Cli模块

描述：Cli模块主要用于处理Cli命令，并根据命令显示系统状态或系统配置参数修改。

src/main/cli/
├── cli.c
├── cli_debug_print.h
├── cli.h
├── settings.c
└── settings.h0 directories, 5 files

注：该模块主要支持BetaFlight模块设计之二：SERIAL任务分析。

Cli接口

extern bool cliMode;                             //判断系统处于Cli模式void cliProcess(void);                           //处理Cli命令
void cliEnter(struct serialPort_s *serialPort);  //进入Cli模式
bool resetConfigToCustomDefaults(void);          //支持命令行“defaults”命令
bool hasCustomDefaults(void);                    //支持命令行“defaults”命令

Cli框架

cliMode：判断当前Cli模块状态(TRUE为Cli模式；反之则不在该模式)
cliEnter：触发Cli模块进入工作模式
cliProcess：处理Cli命令
cliExit：“CTRL + D”，退出Cli模式 //这个命令是内嵌在CliProcess函数内部

Cli命令结构

一个Cli命令通过name(命令名字)，description(命令描述)，args(命令参数表)，cliCommand(命令函数)组成。

typedef void cliCommandFn(const char* name, char *cmdline);typedef struct {const char *name;
#ifndef MINIMAL_CLIconst char *description;const char *args;
#endifcliCommandFn *cliCommand;
} clicmd_t;

例如：help命令

CLI_COMMAND_DEF("help", "display command help", "[search string]", cliHelp),

主要函数分析

cliProcess函数

cliProcess├──> <!cliWriter>  //Cli模式下处理自定义命令或者尚未进入Cli模式，直接返回│   └──> return├──> cliWriterFlush();└──> <serialRxBytesWaiting(cliPort)>  //非阻塞式数据等待├──> c = serialRead(cliPort);└──> processCharacterInteractive(c); //交互式串口字节处理

processCharacterInteractive函数

processCharacterInteractive├──> <c == '\t' || c == '?'> //实际在配置软件里面tab可以，?无法使用│   ├──> [遍历cmdTable，匹配相近的命令(pstart, pend)]│   ├──> [如果只有一个命令，尝试补全命令]│   └──> [如果多个匹配命令，反馈命令列表]├──> <!bufferIndex && c == 4> // CTRL-D│   ├──> cliExit("", cliBuffer); //退出Cli模式│   └──> return├──> <c == 12>  // NewPage(CTRL-L) 清屏│   ├──> cliPrint("\033[2J\033[1;1H");│   └──> cliPrompt();├──> <c == 127><bufferIndex>  //回退一个字符│   ├──> cliBuffer[--bufferIndex] = 0;│   └──> cliPrint("\010 \010");└──> <other scenarios>└──> processCharacter(c);

注：ASCII表，详见链接

processCharacter函数

processCharacter├──> <bufferIndex && (c == '\n' || c == '\r')>│   ├──> cliPrintLinefeed();│   ├──> <processingCustomDefaults>  //定制命令处理场景，配合cliPrompt打印│   │   └──> cliPrint("d: ");│   ├──> [Strip comment starting with # from line]  //注释行屏蔽│   ├──> [Strip trailing whitespace] //尾部空格屏蔽│   ├──> <bufferIndex > 0)>  // Process non-empty lines│   │   ├──> [遍历列表寻找命令index]│   │   └──> [执行index命令指定的命令函数执行，异常反馈错误类型]│   ├──> memset(cliBuffer, 0, sizeof(cliBuffer));│   ├──> <!cliMode>│   │   └──> return;│   └──> cliPrompt();└──> <bufferIndex < sizeof(cliBuffer) && c >= 32 && c <= 126>├──> <!bufferIndex && c == ' '>│   └──> return // 最前面的空格忽略，直接丢弃├──> cliBuffer[bufferIndex++] = c;  //符合条件的字符保存下来，供后续处理使用└──> cliWrite(c);
