## CAMS DATU ：CAMS计算机辅助缝纫管理系统采集模块
|
||
|
||
#### 说明
|
||
|
||
- 待完成
|
||
|
||
RS232协议（未指定）
|
||
|
||
发送数据信息（未指定格式）
|
||
|
||
- 已完成
|
||
|
||
1.IO输入输出
|
||
|
||
2.flash读写，保存数据
|
||
|
||
3.USB串口动态配置信息（MQTT、Modbus等）
|
||
|
||
4.屏幕多级菜单显示IO数据、配置信息等
|
||
|
||
5.Modbus/485读写
|
||
|
||
7.ADC采集0-10V、3.3V、4-20ma（可配合硬件修改）
|
||
|
||
8.4G联网、MQTT连接
|
||
|
||
9.命令输出指定log用于调试
|
||
|
||
#### 开发环境
|
||
|
||
RT-Thread 软件打开 [点击下载](https://www.rt-thread.org/download.html#download-rt-thread-studio "点击下载")，版本: 2.2.7、C 语言
|
||
|
||
安装完成，**SDK下载RT-Thread 5.0.2与STM32F1固件库**，导入工程即可

| ----------- | ---------------- |
|
||
| driver | RT-Thread 的驱动 |
|
||
| libraries | rtt 内核 |
|
||
| linkscripts | 空间链接脚本 |
|
||
| packages | 第三方功能包 |
|
||
| rt-thread | rtt 内核 |
|
||
|
||
主要关心 application 目录下文件夹功能：
|
||
|
||
| 目录名 | 作用 |
|
||
| ------ | -------------------------------- |
|
||
| config | 用户配置功能 |
|
||
| fram | 读写flash，用以保存读取配置 |
|
||
| IO | 端口电平等 |
|
||
| OLED | 屏幕 |
|
||
| modbus | modbus 功能 |
|
||
| thread | 线程管理 |
|
||
| LTE | 网络配置 |
|
||
| ADC | ADC读值转换0-10V、3.3V、4-20ma等 |
|
||
| AIR820 | 4G模组与MQTT代码 |
|
||
| RS232 | 暂未定协议 |
|
||
|
||
由main函数为起始阅读点，读取配置后做初始化启动线程开始工作
|
||
|
||
main.c-> 读配置 ->thread.c -> IO
|
||
-> fram
|
||
-> modbus
|
||
-> .......
