Hi all.
I really appreciate you guys to concern my past question.
(In the past thread, "For exact data transfer by using FT2232H." , I asked why the FT2232H makes data delay randomly WHILE I sent the exact data from FPGA. like below:
0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 ..)I`ve tried to access with various ways. Some told me that it is a problem of DEVICE DRIVER. I also suspected its unstable device driver.
However, I found the result which is received perfectly by SHUTING DOWN my windows programs like Quatus, VC++, Explorer etc..
It success to transfer the 18MByte data without delay but sometimes delay appears randomly in 1 or 2 points.
So I think the communication between FT2232 and PC is interfered by some window programs of PC.
Actually, I made a PC application program with no protecting the app.
I wonder if it is real problem I have? Is there some solution by modifying VC++ coding ? IF YOU have any opinion about this, please tell me about that.
Thanks. Paul
