STM32L475VET RT-Thread 多线程编程实例

以下是一个基于STM32L475VET的RT-Thread多线程程序示例：

#include <rtthread.h>
#include <stdio.h>

#define THREAD_STACK_SIZE   512
#define THREAD_PRIORITY     10

static rt_thread_t thread1 = RT_NULL;
static rt_thread_t thread2 = RT_NULL;

static char thread1_stack[THREAD_STACK_SIZE];
static char thread2_stack[THREAD_STACK_SIZE];

static void thread1_entry(void* parameter)
{
    while (1)
    {
        rt_kprintf('Thread 1 is running\n');
        rt_thread_mdelay(1000);
    }
}

static void thread2_entry(void* parameter)
{
    while (1)
    {
        rt_kprintf('Thread 2 is running\n');
        rt_thread_mdelay(2000);
    }
}

int main(void)
{
    rt_thread_init(&thread1, 'thread1', thread1_entry, RT_NULL,
                   &thread1_stack[0], sizeof(thread1_stack), THREAD_PRIORITY, 20);
    rt_thread_startup(&thread1);

    rt_thread_init(&thread2, 'thread2', thread2_entry, RT_NULL,
                   &thread2_stack[0], sizeof(thread2_stack), THREAD_PRIORITY, 20);
    rt_thread_startup(&thread2);

    return 0;
}

这个例子创建了两个线程'thread1'和'thread2'，并且它们分别打印出不同的消息。'thread1'每隔1秒打印一次消息，'thread2'每隔2秒打印一次消息。

请注意，以上代码仅为示例，实际开发时应根据具体需求进行修改和优化。还需要在RT-Thread配置中选择合适的编译器、配置目标板等。
