The PurePath™ Wireless platform is a cost-effective and low-power solution optimized for wireless transmission of high-quality digital audio.
The CC85xx includes a robust built-in wireless audio transmission protocol and can control selected external audio devices. Utilizing numerous coexistence mechanisms allows the CC85xx to avoid interfering with, or being interfered by other 2.4 GHz radio systems.
The CC85xx operates autonomously, and can be used with or without an external MCU. An external host processor can be connected through SPI and control some aspects of its operation. The CC85xx interfaces easily with other TI audio ICs and DSPs (using I2S and DSP/TDM interfaces). More details can be found in the CC85xx Family User Guide.

PUREPATH-WL-CFG — PurePath™ 无线配置器
TI 交付的 CC85XX 器件未经编程，需要对固件进行编程才能在客户应用中运行。根据网络和应用角色（音频发送器、音频接收器等）、音频流传输方式以及应用电路设计等参数的不同，需要不同的固件。
PurePath 无线配置器 (PPWC) 是与 CC85XX 器件结合使用的图形 PC 工具，不需要额外的第三方工具。PPWC 使用经过预先编译的映像文件。根据用户的输入，PPWC 将安装这些文件的补丁程序以生成可下载的固件映像。然后设计人员能够通过 CC 调试器工具（内置于 CC85XXDK 中）直接从 PPWC 对 CC85XX 器件进行编程，或将其输出为 Intel (...)
