Questionintel Hex file creator from Txt File Pin
Psudonym21-Aug-17 21:31

Guys,

I am working on creating intel.hex file from the inputted .txt file. The format of Intel Hex file is

Steps that I follow....

1. Input a .txt file using combo-box and browse button (working fine)
2. Read .txt file using StreamReader (Working fine)
3. Read a single line of the txt file as string (working fine)
4. Get the length of the string ( Now here is a twist)
If I just do str.length, I get the length of the string but it is not of use for me...
Lets take an example of a txt file having data 123456GCTJ
the string str = "123456GCTJ" and str.length = 10
However, since I am converting this text to intel hex format, the string is actually this way...
12, 34, 56, G, C, T, J -> Length = 7
Now, I have to do this dynamically.
Question 1. How to get the string length? Do I have to write my own function? or Do I have to define a public class and associate it with the string like... str.getlengthForIntel()

5. Once, I have length, append the data to the format i.e. Start of Frame + Address + Data + checksum
(Working Fine)

6. Checksum (how to get the checksum? I have written below piece of code which I doubt will work once we have solution to above question)

private string GetChecksum(string strData)
       {
           byte checksum = 0;
           char[] DataArray = strData.ToCharArray();
           byte ArrayLen = 0;
           string strAscii;

           //Add all bytes of the string
           while (ArrayLen < strData.Length)
           {
               if ((DataArray[ArrayLen]) != ':')
               {
                   checksum += (byte)(GetNumberFromString(DataArray[ArrayLen], DataArray[ArrayLen + 1]));
                   ArrayLen++;
               }
               ArrayLen++;
           }

           //1's complement of the addition
           checksum = (byte)(~(int)checksum);

           //2's complement of the addition
           checksum += 1;

           strAscii = ((checksum & 0xF0) >> 4).ToString("X") + (checksum & 0x0F).ToString("X");
           return strAscii;
       }


       private byte GetNumberFromString(char cHighByte, char cLowByte)
       {
           uint uHighByte, uLowByte;
           uint uFinalNum;

           uHighByte = GetHexValueFromAscii(cHighByte);
           uLowByte = GetHexValueFromAscii(cLowByte);

           uFinalNum = (uHighByte << 4) + uLowByte;

           return (byte)uFinalNum;
       }


       private byte GetHexValueFromAscii(char Ascii)
       {
           byte HexNum;
           if ((Ascii >= 0x30) && (Ascii <= 0x39))
           {
               HexNum = (byte)(Ascii & 0x0F);
           }
           else
           {
               HexNum = (byte)Ascii;
           }
           return HexNum;
       }
