任务调用示例

 RTX 51 TNY 可做多任务调度，API较为简单。

/*　接口API　*/

//　创建任务
extern unsigned char os_create_task     (unsigned char task_id);
//　结束任务
extern unsigned char os_delete_task     (unsigned char task_id);

//　等待
extern unsigned char os_wait            (unsigned char typ, 
                                         unsigned char ticks,
                                         unsigned int dummy);
extern unsigned char os_wait1           (unsigned char typ);

extern unsigned char os_wait2           (unsigned char typ,
                                         unsigned char ticks);
//　发送信号
extern unsigned char os_send_signal     (unsigned char task_id);
extern unsigned char os_clear_signal    (unsigned char task_id);




/*　用法　*/

void task_led() _task_ 任务代码{
    
}


void task_main() _task_ 任务代号{

    //开启子任务
    os_create_task(task_led); 

    // 结束入口任务
    os_delete_task(task_main);

}

通过分析电路可知

• 引脚为P05和P34
• 当引脚为高电平时，行成电时差，LED会被点亮

编程思路

• Driver中创建LED.c文件
• Driver中创建LED.h文件
• User中main.c文件为程序入口，编写子任务函数后在task_main中进行调用
