Hello,
Any idea or tips?

Thanks

Well that's what I tried, I'm sure the sequence of producing the a cycle of quadrature is correct (A ON, B OFF -->shift 90deg--> A ON, B ON -->shift 90deg--> A OFF, B ON -->shift 90deg--> A OFF, B OFF), but there are variables such as shift timing (Sleep() in this case), cycle timer (OnTimer()) might need to fix or incorrectly manipulated.

Yes, I'm pretty sure I need to fix my coding

I'm using CString::GetAt() to get each character, not sure this is best way but the microcontroller seems to receive all bytes of the string.

CString strAllDigits, strDigit1, strDigit2, strDigit3, strDigit4, strDigit5;
unsigned char pData[5];

strAllDigits.Format("%.2f", dTT126); // 4.00 - 20.00

// Get 1st digit
strDigit1.Format("%c", strAllDigits.GetAt(0));
unsigned char* pDigit1 = (unsigned char*)strDigit1.GetBuffer(0); // 1st char
strDigit1.ReleaseBuffer();

// Get 2nd digit
strDigit2.Format("%c", strAllDigits.GetAt(1));
unsigned char* pDigit2 = (unsigned char*)strDigit2.GetBuffer(0); // 2nd char
strDigit2.ReleaseBuffer();

// Get 3rd digit
strDigit3.Format("%c", strAllDigits.GetAt(2));
unsigned char* pDigit3 = (unsigned char*)strDigit3.GetBuffer(0); // 3rd char
strDigit3.ReleaseBuffer();

// Get 4th digit
strDigit4.Format("%c", strAllDigits.GetAt(3));
unsigned char* pDigit4 = (unsigned char*)strDigit4.GetBuffer(0); // 4th char
strDigit4.ReleaseBuffer();

// Get 5th digit
if(strlen(strAllDigits) > 4)
strDigit5.Format("%c", strAllDigits.GetAt(4));
unsigned char* pDigit5 = (unsigned char*)strDigit5.GetBuffer(0); // 5th char
strDigit5.ReleaseBuffer();

pData[0] = *pDigit1; // First ASCII character of data
pData[1] = *pDigit2; // Second ASCII character of data
pData[2] = *pDigit3; // Third ASCII character of data
pData[3] = *pDigit4; // Forth ASCII character of data
pData[4] = *pDigit5; // Fifth ASCII character of data

SDSWriteFIFO(Ident, (unsigned char*)pData);

Thanks, try it before but it returns same result. It must be in SDSWriteFIFO() function itself.

mraaf 15-May-17 6:11am View

And yes, it expects ASCII characters.

Jochen,
Seems the compiler didn't support CStringA. So GetString() doesn't work. I am using VC++ 6.0.
SDSWriteFIFO() is written by me but the parameter has to be unsigned char* as per library.

LPSTR buf = strTT126.GetBuffer(0); // this also pass first byte of the string
SDSWriteFIFO(Ident, (unsigned char*)buf);
strTT126.ReleaseBuffer();

Thank you Jochen, it's make sense now: the missing data must be my missing fields for Embedded Object ID and Service Parameters.

mraaf 9-May-17 5:43am View

I have fixed the mixed up and remove the loop. However SDS data frame monitor showing missing first 2 bytes while CAN data frame monitor showing all bytes were read.

Thank you very much. It works like charm.

Hi Jochen,
Below are errors from the compiler:

Error #1:
PCHDSNAPSHOT pBuffer = NULL;
unsigned long u32NeededBufferSize;

pBuffer = malloc(u32NeededBufferSize)
...error C2440: '=' : cannot convert from 'void *' to 'CHDSNAPSHOT *'
...Conversion from 'void*' to pointer to non-'void' requires an explicit cast

Noted. Sorry about that.
Will get it once I'am back in office tomorrow.

mraaf 18-Apr-17 5:37am View

Thanks, it looks lot better now. But some of the functions still unrecognizable.

mraaf 30-Mar-17 5:46am View

Yes, thanks. I have removed it and it works now.
Appreciate it.

Thanks again

mraaf 23-Mar-17 11:06am View

Ok, appreciate your help. Thanks.
Thinking of doing it differently with same result. It will be about 90 different event strings to be dispathed from 5 child dialogs and log them all in a parent.

Again, appreciate any suggestions.

Thank you
mraaf

Hi Jochen,
I added DECLARE_DYNAMIC and IMPLEMENT_DYNAMIC but having error with the second ASSERT.

Please advise.

Thanks
