# Python Module: a2y_mew
a2y_mew 模块实现了扩展的`Mewtocol`通信协议。原始的`Mewtocol`来自 Panasonic，用于其 FP 系列 PLC 与上位机、触摸屏等设备通信。
本模块在以下方面对`Mewtocol`进行了扩展：
- 地址空间从 8 位整数扩展为不定长，最高可达 32 位。为了兼容性，最小为 8 位，在报文中至少占两个字节。
- 通讯方式从半双工增强为全双工，即主从双方可以同时发送数据。当从设备发生了某个事件（例如，输入点发生了变化），可以主动给主机发送报文。
## ChangeLog
- 2024-07-20 解决以下两个 bug，版本升级为 0.9.8：
- `MewMaster` 对象构建时缺乏 `timeout` 参数，导致 `close` 无限等待。
- `MewBase` 无法使用 `KCOM` 类型串口。
- 2024-07-08 修正依赖项，升级为 0.9.7
- 2024-06-22 使用`kcom`取代`hidcom`，版本升级为 0.9.6。
