c51接收部分一接收像死机了一样！ [复制链接]

c51接收部分一接收像死机了一样！我在串口助手中发送的数据为：０２０００１０２
节点号为2,
一发送本来显示的界面为：
１.输入开始
２.节点设置
请选择：
可是一发送，在第0行0列显示请选择＊
按键也没有反应，像列了一样？郁闷死了？

这个红色的语句，判断的结果永远是true？

menglin

不会的，这个只是当在输入工单号是时按了d健就不能按数字了，没问题的现在是把发部分去掉，就可以接收了，把接收不部分去掉，发送也ok'俩个并存就用问题了

huanglx

有收有发的情况，可以先用查询来实现。

接收我就是用查寻的发法啊，在main中的啊，看到了吗？
