RT-Thread通过邮箱两个线程通过产生随机数进行通信并给出运行结果

很抱歉,我是一个语言模型AI,没有具体的运行环境,无法为您提供RT-Thread的运行结果。但是,我可以给您提供以下代码作为参考:
```
#include <rtthread.h>
#include <stdlib.h>
#define MAILBOX_SIZE 4
static rt_mailbox_t mailbox;
static void thread1_entry(void* parameter)
{
rt_uint32_t rand_num;
while (1) {
rand_num = rand(); // 产生随机数
rt_mb_send(&mailbox, rand_num); // 发送随机数到邮箱
rt_thread_delay(1000); // 线程1延时1秒
}
}
static void thread2_entry(void* parameter)
{
rt_uint32_t recv_num;
while (1) {
rt_mb_recv(&mailbox, &recv_num, RT_WAITING_FOREVER); // 从邮箱中接收随机数
rt_kprintf("Received Number: %d\n", recv_num); // 打印接收到的随机数
}
}
int main(void)
{
rt_thread_t thread1, thread2;
rt_err_t result;
mailbox = rt_mb_create("mailbox", MAILBOX_SIZE, RT_IPC_FLAG_FIFO); // 创建邮箱
thread1 = rt_thread_create("thread1", thread1_entry, RT_NULL, 1024, 8, 10); // 创建线程1
if (thread1 != RT_NULL) {
rt_thread_startup(thread1);
}
thread2 = rt_thread_create("thread2", thread2_entry, RT_NULL, 1024, 8, 10); // 创建线程2
if (thread2 != RT_NULL) {
rt_thread_startup(thread2);
}
result = rt_thread_join(thread1); // 等待线程1结束
if (result == RT_EOK) {
rt_kprintf("Thread1 has finished!\n");
}
result = rt_thread_join(thread2); // 等待线程2结束
if (result == RT_EOK) {
rt_kprintf("Thread2 has finished!\n");
}
rt_mb_delete(mailbox); // 删除邮箱
return 0;
}
```
以上代码中,我们创建了一个名为`mailbox`的邮箱,两个线程分别为`thread1`和`thread2`。线程1每隔1秒钟产生一个随机数,并将其发送到邮箱中;线程2则从邮箱中接收随机数,并打印出来。在主函数中,我们等待线程1和线程2结束后,删除邮箱。
