Hello All!
Take a look at this code. When I associate ptr[0]... to viWriteBuffer[12]... the values do not copy correctly. The values for iOutputPtr in the ASCIItoHex function are correct, but when I create my variable ptr, I have problems.
int index = 0;
int ptr[8];
char idArray[NUMBER_OF_LCMS];
...
GetPanelHandleFromTabPage (panelHandle, PANEL_TAB, TAB_TWO, &tabHandle);
GetCtrlIndex (tabHandle, TABPANEL_2_ALL_LIGHTS, &index);
GetLabelFromIndex (tabHandle, TABPANEL_2_ALL_LIGHTS, index, idArray);
ASCIItoHex( idArray, ptr );
viWriteBuffer[12] = ptr[0];
viWriteBuffer[13] = ptr[1];
viWriteBuffer[14] = ptr[2];
viWriteBuffer[15] = ptr[3];
viWriteBuffer[16] = ptr[4];
viWriteBuffer[17] = ptr[5];
viWriteBuffer[18] = ptr[6];
viWriteBuffer[19] = ptr[7];
status = viWrite( gateway, viWriteBuffer, viWriteBufferSize, viWriteDataSize );
//The contents of viWriteBuffer[12-19] are not what they are supposed to be (they should be the same as the values in
//iOuputPtr in my ASCIItoHex function.
void ASCIItoHex( char cInputStr[], int iOutputPtr[] )
{
int iInputStr[33] = {0};
int length = 0;
int i = 0;
int k = 0;
int errorCheck = 0;
int outputByteStr[8] = { 0x00 };
length = strlen(cInputStr);
//convert input string to integers 0 through 16
//Requires that input not have spaces letters must be in capitals
for( i = 0; i < length; i++ )
{
iInputStr[i] = (int) cInputStr[i] ;
if(iInputStr[i] <= '9' && iInputStr[i] >= '0') //iInputStr between 0 and 9
{
iInputStr[i] -= 48;
}
else if( iInputStr[i] <= 'F' && iInputStr[i] >= 'A')
{
iInputStr[i] -= 55;
}
else if( iInputStr[i] <= 'f' && iInputStr[i] >= 'a')
{
iInputStr[i] -= 87;
}
else if( errorCheck != 1 )
{
MessagePopup( "Input Error", "Non-hex value entered, check value and re-enter." );
errorCheck = 1;
}
}
for( i = 0; i < (length); i += 2 )
{
outputByteStr[k] = (( 16 * iInputStr[i] ) + iInputStr[i+1]);
k++;
}
iOutputPtr = outputByteStr;
}
