FPGA PXI-7954R with PXI-6581 adapter module - missed 1 cycle of acquisition

[engwei]

Hi,

I try to generate a simple pattern and strobe it back on the same card.

There are 2 transmitting signal : TxClk (1.02MHz), Tx

2 receiving signal: RxClk(1.02MHz), Rx

TxClk and RxClk are connected together. Rx and Tx as well.

The acquisition was missed by 1 cycle at the middle. Please refer to the picture attached.

I have included the source code too. Your help are much appreciated. Any comment are welcomes.   🙂

Hello Eng Wei,

How repeatable the missing cycle that you got?

Hi James,

There were some mistake on the cycle counts. Thanks for your advise.
