error

Note that char may be signed or unsigned.

BYTE sounds very much like an unsigned data type.

Have you checked into making char unsigned?

By the way - why so very short subject for your thread? How much information is there in "error"? Why not "Error 147 while compiling USB sample code" or something similar?

Next thing - was this the application note?
www.onarm.com/.../apnt195.asp

In that case - why not supply that information in the post?

hi,

thank u for reply.

i made the correction. it is compiling now. now i got one more problem.

in the vc++ client program, after making the changes, during compilation it is giving the following error. using projectconverter i had modified the client program to vc++ 6.0

:\Documents and Settings\Administrator\Desktop\HID_Client\HID.cpp(291) : error C2065: 'localTime' : undeclared identifier
C:\Documents and Settings\Administrator\Desktop\HID_Client\HID.cpp(291) : error C2100: illegal indirection

even though i had added #include "time.h"
in hid.cpp.

expecting your kind reply.

with regards

'localTime'?

Dear sir,

i want to send multiple byte(ex. 8/16/32 bytes) from STM32 development kit to PC application through USB.

for that i'm using USBHID on STM32 development side and HID_Client program on VC++ side.

pls suggest me what are the necessity chages i have to make on both host and client side. also i'm bit confused about USAGE_MIN and Usage_Max.

pls suggest me any sample examples.

i made the following changes, code compiled with error. in this device not detected.

in Hiduser.c

BOOL HID_GetReport (void) {

/* ReportID = SetupPacket.wValue.WB.L; */ switch (SetupPacket.wValue.WB.H) { case HID_REPORT_INPUT: GetInReport(); 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);

void GetInReport (void) { int x = 0, y= 0; x = ADC_ConvertedValue; InReport[1] = x & 0xff; InReport[0] = (ADC_ConvertedValue >> 0x08);
****************************************************
In client side program

void CHIDClientDlg::OnInput()
{ // int n; int x,y; char buf[16];

x = InReport[0]; x = (x << 8); y = InReport[1]; x = x | y ;

// if (InValue == InReport[1]) return;

// if (z == x) return;
// z = x;
// InValue = InReport[1];

// for (n = 0; n < 8; n++) {
// m_Input[n].SetCheck((InValue & (1 << n)) ? 1 : 0);
// }
// sprintf(buf, "%04d", InValue); sprintf(buf, "%05x",x);

m_In.SetWindowText(buf);
}

expecting your kind reply.
