ASCII Number to Integer or Long Integer or Hex Number
PostPosted: Fri Oct 15, 2004 7:52 am     Reply with quote
Hello der,

The code snippet in this topic will convert an ASCII number serial stream into an interger, or long integer or a Hex formatted number.

Code:


// convert ascii number string to integer number
unsigned int8 asciiNum2Int(unsigned int8 index)
{
   unsigned int8 n;

   n = RXbuffer[index];

   if ((n<='9')&&(n>='0'))
      return (n&0x0F);     // Pure number 0 to 9
   if ((n<='F')&&(n>='A'))
      return ((n&0x0F)+9); // Hex nnumber A to F
   if ((n<='f')&&(n>='a'))
      return ((n&0x0F)+9); // Hex in lower case

   return (0);
}

// convert ascii number to interger number
unsigned int8 ascii2int8(unsigned int8 indx)
{
   unsigned int8 cnvt=0;

   cnvt = (asciiNum2Int(indx)*10) + asciiNum2Int(indx+1);

   return(cnvt);
}

// convert ascii hex number to long integer number
unsigned int16 asciiHex2int16(unsigned int8 indx)
{
   unsigned int16 addr=0;

   addr = ((asciiNum2Int(indx))*4096) + ((asciiNum2Int(indx+1))*256) +
          (asciiNum2Int(indx+2)*16) + asciiNum2Int(indx+3);

   return(addr);
}



Hope this would be of great help to any PIC user.

Since I requested this code from you I have to thank you here in public for your responce. Thank you rrb011270 for your help and your patience.

And I have to thank also all of you that you are so kind to answer to questions and to help other people that you dont know.

I am involved in a project and I have to learn about programming PIC the hard way that is asap. Without this forum I would have half the knowledge I have now.

I hope that one day I will be able to contribute to this forum as you all do.

Once again thank you rrb011270. Very Happy
