您好

客户电路板当前安装了两个 PCM6260。 GPIO1已经连接到 GPIO 中断。 但无论您如何调整 bin 文件的寄存器设置值、都无法成功记录

    大家好、Gareth：

    客户是将两个器件的音频总线菊链在一起、还是单独配置这些器件后仍然无法录制音频？

    菊花链：

    此应用手册提供了有关如何在此模式下进行配置的说明：  

    具有共享 TDM 和 I2C 总线的多个 PCm6xx0器件

    标准模式：

    寄存器转储。

    此致

    你好，Daveon

    不完全相同、我们分别使用两个连接到两个 PCM6260的 SAI、SAI2和 SAI3、如下图所示。I2C 使用相同的 I2C 总线

    。

    PCM6240都可以正常读取和写入 I2C 数据、驱动程序可以读取这些数据。 当驱动程序未安装时、您可以使用 i2cdump–y 2 0x48来查看 Reg 值。

    3.. PCM6260引脚28 GPIO1未连接到 MCLK、但设置为中断输出。 它可以正常记录吗？

    大家好、Gareth：

    我不确定您的映像是否正确写入/配置器件。 我建议确认从地址是否正确、例如器件 A 为90hex、器件 B 为92。我还建议在 PurePathConsole 3中配置器件、执行寄存器转储、然后根据该文件写入器件。

    下面是两种器件的4通道差分输入、32位字长、TDM 的示例

    //器件 A

    你好，Daveon

    您可以在 PurePath 中看到 PCM6240 (如附件 ppc3.png)。 修改设置后、我使用了 Windows 的内置录制程序、但没有录制声音。 是否使用内置录制程序进行录制？ 或者使用 PurePath 控制台3进行记录？

    大家好、Gareth：

    如果您使用 EVM 进行评估、则设备录制过程有3个选项(USB、Optical 或 External ASI)。 EVM 用户指南的第2.1节对此进行了说明。

    我不确定用于录制的 Windows 内置程序是什么、但您可以使用 Audacity 通过 USB 直接从 EVM 记录 DOUT 数据。 只需确保时钟速率和字长与 ASI 输入一致。 播放1kHz 输入音调、您应该会看到"Audity"中相应的正弦波。

    PurePathConsole 3不记录音频数据、用作与器件直观连接的配置/表征工具。 在 PCM6260情况下、它还可以进行实时监控诊断。

    此致、

    你好，Daveon

    现在将 PCM6260-EVB 与 PPC3配合使用、加载预设的2通道差分直流耦合麦克风输入设置值、我可以记录到 IN1和 IN2、但当我选择外部 ASI 作为选择源并将其连接到自己的板时、我也无法记录。 我是否需要更改任何设置？ 目前、客户的板 GPIO 无法向 PCM6260-EVB 提供 MCLK。 这是否会产生影响？

    您好！

    MCLK 输入是可选的、BCLK、FSYNC 和 DOUT 就足够了。 在运行过程中、器件只需要电源、正确的时钟和模拟输入。 因此、我建议确认 EVM 测试点上的 BCLK 和 FSYNC 频率。 您测量什么、PPC 会在"音频串行总线"选项卡上识别它？

    此致、
