TAS3308的I2C地址问题

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。

嗯, 看来地址是有些限制, 不能随便设置

这个问题好像是处在内存不够上。不是I2C地址不够。因为我们删除掉一些component后发现可以正常运行。只是编译器没有提示内存溢出。

所以想请问一个问题。coef和databuffer除了component的I2C映射了的之外，是不是还需要保留一部分给component本身的运行，这个比例大约需要多少？
