Question

我已经注意到这段代码，我已经将它们放在一起进行测试如果任何EMI影响了我的输入。每次我启动我第一次运行这个脚本时会得到一个错误的假设。

        sleep(1)

我已将其追踪到 time.sleep ，导致此事发生。

是否有人经历过这种情况和/或有人可以尝试看看是否会在他们的设置上复制。

如果我在这段代码上评论 time.sleep ，那么误报就会停止发生。但是，我没有拖延，哈哈哈哈，

        print "pretime1"
        sleep(1)
        print "posttime1"

RPI python time.sleep导致GPIO上的错误事件检测
