micropython _thread -多线程用法

import _thread

import utime

import urandom

gLock = None

# 线程1处理函数

def th(name):

    while True:

        # 休眠随机时间

        utime.sleep(urandom.random())

        # 等待获取互斥锁

        gLock.acquire()

        # 打印当前系统时间

        print(name, "lock acquired at ", utime.ticks_ms())

        # 休眠随机时间

        utime.sleep(urandom.random())

        # 释放互斥锁

        gLock.release()

if __name__ == '__main__':

    #创建互斥锁

    gLock = _thread.allocate_lock()

    # 获得互斥锁

    gLock.acquire()

    # 创建线程1

    _thread.start_new_thread(th, ["th1"])

    # 创建线程2

    _thread.start_new_thread(th, ["th2"])

    # 休眠1秒

    utime.sleep(1)

    # 释放互斥锁

    gLock.release()

    while True:

        utime.sleep(1)
