main.c

我移植的uCos 2.52版本,在MCS51上运行,代码进行了一些优化,可以编译在小模式.

#include <includes.h>
//#include "serial.h"
#define MaxStkSize              64    /*每个任务使用同样大小的堆栈，这就是每个堆栈的大小*/

OS_STK _XDATA TaskStartStk[OS_MAX_TASKS][MaxStkSize];

void Task1(void _XDATA *nouse) reentrant;
void Task2(void _XDATA *nouse) reentrant;

void main(void)
{
    OSInit();
    
//    InitHardware();
#if OS_STK_GROWTH == 1
    OSTaskCreate(Task1, (void *)0, &(TaskStartStk[0][MaxStkSize-1]),2);
    OSTaskCreate(Task2, (void *)0, &(TaskStartStk[1][MaxStkSize-1]),3);
#else 
	OSTaskCreate(Task1, (void *)0, &(TaskStartStk[0][0]),2);
    OSTaskCreate(Task2, (void *)0, &(TaskStartStk[1][0]),3);
#endif
    OSStart();
}


void Task1(void _XDATA *nouse) reentrant
{
    nouse=nouse;
	TMOD&=0xF0;
	TMOD|=0x01;
    ET0=1;  //开时钟节拍中断
	TR0=1;
    for(;;)
    {
        //SendPCCmd("A1",2);
        OSTimeDly(OS_TICKS_PER_SEC);
    }    
}

void Task2(void _XDATA *nouse) reentrant
{
    nouse=nouse;
    for(;;)
    {
        //SendPCCmd("B2",2);
        OSTimeDly(OS_TICKS_PER_SEC*6);
    }
}
