做TAS3308的音效项目，I2C地址分配高于222时程序就不能用I2C配置了，为什么？

问答对人有帮助，内容完整，我也想知道答案 0 你好，我在做TAS3308的音效项目的时候，当我的I2C地址分配高于222时，发现下载到EVM板上的程序就不能用I2C配置了。I2C映射的coef和实际的参数就对不上号了。但是如果下面的地址表，我去掉一个component，减少两个I2C的地址。就好了。这可能是什么问题呢？请帮忙提点调试建议啊。当错误代码down下去后，对32的I2C地址写 ‘00 00 02 02’; Line IN->PWM1口就会有声音发出了。而我程序中的好多参数调整对输出都不起作用。地址表如下。 Application: PurePath Studio Graphical Development Environment File Name: me.addr Date: 2014-12-26 14:46:12 Version: 1.88 build 5 ================================================================================ # 0 4 !

答案对人有帮助，有参考价值 0 你好，根据你的描述，这个问题可能是由于I2C地址冲突或者地址分配不当导致的。以下是一些建议和可能的原因： 1. I2C地址冲突：当你的I2C地址分配高于222时，可能与其他设备或者模块的地址冲突，导致I2C通信失败。请检查你的系统中是否有其他设备使用相同的I2C地址，并尝试更改地址以避免冲突。 2. I2C地址分配不当：确保你的I2C地址分配是正确的，并且遵循TAS3308的规格。如果地址分配不当，可能会导致I2C通信失败或者参数映射错误。 3. 检查I2C通信线路：检查I2C通信线路是否正确连接，包括数据线（SDA）和时钟线（SCL）。确保线路没有短路、断路或者接触不良的问题。 4. 检查电源和地线：确保I2C设备的电源和地线连接正确，没有短路或者断路的问题。 5. 检查程序代码：检查你的程序代码，确保I2C通信和参数设置是正确的。特别是地址表和参数映射部分，确保它们与TAS3308的规格一致。 6. 使用调试工具：使用I2C调试工具（如逻辑分析仪）来监控I2C通信，检查通信过程中是否有错误或者异常。 7. 减少I2C地址：如果问题仍然存在，可以尝试减少I2C地址的数量，以减少地址冲突的可能性。 8. 参考文档：查阅TAS3308的官方文档，了解其I2C通信和地址分配的详细信息，以确保你的设置是正确的。希望这些建议能帮助你解决问题。如果问题仍然存在，请提供更多详细信息，以便进一步分析和解决。
