CPLD--->CY7c68013--->PC

CPLD generates incremental data, then I use BULK method, EP2 out, EP6 in,to send

data to PC, PC use bulk-loop function(Cypress Examples, i modified this VC++ code, to force PC to receive only),

I use BUSHOUND to watch the data , I find data loss during data transfer. some data

loss per 512 bytes transfer.

Need I use ping-pong transfer? How to realize it.....

I beg your reply......
 

NO,I didn't stop the counter. Because I really need to send a continuous Data, counter could not stop...

The PC should received continous data, But some data lost...

I use CyAPI,
for(;bLooping
{
BeginDataXfer(..);
-->WaitXfer(..)
-->FinishXfer(...);
}

How should I mend this procedure? Thank you AASI...

I need as fast as Cy7c68013a can achieve.Bulk transfer is the fastest way,


Dear AASI, could please tell me what should I do to avoid this data loss?
Because I need to receive continuous data. Data rate: 40MB/s



I use AUTO-IN mode in the Firmware. Config EP2 as 512B*4.
