Apologies if this has been answered elsewhere but I have been unable to find anything. I am new to the CyAPI and am trying to write a C++ application to communicate with a CY7C68013A. However, whenever I attempt a read/write to the control endpoint, I see an error 997. The functional part of my code is here:
CCyControlEndPoint *ept = USBDevice->ControlEndPt;
ept->Target = TGT_DEVICE;
ept->ReqType = REQ_VENDOR;
ept->Direction = DIR_TO_DEVICE;
ept->ReqCode = 0xA0;
ept->Index = 0x0000;
unsigned char buf[64];
ZeroMemory(buf, 64);
ept->Value = 0xE600;
LONG buflen = 1;
buf[0] = 1;
ept->XferData(buf, buflen);
ept->Direction = DIR_FROM_DEVICE;
ept->Value = 0xE60A;
buflen = 1;
ept->XferData(buf, buflen);
cout << "Data: " << hex << (int)buf[0] << dec << "\nError code: " << ept->LastError << '\n';
According to the documentation I've seen, this register should output a value of "1"; however, I get "5e". In fact, for any register I try to access, I get "5e 6f" repeating. Is there something I am missing about setting up the control endpoint or how I'm using it?
Thanks,
Scott
