> ！！WARNING：目前版本的电机电流程序还支持DriverMaster采集的数据处理，等明确后，将不再支持，也即所有的电机电流数据（工业+协作），都是用诊断曲线来采集
v0.1.7.0(2024/06/29)
1. [openapi.py] 初步搭建起框架，完成了新老协议的封包/解包/异步采集日志的操作（未充分测试），其中解包操作未实现分帧的情况，因为暂无适应场景，也无测试实例，而且目前来看，不可能有消息超过文档中返回数据大小定义的上限（65535），故可以暂不做实现

> **关于HMI接口**
> - 封包解包顺序：帧长度二字节/包长度四字节/协议二字节/预留二字节，\x04\x00:\x00\x00\tR:\x02:\x00
> - 帧长度和包长度没有必然关系，单帧的时候是帧长度减去包长度等于6，包长度指的是所有内容的长度
> - HMI内部每次发送1024个字节，进行分包，内容长度规则是：第一帧1024-6=1018，第二帧（包含）及之后的帧，帧长度即是数据长度
