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 v1.3.0

CC85XX 器件在 TI 交付时没有经过编程，需要使用固件对其进行编程，以便在客户应用中正常运行。视具体参数需要使用不同的固件，这些参数中包括网络和应用角色（音频发射器、音频接收器等）、音频的流处理方式，以及应用电路设计。

PurePath 无线配置器 (PPWC) 是一种图形 PC 工具，用于配合 CC85XX 器件一起使用，不需要其他第三方工具。PPWC 使用预编译的图像文件。PPWC 根据用户的输入对这些文件进行修补，以生成可供下载的固件图像。设计人员随后即可通过 CC 调试器（包含在 CC85XXDK 中）从 PPWC 直接对 CC85XX 器件进行编程，或将其输出到 Intel (...)
