[参考译文] TAS2563：TAS2563 Linux 驱动程序支持 PDM？？

请使用此驱动程序。  tas2781-linux-drivers/tas2781-linux-driver - Unnamed repository；编辑此文件'description'以命名存储库。

该链接中的指南还提供了

请提供以下信息：

音频格式：I2S 或 tm、位宽、采样率

除了纯回放和录制之外,您的项目是否同时支持回放和录制。

我将为您上传 Jason 文件、其中包含寄存器设置。

还有一点、一台设备中有多少个 tas2563？

尊敬的盛道：

非常感谢您的快速和称职的回复！

该项目使用一个 TAS2563、使用 TAS2563将像一个内部通信(同时播放和录制) 对于带一个扬声器和两个 PDM 麦克风的泊车系统、使用两个麦克风的想法是获得更高的质量、或在稍后实施波束形成以稍微补偿环境噪声。

音频格式为 I2S (使用 TAS2563RPPT 的 FSYNC、SBCLK1、SDOUT1和 SDIN1与 i.MX8M Plus 通信)、两个 PDM 麦克风将连接到 PDMCLK 和 PDMD。

请根据您的经验选择采样速率和位宽,我想我们的 Linux 软件人员会联系您,不管怎样;-)

此致

赫伯特

此外、您是否需要 Rx ref 信号？ 在我们的其他项目中、不仅需要来自 PDM 麦克风的记录数据、还需要 Rx 参考数据(echo ref data)。

"我不知道你在说什么,我不知道你在说什么。"

我找不到相应的硬件引脚、因此这肯定是与软件相关的问题、您能否进一步说明？

好的、我来进一步解释一下。

我们的大部分 PDM 项目、音频 Rx 路径为 I2S、32位、16kHz 或48kHz (tas2563支持的最小音频间隔为32位、立体声、16kHz、请检查您的平台是否支持此功能)

通常、发送路径为4槽、16位、采样率与接收路径相同。 TX 路径中的信号是插槽0是 PDM 左麦克风数据、插槽1是 PDM 右麦克风、插槽2是回声参考数据(比 Rx 数据小约-6dB)。 ，

请检查您将使用的 tas2563的封装类型：QFN 或 WCSP。 确认后、您将申请相关的 ppc3工具。

希望这可以帮助您。

感谢您的反馈。

您好，Shenghao：

我已尝试 按照文档从 git.ti.com/.../集成驱动程序。 很遗憾、我遇到了一些生成错误(下面附加了日志)。

似乎该驱动程序与我们使用的内核版本不兼容-我们是在5.15.71 (NXP i.mx8m-plus)。 您是否有与此内核兼容的驱动程序或其他解决方案来解决此问题？

此致、Christian
