#### 移植
- 移植十分简单,只需要在初始化的时候提供字符输入输出函数即可
```C
/* 例如移植到linux平台 */
int cmd_get_char(uint8_t *ch)
{
*ch = getch();
return 1;
}
int cmd_put_char(uint8_t ch)
{
putchar(ch);
return 1;
}
int main(void)
{
/*调用初始化函数的时候传入字符输入输出函数*/
xcmder_t* cmder = xcmd_create_default(cmd_get_char, cmd_put_char);
if(cmder)
{
/* 初始化默认的一些快捷键 */
default_keys_init(cmder);
/* 初始化默认的一些命令 */
default_cmds_init(cmder);
/* 手动调用显示log的命令 */
xcmd_exec(cmder, "logo");
while(1)
{
/* 主任务 */
xcmd_task(cmder);
}
}
return 1;
}
```

#### 使用说明

##### 注册自定义命令
```C
static void cmd_print(int argc, char* argv[])
{
if(param_check(1, argc, argv))
{
printf("%s\r\n", argv[1]);
}
}
static void cmd_example(int argc, char* argv[])
{
uint8_t i;
if(param_check(1, argc, argv))
{
if(strcmp(argv[1], "str") == 0)
{
for(i=2; i<argc; i++)
{
printf("%s\r\n", argv[i]);
}
}
if(strcmp(argv[1], "int") == 0)
{
for(i=2; i<argc; i++)
{
printf("%d\r\n", atoi(argv[i]));
}
}
if(strcmp(argv[1], "float") == 0)
{
for(i=2; i<argc; i++)
{
printf("%f\r\n", atof(argv[i]));
}
}
}
}
static xcmd_t cmds[] =
{
{"print", cmd_print, "print anything", NULL},
{"example", cmd_example, "example [-f|-i|-s] [val]", NULL},
};
void test_cmd_init(xcmder_t *cmder)
{
xcmd_register(cmder, cmds, sizeof(cmds)/sizeof(xcmd_t));
}
```
##### 注册自定义快捷键
```C
int cmd_ctr_a(void* pv)
{
printf("this is ctr+a\n");
}
int cmd_ctr_c(void* pv)
{
exit(0);
}
static xcmd_key_t user_keys[] =
{
{CTR_A, cmd_ctr_a, NULL},
{CTR_C, cmd_ctr_c, NULL},
};
void test_keys_init(xcmder_t *cmder)
{
xcmd_key_register(cmder, user_keys, sizeof(user_keys)/sizeof(xcmd_key_t));
}
```
