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
