51单片机解码PT2262出现问题
大家好，我的单片机负荷比较重，但必须接收PT2262信号，我设计如下程序，为什么不能接收到一串数据？在定时器1中断中判断同步码，接收到同步码之后，开启外部中断0，在外部中断0里面接收数据，可是最后都出现错误，通过串口发送出来的结果是j = 0；i = 0，dd = 1或2，很迷茫当中。
请教大家问题出在哪里？谢谢
程序如下：
sbit wireless_code_in = P3 ^ 2; // 无线信号接收端
/************************************************

我用来接收PT2262的程序ourdev_680089B7PNBK.rar(文件大小:817字节) (原文件名:pt2262.rar) 看不懂。。帮顶 如果是处理无线信号还是用其它的单片机比较好。 PT2262一直有干扰信号输出，不适合用中断来检波，最好是用主程序。51也可以做，如果是检不过来可能是你架构没有搭好哦 程序量大概有40几K，确实是忙不过来啊。 如果忙不过来的话！那直接用硬件解码就是了！ 我也很想知道办法。主要是干扰脉冲太多，确实不好处理。 顶下，为求通过 就被卡在了无线接收啊。 无线软件解码处理很头痛 我有个汇编的很好用
就是，51挺不好解码的，到现在也有弄好！哪位大侠给个有效的例程 搞错了，，dd 用单片机单一软解功能还行，多功能加软解码很不好弄，还是加一个硬解吧，除非你能合理的解决相关中断，干扰及各种功能程序的时序问题 软解码2262数据要求实时性很高 楼主还不如用PT2272 PT2262和PT2272本来就是一对儿，为什么要拆散人家？ 风雨无阻88 发表于 2015-10-18 16:18
