CYW43907 DMA示例

亲爱的柏树，
我想建立Wi-Fi到USB适配器。据我了解，我应该将USB子系统初始化为CDC类设备模式，然后将请求和响应转换为主机（PC）。
现在我将使用WiGeTyHtPSPGET函数从HTTP服务器获取数据，并将响应转换为USB。如何将该函数的空*缓冲区加到CYW43907的高速内部数据通道上？我应该为此使用DMA吗？你能给出关于CYW43907的DMA配置的例子吗？
也许你有任何例子，如AXI之间的数据交换，如USB，UART，以太网与Wi-Fi CPU？
谢谢您！

  Dear Cypress,

I would like to build Wi-Fi to USB Adapter. As far as I understood I should initialize USB subsystem as  CDC class device mode and then translate the requests and responses to host (PC).

Now I'm going to use  wiced_https_get function to get data from http server and translate the response to u***. How to put void* buffer of this function to hi-speed internal data channel of CYW43907? Should I use DMA for this? Could you give the examples of dma configuration for CYW43907?

Maybe you have any examples for AXI data exchange between blocks like USB, UART, Ethernet with Wi-Fi CPU?

Thank you!
