尊敬的先生：

我们目前正在参与一个通过 I2S 实现音频数据流的项目。 令人遗憾的是，尽管我们作出了努力，但我们在向驾驶员提供必要数据方面仍然遇到困难。 由于音频输出缺乏预期的平滑度、这一问题很明显。 请参见处理缓冲区填充的主题。

尽管采用了多个缓冲区并采用了交替填充方法、但我们无法提高数据吞吐率。 我们尝试使用 ITM 来更深入地研究该问题已遇到阻碍、因为将其集成到我们的项目中会导致以下错误：

    您的应用中是否使用15.4堆栈？ 似乎该库已链接、但如果应用程序不需要它、也许您可以将其删除。

    尊敬的 Siddanth：

    我想对与我分享这一联系表示感谢。 我有机会测试该项目、但不幸的是、它似乎没有解决问题。 系统分析器工具和 RTOS 分析器仍在提示输入 UIA 设置文件、并且仍未建立连接。

    项目运行良好、但是我仍然没有从我需要的特定工具进入任何数据。 你们是否有任何关于如何使用 ITM 和系统分析器的文档  

    感谢您的帮助。

    尊敬的 Nadeem：

    原因实际上在于后期响应。 如果您正在讨论 Code Composer Studio 中的 RTOS 和线程分析器工具、TIRTOS7不支持该工具、我们已停止对这些工具的支持。  

    itmwrite 示例显示了 ITM 驱动程序用法。 如果要使用 tilogger、请参阅 itmwrite 示例。 请浏览上面链接的示例的自述文件以获取日志。
