VxWorks多任务编程示例与技术解答

该示例展示了在VxWorks实时操作系统中进行多任务编程的方法。通过创建多个任务并进行任务间通信，展示了如何利用VxWorks的任务管理器和消息队列实现并发处理和数据共享。

#include <vxWorks.h>
#include <taskLib.h>
#include <msgQLib.h>
#include <stdio.h>

#define MSG_SIZE 50
#define MAX_MSGS 10

MSG_Q_ID msgQId;

void task1() {
    char msg[MSG_SIZE] = "Message from Task 1";
    while(1) {
        msgQSend(msgQId, msg, MSG_SIZE, WAIT_FOREVER, MSG_PRI_NORMAL);
        taskDelay(100);
    }
}

void task2() {
    char receivedMsg[MSG_SIZE];
    while(1) {
        msgQReceive(msgQId, receivedMsg, MSG_SIZE, WAIT_FOREVER);
        printf("Received: %s\n", receivedMsg);
    }
}

void vxWorksDemo() {
    msgQId = msgQCreate(MAX_MSGS, MSG_SIZE, MSG_Q_FIFO);
    taskSpawn("task1", 100, 0, 2000, (FUNCPTR)task1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0);
    taskSpawn("task2", 100, 0, 2000, (FUNCPTR)task2, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0);
}
