# 软件包和组件
|
|
||||||
## 软件包（Software Package）
|
|
||||||
帮助我们完成了底层驱动的编写，我们只需要使用里面提供的API就好了，帮助我们快速开发。
|
|
||||||
RT-Thread 软件包中心：[软件包](https://packages.rt-thread.org/index.html)
|
|
||||||
ENV Kconfig配置文件
|
|
||||||
|
|
||||||
### 温湿度传感器——AHT10（I2C设备）
|
|
||||||
#### 配置
|
|
||||||
在menuconfig选择,最终在[**Kconfig这里**](board\Kconfig)使能（勾选上宏）
|
|
||||||
1. 使能驱动AHT21(AHT10也适用，且会同时使能软件包)
|
|
||||||
|
|
||||||
2. 记得 `pkg --update`
|
|
||||||
3. 补充rt_vsnprintf_full软件包，使kprintf可以用`%.3f`（可以按`/`搜索）
|
|
||||||
|
|
||||||
4. 还是要记得 `pkg --update`
|
|
||||||
|
|
||||||
使用直接驱动的[这个ath10.c](packages\aht10-latest\aht10.c)就行了
|
|
||||||
|
|
||||||
#### AHT10样例代码
|
|
||||||
``` c
|
``` c
|
||||||

### MQTT协议（搭配阿里云）
|
|
||||||
#### 原理
|
|
||||||
MQTT（Message Queuing Telemetry Transport）是一种轻量级、基于**发布-订阅**模式的消息传输**协议**(基于TCP/IP?)，适用于资源受限的设备和低带宽、高延迟或不稳定的网络环境。它在**物联网**应用中广受欢迎，能够实现传感器、执行器和其它设备之间的高效通信。如果有设备需要获取某个传感器的消息，只需要**订阅这个主题**就好了。
|
|
||||||
#### 运行框架
|
|
||||||
**Client**：客户端，即我们使用的设备。
|
|
||||||
|
|
||||||
使用MQTT的程序或设备。客户端总是通过网络连接到服务端。它可以
|
#ifdef BSP_USING_FLASH_FS_AUTO_MOUNT
|
||||||
|
#ifdef BSP_USING_FLASH_FATFS
|
||||||
|
#define FS_PARTITION_NAME "filesystem"
|
||||||
|
|
||||||
- 发布应用消息给其它相关的客户端。
|
static int onboard_fal_mount(void)
|
||||||
- 订阅以请求接受相关的应用消息。
|
|
||||||
- 取消订阅以移除接受应用消息的请求。
|
|
||||||
- 从服务端断开连接。
|
|
||||||
|
|
||||||
**Server**：服务端
|
|
||||||
|
|
||||||
作为发送消息的客户端和请求订阅的客户端之间的中介。服务端
|
|
||||||
|
|
||||||
- 接受来自客户端的网络连接。
|
|
||||||
- 接受客户端发布的应用消息。
|
|
||||||
- 处理客户端的订阅和取消订阅请求。
|
|
||||||
- 转发应用消息给符合条件的已订阅客户端。
|
|
||||||
|
|
||||||
**Topic Name**：主题名
|
|
||||||
|
|
||||||
附加在应用消息上的一个标签，服务端已知且与订阅匹配。服务端发送应用消息的一个副本给每一个匹配的客户端订阅。
|
|
||||||
|
|
||||||
**Subscription**： 订阅
|
|
||||||
|
|
||||||
订阅相应的主题名来获取对应的信息。
|
|
||||||
|
|
||||||
**Publish**：发布
|
|
||||||
|
|
||||||
在对应主题上发布新的消息。

|
|
||||||
|
|
||||||
#### 阿里云搭建
|
|
||||||
|
|
||||||
平台：[https://www.aliyun.com/product/iot/iot_instc_public_cn](https://www.aliyun.com/product/iot/iot_instc_public_cn)
|
|
||||||
|
|
||||||
1. **控制管理台** → **注册登录** → 公共实例 → （左栏）设备管理 → 产品 → 创建产品（名称随便，其它默认）→
|
|
||||||
2. Topic 类列表 → 自定义 Topic → 将get的权限改为“发布和订阅”
|
|
||||||
3. 功能定义 → 前往编辑草稿 → 添加自定义功能（标识符发布时要用，步长即精度）→ 发布上线
|
|
||||||
4. 创建设备（产品选择之前创建的）
|
|
||||||
5. 打开RW007(网络连接)，注意修改对应数字
|
|
||||||
|
|
||||||
6. menuconfig 阿里云软件包配置相应名称密码（在对应**产品**页顶端，**设备**页**MQTT连接参数**点击“查看”），同时**使能下方sample**（图中没标出）
|
|
||||||
|
|
||||||
7. `pkg --update`
|
|
||||||
8. 把此处[packages\ali-iotkit-v3.0.2\ports\wrapper.c](packages\ali-iotkit-v3.0.2\ports\wrapper.c)的`RT_WEAK`改为`rt_weak`
|
|
||||||
#### MQTT样例
|
|
||||||
1. 以下代码实现拼接，`DEMO_PRODUCT_KEY, DEMO_DEVICE_NAME`分别替代两个`%s`
|
|
||||||
``` c
|
|
||||||
const char *fmt = "/sys/%s/%s/thing/event/property/post";
|
|
||||||
//...
|
|
||||||
HAL_Snprintf(topic, topic_len, fmt, DEMO_PRODUCT_KEY, DEMO_DEVICE_NAME);
|
|
||||||
```
|
|
||||||
1. 这个报错不用管`E/[RW007]: The wifi Stage 1 status 0 0 0 1`
|
|
||||||
2. 编译、运行、输入`wifi join wifiname wifisecret`
|
|
||||||
3. 在阿里云网页日志服务可以查看发送的消息
|
|
||||||
4. 在阿里云网页对应设备Topic列表可以发布消息（msh中可以收到）
|
|
||||||
5. 发现运行时，shell命令用不了了，因为样例导出的命令用shell线程去跑
|
|
||||||
6. 要把导出的封装为线程,即加入以下内容且把`mqtt_example_main()`的参数改为`void *parameter`
|
|
||||||
|
|
||||||
``` c
|
|
||||||
#define THREAD_PRIORITY 25
|
|
||||||
#define THREAD_STACK_SIZE 4096
|
|
||||||
#define THREAD_TIMESLICE 5
|
|
||||||
|
|
||||||
rt_thread_t MQTT_Thread = RT_NULL;
|
|
||||||
|
|
||||||
void MQTT_Creat_Thread(void)
|
|
||||||
{
|
{
|
||||||
MQTT_Thread = rt_thread_create("MTQQ_Thread", mqtt_example_main, RT_NULL, THREAD_STACK_SIZE, THREAD_PRIORITY, THREAD_TIMESLICE);
|
/* 初始化 fal 功能 */
|
||||||
|
extern int fal_init(void);
|
||||||
if (MQTT_Thread != RT_NULL)
|
extern struct rt_device *fal_blk_device_create(const char *parition_name);
|
||||||
|
fal_init();
|
||||||
|
/* 在 spi flash 中名为 "filesystem" 的分区上创建一个块设备 */
|
||||||
|
struct rt_device *flash_dev = fal_blk_device_create(FS_PARTITION_NAME);
|
||||||
|
fal_blk_device_create("font");
|
||||||
|
if (flash_dev == NULL)
|
||||||
{
|
{
|
||||||
rt_thread_startup(MQTT_Thread);
|
LOG_E("Can't create a block device on '%s' partition.", FS_PARTITION_NAME);
|
||||||
}
|
}
|
||||||
else
|
else
|
||||||
{
|
{
|
||||||
rt_kprintf("MQTT Thread Create Failed!\n");
|
LOG_D("Create a block device on the %s partition of flash successful.", FS_PARTITION_NAME);
|
||||||
}
|
}
|
||||||
|
|
||||||
}
|
/* 挂载 spi flash 中名为 "filesystem" 的分区上的文件系统 */
|
||||||
MSH_CMD_EXPORT(MQTT_Creat_Thread, create a MQTT_Thread);
|
if (dfs_mount(flash_dev->parent.name, "/fal", "elm", 0, 0) == 0)
|
||||||
```
|
|
||||||
## 组件
|
|
||||||
可以独立开发、测试、测试、部署和维护的软件单元
|
|
||||||
*与软件包关系： 组件如手脚，软件包如工具，都可以选择是否使用*
|
|
||||||
|
|
||||||
### 文件系统
|
|
||||||
用板载的W25Q64（Flash）来学习
|
|
||||||
#### 文件系统定义
|
|
||||||
DFS, Device File System, RTT提供的虚拟文件系统组件
|
|
||||||
#### 文件系统架构
|
|
||||||
统一**根目录**用`/`表示，可以挂载目录、文件，允许不同目录下的**同名文件**
|
|
||||||
|
|
||||||
POSIX：一个协议，统一api名称，使代码可以在不同的操作系统中跑
|
|
||||||
ELM FATFS 文件系统：常用，RomFS系统：只读 （下文继续介绍）
|
|
||||||
|
|
||||||
#### 文件系统种类
|
|
||||||
| 类型 | 特点 |
|
|
||||||
| - | - |
|
|
||||||
| FatFS | 小型嵌入式设备，兼容微软，有良好的硬件无关性，RTT最常用，如:elm_fat |
|
|
||||||
| RomFS | 挂载根目录，只读 |
|
|
||||||
| DevFS | 设备文件系统，开启后设备在`/dev`虚拟成文件，可用read、write接口 |
|
|
||||||
| UFFS | 图文开发，用于Nand Flash，快、资源消耗少、免费 |
|
|
||||||
| NFS | 网络文件系统，用于网络连接操作另一台设备 |
|
|
||||||
#### POSIX接口层
|
|
||||||
一个协议，统一api名称，使代码可以在不同的操作系统中跑
|
|
||||||
**4个重要接口**
|
|
||||||
|
|
||||||
文件描述符：fd(file descriptor),对应一个文件，可能多对一（把我们找到需要的文件）
|
|
||||||
还有：
|
|
||||||
``` c
|
|
||||||
int rename(const char *old, const char *new); //重命名
|
|
||||||
int stat(const char *file, struct stat *buf); //取得状态
|
|
||||||
int unlink(const char *pathname); //删除文件
|
|
||||||
```
|
|
||||||
#### 目录管理
|
|
||||||
目录常用api
|
|
||||||
|
|
||||||
#### 文件系统启动流程
|
|
||||||
| 名称 | 补充 |
|
|
||||||
| - | - |
|
|
||||||
| filesystemtable | 记录所用的文件系统 |
|
|
||||||
| filesystem_operation_table | 记录操作函数如何实现（如open，close……）|
|
|
||||||
|相关锁 | 如fd的互斥锁等 |
|
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
### FAL (搭配SFUD驱动使用)
|
|
||||||
#### SFUD
|
|
||||||
**[SFUD](https://github.com/armink/SFUD)**：(Serial Flash Universal Driver) 串行 **Flash 通用驱动库**，如：sfud_get_device（）、sfud_read（）、sfud_erase（）、sfud_write（）等函数接口帮助我们能够**实现对不同Flash的读写**。
|
|
||||||
#### FAL
|
|
||||||
**Fal组件**：(Flash Abstraction Layer) Flash 抽象层
|
|
||||||
调用SFUD，**将Flash分区，创建块设备**，文件系统要在块设备上搭建
|
|
||||||
[FAL 框架图](https://www.rt-thread.org/document/site/#/rt-thread-version/rt-thread-standard/programming-manual/fal/fal)
|
|
||||||
#### FAL API
|
|
||||||
[**FAL API详细链接**](https://www.rt-thread.org/document/site/#/rt-thread-version/rt-thread-standard/programming-manual/fal/fal_api)
|
|
||||||
|
|
||||||
#### FAL 初始化流程
|
|
||||||
W25Q64→注册为spi20设备，挂载到spi2总线上（**SPI设备**）→*通过SFUD驱动*`rt_sfud_flash_probe()`→跟一个命名为"W25Q64"的SPI_FLASH设备进行绑定(**SPI_FLASH设备**)→*通过FAL抽象层*→对SPI_FLASH设备进行分区，将对应分区注册为BLK（块）设备（**BLK设备**）→对BLK设备格式化
|
|
||||||
|
|
||||||
**分区表**
|
|
||||||
|
|
||||||
| （不用管） | 分区名称 | 位置 | 偏移量 | 大小 |
|

|
|

||||||
|
|
||||||
### DFS结合FAL配置W25Q64
|
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
## 我的实践
|
|
||||||
### 读取传感器数据，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
