所采集的数据次数)
|
||||||
|
Temp:XX ; Humi:XX ; Count: 2(自上电起所采集的数据次数)
|
||||||
|
Temp:XX ; Humi:XX ; Count: 3(自上电起所采集的数据次数)
|
||||||
|
|
||||||
|
|
||||||
|
在`drv_filesystem.c`中实现挂载font
|
||||||
|
``` c
|
||||||
|
fal_init();
|
||||||
|
fal_blk_device_create("font");
|
||||||
|
/* 创建目录 */
|
||||||
|
ret = mkdir("/fal/test", 0x777);
|
||||||
|
if (ret < 0)
|
||||||
|
{
|
||||||
|
/* 创建目录失败 */
|
||||||
|
rt_kprintf("dir error!\n");
|
||||||
|
}
|
||||||
|
else
|
||||||
|
{
|
||||||
|
/* 创建目录成功 */
|
||||||
|
rt_kprintf("mkdir ok!\n");
|
||||||
|
}
|
||||||
|
/* 挂载块设备"font"到 DFS 目录/fal/test中 */
|
||||||
|
if (dfs_mount("font", "/fal/test", "elm", 0, 0) == 0)
|
||||||
|
{
|
||||||
|
LOG_I("font initialized!");
|
||||||
|
}
|
||||||
|
else
|
||||||
|
{
|
||||||
|
dfs_mkfs("elm", "font");
|
||||||
|
if (dfs_mount("font", "/fal/test", "elm", 0, 0) == 0)
|
||||||
|
{
|
||||||
|
LOG_I("font initialized!");
|
||||||
|
}
|
||||||
|
else
|
||||||
|
{
|
||||||
|
LOG_E("Failed to initialize font!");
|
||||||
|
LOG_D("You should create a filesystem(font) on the block device first!");
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
接着文件末尾添加数据(Data.txt)
|
||||||
|
![alt text](image-7.png)
|
||||||
|
|
||||||
|
``` c
|
||||||
|
void make_file()
|
||||||
|
{
|
||||||
|
//文件描述符
|
||||||
|
int fd;
|
||||||
|
|
||||||
|
//用只写方式打开文件,如果没有该文件,则创建一个文件
|
||||||
|
fd = open("/fal/test/Data.txt", O_WRONLY | O_CREAT | O_APPEND); //和原来相比,只是把O_TRUNC参数更改为O_APPEND,即更改为打开后,如果再进行写入,将从文件的末尾位置开始写。
|
||||||
|
// rt_kprintf("\n%f %f tmp:%s\n",Humi,Temp,String);
|
||||||
|
//如果打开成功
|
||||||
|
if (fd >= 0)
|
||||||
|
{
|
||||||
|
//写入文件
|
||||||
|
write(fd, tmp, sizeof(tmp));
|
||||||
|
|
||||||
|
// rt_kprintf("Write done.\n");
|
||||||
|
|
||||||
|
//关闭文件
|
||||||
|
close(fd);
|
||||||
|
}
|
||||||
|
else
|
||||||
|
{
|
||||||
|
rt_kprintf("File Open Fail.\n");
|
||||||
|
}
|
||||||
|
|
||||||
|
|
||||||
|
return;
|
||||||
|
}
|
||||||
|
```
|
||||||
|
### 3. 利用云端给开发板发送指令然后实现小灯翻转
|
||||||
|
```c
|
||||||
|
rt_pin_mode(GPIO_LED_R, PIN_MODE_OUTPUT);
|
||||||
|
//topic_info->payload 为发送的内容,可以据此设置命令
|
||||||
|
if(rt_pin_read(GPIO_LED_R) == PIN_HIGH)
|
||||||
|
{
|
||||||
|
// rt_kprintf("LED_R should be ON\n");
|
||||||
|
rt_pin_write(GPIO_LED_R, PIN_LOW);
|
||||||
|
}
|
||||||
|
else
|
||||||
|
{
|
||||||
|
// rt_kprintf("LED_R should be OFF\n");
|
||||||
|
rt_pin_write(GPIO_LED_R, PIN_HIGH);
|
||||||
|
}
|
||||||
|
```

||||||
