# 软件包机制
## pkg —upgrade
从软件包索引仓库拉取到本地仓库，更新软件包索引
解决找不到软件包的问题
也可以去env package文件夹git 拉取

llm chat软件包
通过api，在单片机在上使用大模型ai

配置步骤
api key 获取 https://bailian.console.aliyun.com/?tab=model#/model-market

## Kconfig
配置文件

![screenshot_image.png](https://oss-club.rt-thread.org/uploads/20250801/fa148b5a73b6fc50ae3785eb9789897f.png)

在c语言 宏 + 条件编译
可以分布在各个文件夹
https://www.rt-thread.org/document/site/#/development-tools/build-config-system/Kconfig
selete 使用要慎重，否则关不掉
shift+?可以查看该配置项情况

上手尝试：对应Kconfig
```
menu "Onboard Peripheral Drivers"                    
    menuconfig BSP_MQTT_MESSAGE
        bool "Enable MQTT default message"
        default n
        if BSP_MQTT_MESSAGE
            config BSP_MQTT_MESSAGE_NAME
                string "name"
                default "abc"
            config BSP_MQTT_MESSAGE_STUDY
                string "study"
                default "abd"
        endif
```

# 省略……
endmenu
注意不要手动改rtconfig.h的配置，否则env更新会失效
## env
上位机，环境变量、软件包
## scons
构建工具

```
SConstruct SCons 入口脚本
scons —dist 打包
scons -c 清理
scons —verbose 详细信息
```

keil来开发要注意rtconfig.py的EXEX_PATH是否正确
函数

```python
import os
from building import *
cwd = GetCurrentDir() # 获取当前地址
objs = [] # 定义一个空列表，用于存储所有的对象文件
list = os.listdir(cwd) # 获取目录
src  = Glob('*.c') # 所有.c文件
CPPPATH = [cwd] # 包含路径
if not GetDepend('BSP_DRV_EMAC'):
    SrcRemove(src, ['drv_smc911x.c'])
if not GetDepend('BSP_DRV_CLCD'):
    SrcRemove(src, ['drv_clcd.c'])
if not GetDepend('RT_USING_SERIAL_V1'):
    SrcRemove(src, ['drv_uart.c'])
if not GetDepend('RT_USING_SERIAL_V2'):
    SrcRemove(src, ['drv_uart_v2.c'])
group = DefineGroup('Drivers', src, depend = [''], CPPPATH = CPPPATH) # 名字，.c, 依赖的宏，.h
# 有SConscript就追加
for d in list:
    path = os.path.join(cwd, d)
    if os.path.isfile(os.path.join(path, 'SConscript')):
        objs = objs + SConscript(os.path.join(d, 'SConscript'))
objs = objs + group
Return('objs')
```

### 网络组件
ntp 获取时间和 检查网络情况

## 软件包
## kawaii mqtt

注意mqtt client id 随便起不要一样

![screenshot_image.png](https://oss-club.rt-thread.org/uploads/20250801/92d2c4722ef9444db52e9e419933080d.png.webp)
在MQTTX相应配置，还是注意mqtt client id 随便起不要一样的

![screenshot_image.png](https://oss-club.rt-thread.org/uploads/20250801/92d2c4722ef9444db52e9e419933080d.png.webp)
动手实践
在Kconfig加入上文的代码
修改mqtt demo 实现发送json

```c
char *tmp_json ;
char *message_json(void)
{
    cJSON* root = cJSON_CreateObject();
    cJSON_AddStringToObject(root, "name", BSP_MQTT_MESSAGE_NAME);
    cJSON_AddStringToObject(root, "study", BSP_MQTT_MESSAGE_STUDY);
    tmp_json = cJSON_Print(root);
    rt_kprintf("json:%s\n",tmp_json);
    cJSON_Delete(root);
    return tmp_json;
}
MSH_CMD_EXPORT(message_json,print json message);
static int my_mqtt_publish_handle(mqtt_client_t *client)
{
    mqtt_message_t msg;
    memset(&msg, 0, sizeof(msg));
    msg.qos = QOS0;
    msg.payload = (void *)message_json();
    return mqtt_publish(client, KAWAII_MQTT_PUBTOPIC, &msg);
}
```
