esp32-s3 i2s读取es7210超时
Posted: Mon May 05, 2025 3:50 pm
硬件是立创实战派s3，也就是一个i2s的DI连接es7210和DO连接es8311，配置过程中读取es7210超时，i2s_channel_read返回ESP_ERR_TIMEOUT（这个函数除了返回ESP_OK就是这个），i2s的配置参考小智AI的box-s3的配置，设置tx工作在std模式下，rx工作在tdm模式下，i2s配置如下：
如果将双工模式改成单工，也就是下面这段代码：
这样单工模式可以正常读取，es7210配置部分采用官方的组件包，应该不会有问题，这种一个i2s设备同时连接es7210和es8311的设计在官方的box-s3上似乎也存在，我应该修改i2c的配置部分，还是更改i2s配置？
