在设计ADAU1452开发板时，如何选型配套MCU？（STM32系列，有无相关推荐？） +1
Answered

你好，我正在设计一款ADAU1452开发板，我想使用MCU完成板上控制和对DSP的控制/通信与烧录，对于MCU选型是否有推荐？若选择STM32系列，是否有较好的硬件配置教程？

JTAG 上挂了不同型号的DSP 0
Not Answered

在我们的音频处理器项目中，使用了多个DSP,有一个ADSP-BF516和一个ADSP-21488，它们通过串联的方式都连接在JTAG链路上。在VisualDSP++ 开发环境中进行ADSP-BF516仿真的时候，新建Session时，只能选两个相同型号的DSP,我选择的是ADSP-BF516。在Connect to Target时经常出错，很少能联接成功。可有解决方法?

adau1701 使用Surround Sound Volume Control，如何通过坐标计算出要写入的reg数值？ +1
Answered

这个组件，在set position时候不产生i2c数据，要拖动才行，不能精确设置位置，请问下是否有对应的计算方法，把xy坐标，换算成reg数值或者有大表来查表也可以

Answered

芯片手册 www.analog.com/.../ad2426-ad2427-ad2428.pdf 中有描述说上下行分别支持最多32通道的音频传输：在参考手册 www.analog.com/.../ad242x-trm.pdf 的 Table3-5: Bandwidth Examples 表中记录的最大数分别是 51 和 34。但是我按照这个表在 Sigma Studio 4.7 中配置时，提示甚至，我只是配置下行发送 28通道，24bit 的数据，也会提示错误：所以，我不清楚...

如何提升ADSP_21565 FIR处理速度 +1

这个图表在ee-408的第6页在ee-408这个关于FIR的手册中给定的性能测试是说2156x系列64抽头系数处理对应窗口大小所用的时间，其中窗口大小为1024时的时间为33us，而我通过示波器测量抽头系数64，窗口大小1024，所用时间却是470us!想知道是那出现了问题。我是根据给定的参考步骤来完成的，这段文字在ee-408的16页
