What if i use xferloop to get data from camera in Hsync active low( idle state- not included data),

What happen in windows application?

And what is best way to use xferloop in above circumstance?

Hi,

Camera will be continuously pushes the data into FX2LP's slave FIFO interface based on the control signals (Hsync and Vsync).

Suppose you configured the endpoints in FX2LP to auto mode, bulk transfers..

These are the possibilities that can happen:

1. Xferdata is happening slower than the input data rate at slave FIFO interface - Data will be dropped between camera and slave FIFO interface.

2. Xferdata is happening faster than the input data rate at slave FIFO interface - Endpoint will NAK the IN tokens coming from the PC. endpoint will reply with data only when endpoint is full with data.

Regards,

sai krishna.

i think if Xferdata is happening faster than the input data rate at slave fifo interface. then FIFO fater empty than Full data.

So if i use FLAG, maybe it is possible solver. how do you think about this?
