器件型号：CC1200
主题中讨论的其他部件：CC110L、 CC1000、 CC1101

您好！

我们开发了一个由基站和移动设备组成的无线生态系统。
基站正在使用 CC110L 收发器、而移动设备早已开发、仍然使用 CC1000。
由于难以获得 CC110L、我们被迫使用 CC1200收发器升级基站。

基站和移动设备之间使用的无线电数据协议非常简单、它使用固定大小的数据包、没有硬件 CRC、但遗憾的是使用曼彻斯特。我们无法更改它、因为它已被现场部署的移动设备使用。

按照 CC120x 用户指南第5.2章中的说明，我们能够成功地从 CC1000接收 CC1200上的数据包。

但是、无论是在 CC1000还是 CC110L 上、我们都无法正确接收来自 CC1200的数据包。请考虑、CC110L 作为接收器仅用于调试目的、因为它可以从 SmartRF Studio 进行管理。特别是对于 CC110L、我们仅接收40%到60%的数据包。

请在附件中找到用于 CC110L 的配置、该配置允许使用 CC1000正确的 TX/RX、以及仅允许使用正确 RX 的 CC1200配置。

要使用曼彻斯特与 CC1200进行传输并使用 CC110L 进行接收、您需要执行以下操作：

CC1200必须使用手动曼彻斯特编码的4字节同步字(因为 CC1200不会自动编码曼彻斯特同步)。

因此、CC110L 只能使用2字节同步字(编码后将为4字节)：

CC1101：0xD391

CC1200： 0xA65A9656 (0xD391曼彻斯特编码)

当在 CC110L 上仅使用一个2字节长同步字时、最好使用同步字的 CS 门控、以避免任何错误的同步检测：
