几天前,我用FX2内的8051创建了包,并在工作中使用。转移率达到48 Mbps。
我认为原因是,他们得到的数据从60 Mbps速率FIFO和我写FIFO 48 Mbps。所以我不能及时填写FIFO。当我使用高速ISO端点每微帧和双缓冲三包,很明显,传输失败。
我想是没有办法用FX2与两高速ISO EPS分别为双缓冲。
如果你对此有什么意见,请告诉我。

Hi again
Some days ago, I created packets using 8051 inside FX2 and in worked. Transfer rate reached 48 MBps.
I think the reason is that, SIE gets data from fifo with rate of 60 MBps and I write to fifo with 48 MBps. So I can not fill fifo in time. When I use High-Speed ISO endpoint with 3 packets per microframe and double buffering, it is obvious that transmission fails.
I think there is no way to use FX2 with two High-Speed ISO EPs with double buffering for each of them.
If you have any opinion about it, let me know please.
