在淘宝上看见你买433发射接收一体模块的评论。
请问这个一体模块可以学习已有的遥控器按键值吗?
即:

unsigned char up[7] = {0xfd,0x03,0x1a,0xd9,0x11,0x36,0xdf};

这是怎么来的?

这个店家不是同时卖解码模块吗?我是买的那种收发做用一个串口上的,按键之后接收模块就可以看到码值了,看他的接收模块的介绍

@IoTServ 谢谢回复。
因为我只玩过一点树莓派、8266。没玩过这种射频信号,缺乏一些背景知识,比如这些是明码,广播接收可得,还是有加密的。
我想问的就是买一个一体模块,就能完成 1.学习获得遥控器信号数据 2.控制发射信号,不需要另外用解码模块解码?
或者说,是不是你本来有一个普通车库门和遥控器,拿一体模块就能获得遥控器数据然后自己改造了。

如果哪里有经验、资料分享也请指点一下,不胜感激。主要缺乏背景知识,软件我可以自己找资料,但是硬件不熟。

你去看人家的模块的介绍,这个大部分315或者433(二选其一)都可以学习的,这个就是接收发射编解码模块,直接在电脑上也能用(使用usb转ttl连接),你说的那些都支持
