【Follow me第二季第3期】进阶任务：示例程序中新增命令打印信息

 本次任务是进阶任务：示例程序中新增命令打印信息。

 在memu_main.c中修改s_menu_items菜单数组。添加，Hello Information，对应函数为hello_display_menu。

/* Table of menu functions */
static st_menu_fn_tbl_t s_menu_items[] =
{
    {"Hello Information"                       , hello_display_menu},
    {"Kit Information"                         , kis_display_menu},
    {"Web Server"                              , eth_emb_display_menu},
    {"Network Name Lookup"                     , eth_www_display_menu},
    {"Quad-SPI and Octo-SPI Speed Comparison"  , ext_display_menu},
    {"Cryptography and USB High speed (MSC)"   , enc_display_menu},
    {"Next Steps", ns_display_menu },
    {"", NULL }
};

然后//memu_kis.c文件中新增以下代码

//memu_kis.c
#define HELLO_OPTIONS     "\r\n\x1b[2m\x1b[37m a) FollowMe 2-3 "                                                         \
                        "\r\n\x1b[2m\x1b[37m a) Kit name:                           %s "                               \
                        "\r\n\x1b[2m\x1b[37m b) Kit ordering part number:           %s "                               \

编译，下载运行。

可以看到，新增的Eeworld and Dgikey is very good和fellow Me 2-3字样，新增命令成功。
