Contiki-NG中shell使用

    给项目添加shell

    只需要在项目的Makefile里添加如下代码即可:

    MODULES += $(CONTIKI_NG_SERVICES_DIR)/shell
    

    $(CONTIKI_NG_SERVICES_DIR)所指的目录就是contiki-ng/os/services

    通过串口和板子相连就可以使用shell了

    #0012:4b00:192e:4337>
    

    使用help命令,可以看到shell提供的所有指令帮助信息

    #0012.4b00.192e.4337> help
    Available commands:
    '> help': Shows this help
    '> reboot': Reboot the board by watchdog_reboot()
    '> log module level': Sets log level (0--4) for a given module (or "all"). For m
    odule "mac", level 4 also enables per-slot logging.
    '> mac-addr': Shows the node's MAC address
    '> ip-addr': Shows all IPv6 addresses
    '> ip-nbr': Shows all IPv6 neighbors
    '> ping addr': Pings the IPv6 address 'addr'
    '> routes': Shows the route entries
    '> rpl-set-root 0/1 [prefix]': Sets node as root (1) or not (0). A /64 prefix ca
    n be optionally specified.                                                      
    '> rpl-local-repair': Triggers a RPL local repair                               
    '> rpl-refresh-routes': Refreshes all routes through a DTSN increment           
    '> rpl-status': Shows a summary of the current RPL state                        
    '> rpl-nbr': Shows the RPL neighbor table                                       
    '> rpl-global-repair': Triggers a RPL global repair 
    

    可以试一下其中的命令,比如:

    #0012.4b00.192e.4337> ip-addr                                                   
    Node IPv6 addresses:                                                            
    -- fd00::212:4b00:192e:4337                                                     
    -- fe80::212:4b00:192e:4337 
    

    定制shell命令

    Contiki-ng/os/services目录里的shell-commands.c文件中,找到:

    const struct shell_command_t builtin_shell_commands[]
    

    按照代码里现有的命令的样子,定制自己的shell命令,比如添加如下代码:

    { "config",      cmd_hello,     "'> hello': Just say hello." },
    

    然后,添加命令的实现代码,在同一个文件中:

    static
    PT_THREAD(cmd_hello(struct pt *pt, shell_output_func output, char *args))
    {
      PT_BEGIN(pt);
    
      SHELL_OUTPUT(output, "Hello, world!\n");
    
      PT_END(pt);
    }
    

    重新编译即可。

    #0012.4b00.192e.4337> hello                                                
    Hello, world!
