# xcmd
|
||||
|
||||
#### 效果展示
|
||||
|
||||
|
||||
|
||||
#### 介绍
|
||||
|
||||
xcmd是一款单片机命令行工具，移植十分方便，并且对flash与ram占用很小，旨在为单片机提供一个能够快速搭建且占用资源很小的命令行工具，可以大大加快单片机程序调试工作，它有一下几个优点。
|
||||
|
||||
1. **移植十分简单**
|
||||
2. **资源占用约8K rom 1K ram**
|
||||
2. **资源占用很小**
|
||||
3. **支持历史记录**
|
||||
4. **支持命令自动补全**
|
||||
5. **支持注册快捷键**
|
||||
5. **支持`xcmd_cmd_register()/xcmd_key_register`方法注册命令或按键**
|
||||
5. **支持`XCMD_EXPORT_CMD()/XCMD_EXPORT_KEY()`方法直接导出命令或按键，不需要额外运行注册函数**
|
||||
6. **支持 `xcmd_cmd_register()/xcmd_key_register`方法注册命令或按键**
|
||||
7. **支持 `XCMD_EXPORT_CMD()/XCMD_EXPORT_KEY()`方法直接导出命令或按键，不需要额外运行注册函数**
|
||||
|
||||
#### 支持的平台
|
||||
|
||||
1. linux
|
||||
2. arduino
|
||||
3. stm32
|
||||
4. esp32
|
||||
5. qemu-stm32
|
||||
|
||||
#### 测试过的串口软件
|
||||
|
||||
2. （win/linux推荐）putty
|
||||
3. （win推荐）MobaXterm
|
||||
5. （linux端推荐）cu
|
||||
1. SecureCRT：请设置成Xterm模式
|
||||
4. Xshell
|
||||
6. nc(支持性很差)
|
||||
7. minicom(支持性很差)

7. nc(支持性很差)
|
||||
8. minicom(支持性很差)
|
||||
|
||||
#### 支持的扩展功能
|
||||
|
||||
1. 类linux风格的快捷键：ctr+left、ctr+right、ctr+a、ctr+e、ctr+u、ctr+k、ctr+l快捷键
|
||||
2. 支持字体、背景颜色显示
|
||||
3. 支持类linux的文件操作（Fatfs文件系统）：ls、cd、rm、df、mv、mkdir、touch、read、write
|
||||
3. 支持类linux的文件操作（Fatfs文件系统）：ls、cd、rm、df、mv、mkdir、touch、rd、wr、cat
|
||||
4. 支持基于socket的udp server、udp client测试程序
|
||||
|
||||
#### 移植
|
||||
|
||||
- 移植十分简单，可在example中查看各平台移植结果
|
||||
|
||||
1. 在初始化的时候提供字符输入输出函数即可
|
||||
2. 从example中拷贝一个xcmd_confg.h到自己的项目
|
||||
|
||||

||||

||||
|

#### 配置
|
||||
|
||||
配置xcmd_config.h
|
||||
|

**注意**： 如果不知道如何修改连接脚本，建议不要使能ENABLE_XCMD_EXPORT。不使能ENABLE_XCMD_EXPORT的情况下有更好的兼容性移植更加简单
