Excel 配置解析(excel_config.py):基于openpyxl实现 Excel 文件解析,提取外设名称、UDP 端口、协议类型、基地址等信息,存入DEVICE_CONFIG_DICT。
|
||||
'''
|
||||
'''
|
||||
### 核心功能说明
|
||||
1. **格式兼容**:支持解析Excel中**带逗号/空格的十六进制地址**(如`0x2080,0000`→`0x20800000`),自动清洗非十六进制字符。
|
||||
2. **列名容错**:兼容表头列名的**大小写、别名**(如“基地址”/“内存基地址”、“发送缓存”/“发送缓存区大小”)。
|
||||
3. **缺省值赋值**:未配置的项赋予合理默认值(如UDP端口默认8888、缓存大小默认512)。
|
||||
4. **合法性校验**:
|
||||
- 必须包含**名称、协议类型、内存基地址**核心列,否则解析失败;
|
||||
- 协议类型仅支持`UART/CAN/1553B/AD/OC`,非法协议直接跳过;
|
||||
- 外设名称为空的行直接跳过。
|
||||
5. **数据类型转换**:自动将十六进制地址转整数、端口/缓存大小转整数,转换失败友好提示并赋默认值。
|
||||
6. **日志记录**:全程打印解析日志(成功/失败/警告),便于问题排查。
|
||||
|
||||
### 配套Excel配置文件规范
|
||||
1. 保存为**xlsx格式**(兼容openpyxl解析,xls格式需额外安装xlrd);
|
||||
2. 表头至少包含:**名称、协议类型、内存基地址**,其他列可选;
|
||||
3. 协议类型填写:`UART/CAN/1553B/AD/OC`(大小写均可);
|
||||
4. 地址填写:十六进制格式(如`0x20800000`、`0x2080,0000`、`0x0000`);
|
||||
5. 端口/缓存大小填写**纯数字**。
|
||||
|
||||
### 简单测试
|
||||
在`config_files/`目录下创建`device_config.xlsx`,填入如下测试数据,直接运行该文件即可看到解析结果:
|
||||
|
||||
| 名称 | 协议类型 | 内存基地址 | 内存偏移地址 | UDP端口 | 说明 | 发送缓存区大小 | 接收缓存区大小 |
|
||||
|--------|----------|------------|--------------|---------|------------|----------------|----------------|
|
||||
| Uart0 | UART | 0x2080,0000 | 0x0000 | 8880 | 光纤陀螺A | 512 | 512 |
|
||||
| CAN1 | CAN | 0x20810000 | 0x0100 | 8881 | 姿态传感器 | 1024 | 1024 |
|
||||
| 1553B0 | 1553B | 0x20820000 | 0x0200 | 8882 | 测控模块 | 2048 | 2048 |
