Bulk传输是否可以被Interrupt传输打断？

[XY_772]

我用win10电脑与FX3设备进行通信，需要用Bulk传输从FX3读取大批量数据，但同时每100ms需用Interrupt EP去读取少量数据，驱动使用的Cypress的。

想问一下Bulk传输过程中，发起中断传输，这次中断传输事务会打断当前的Bulk传输嘛？

Hello,

From the description, I understand that you want BULK and Interrupt transfers.

Yes, it would be possible to transfer data over USB on Interrupt and BULK endpoints. FX3 will send/ receive the data based on the USB requests from the host.

Please let us know the application in detail so that we can help you better.

Hello,

根据内容来看，大概是关于BULK和中断之间的切换问题。
是的，中断和BULK Endpoints的USB数据传输有可能切换。FX3将根据Host端的USB请求发送/接收数据。
请告知我们更多细节以便我们提供更多帮助

Hello @Rashi_Vatsa 

Thank you for reply.

There are two interrupt endpoints and one bulk endpoint in my design.

Interrupt out:PC start a send request every 100 ms(data size 128*16 byte)

Interrupt in:PC start a receive request every 100 ms(data size 128*16 byte)

Bulk in:Manually start a receive request(data size 0~2G byte)

I worry about that when bulk is transfering  , it will affect two interrupt EP work?

Hello,

中断不应该被BULK相关的切换影响。USB的Host端规划USB的请求。FX3将基于数据的获取来响应USB的请求。

The interrupt transfers should not be affected by BULK transfers.  The USB host schedules the USB requests. Fx3 will respond to the requests based on the availability of the data
