usb hid to increase byte transfer from kit to pc

Can you, please, tell use why you think anyone would care to read your code, if you can't even read the instructions, and format it as code? Does it look readable to you?

The instructions on how to post code are clearly visibile just above the message input box.

Dear Mr.WesterMark

sorry. i'm new to the forum. so that i'd noticed the formating.

i'd modified as per your instruction in the following to send more bytes
from kit to pc (for example 2 bytes)

//*******************************************
//in demo.c

BYTE InReport[INREPORT_SIZE];

void GetInReport (void) {
        InReport[1] = 0x55;
        InReport[0] = 0xaa;
}

    GetInReport();
    //USB_WriteEP(0x81, &InReport, sizeof(InReport));
    USB_WriteEP(0x81, &InReport[0], sizeof(InReport));
  }
}
#endif

void USB_EndPoint1 (DWORD event) {
  GetInReport();
//  USB_WriteEP(0x81, &InReport, sizeof(InReport));
  USB_WriteEP(0x81, &InReport[0], sizeof(InReport));
}

        EP0Buf[0] = InReport[0];   //**********
        EP0Buf[1] = InReport[1];   //**********
      break;
    case HID_REPORT_OUTPUT:
      return (FALSE);        /* Not Supported */
    case HID_REPORT_FEATURE:
      /* EP0Buf[] = ...; */
      /* break; */
      return (FALSE);       /* Not Supported */
  }
  return (TRUE);
}

        x = InReport[1];
        x = (x << 8);
        y = InReport[2];
        x = x | y ;

  m_In.SetWindowText(buf);

.

if you intend to send 2 bytes, why doesn't your report size reflect that?

HID_ReportSize(1),

hi Tamir Michael,

i'd modified the hid report size to 64 through Inreport size. it highlighted in Bold

/* HID Report Descriptor */
const BYTE HID_ReportDescriptor[] = {
  HID_UsagePageVendor(0x00),
  HID_Usage(0x01),
  HID_Collection(HID_Application),
    HID_UsagePage(HID_USAGE_PAGE_BUTTON),
    HID_UsageMin(1),
    HID_UsageMax(2),
    HID_LogicalMin(0),
    HID_LogicalMax(0xff),
//  HID_ReportCount(8),
//  HID_ReportSize(2),
 HID_ReportCount(8),
    HID_ReportSize(INREPORT_SIZE), 
    HID_Input(HID_Data | HID_Variable | HID_Absolute),

only the output(Led indication) is 1 byte.

with regards
