有用STC51解码Keeloq（hcs301）的吗？

fsmcu 发表于 2015-3-18 15:46:51

以前用51做过，网上很容易下载到这种代码

要不你提供一个，我找到了pic 的但是对pic的不熟悉

51_KEELOQ_HCS301 现在常用的都是PIC解滚码 0/301，及那个DECRYPT的加密算法很少能找到这样的C程 SCM 单片机开发 210万源代码下载- www.pudn.com
http://www.pudn.com/downloads194/sourcecode/embed/detail912953.html 这里有个谁可以下载吗

你说的是这个吗？

你的莫元为什么是负的。。。

这个好像是的没有验证，不知打坛友们有没有实际验证过的

这个有实验好用么？少文件吧！

只是被扣了而已呵呵

官方说用他们的代码智能用PIC的单片机。

qxc16b 发表于 2015-8-4 14:51:44

我用过51的解Keeloq码，51会干扰无线接收板，能解码但接收距离会很近，用PIC的就很好。

这个不错，下来学习。
