整型数组（byte,int,long,dword）转为 Hex字符串
Byte Array To Hex String
源代码
byte GBF_Convert_ByteArrToHexStr(byte rawData[], dword datalen, char outHexStr[])
{
word i;
word hexLength;
word byteIndex;
byte tmpVal;
byte retVal;
char tmpStr[gcText10];
char tmpErrStr[gcText200];
const byte dataType = 2;
// Init to failed
retVal = gcNok;
// Reset output array
for (i = 0; i < elcount(outHexStr); i++)
{
outHexStr[i] = 0;
}
// get the hex length
hexLength = datalen * dataType;
//check that the supplied output array can hold the hex string
if ( elcount(outHexStr) < hexLength )
{
snprintf(tmpErrStr, elcount (tmpErrStr), "GBF_ConvertIntArrToHexStr: ERROR: char array to small, Hex Data is %d but outHexStr only contains %d elements!", hexLength, elcount(outHexStr));
GBF_AddErrorInfo(tmpErrStr);
}
else
{
//All checks went fine, convert data
for (i = 0; i < hexLength; i++)
{
// The byte index to use for accessing rawData
byteIndex = i / dataType;
tmpVal = ((byte)(rawData[byteIndex] >> (4 * (dataType -1 - (i % dataType))))) & 0x0F;
// Convert value to a temp string.
snprintf( tmpStr, elcount(tmpStr), "%X", tmpVal );
strncat(outHexStr, tmpStr, elcount(outHexStr));
if(i % dataType == dataType-1)
strncat(outHexStr, " ", elcount(outHexStr));
}
retVal = gcOk;
}
return retVal;
}
测试代码：
{
byte in_int_array[4]={0x10,0x20,0x30,0x40};
char out_char_array[40];
GBF_Convert_ByteArrToHexStr(in_int_array,4,out_char_array);
write("out_char_array = %s ",out_char_array);
}
输出结果：
out_char_array = 10 20 30 40
Int Array To Hex String
源代码
byte GBF_Convert_IntArrToHexStr(int rawData[], dword datalen, char outHexStr[])
{
word i;
word hexLength;
word byteIndex;
byte tmpVal;
byte retVal;
char tmpStr[gcText10];
char tmpErrStr[gcText200];
const byte dataType = 4;
// Init to failed
retVal = gcNok;
// Reset output array
for (i = 0; i < elcount(outHexStr); i++)
{
outHexStr[i] = 0;
}
// get the hex length
hexLength = datalen * dataType;
//check that the supplied output array can hold the hex string
if ( elcount(outHexStr) < hexLength )
{
snprintf(tmpErrStr, elcount (tmpErrStr), "GBF_ConvertIntArrToHexStr: ERROR: char array to small, Hex Data is %d but outHexStr only contains %d elements!", hexLength, elcount(outHexStr));
GBF_AddErrorInfo(tmpErrStr);
}
else
{
//All checks went fine, convert data
for (i = 0; i < hexLength; i++)
{
// The byte index to use for accessing rawData
byteIndex = i / dataType;
tmpVal = ((byte)(rawData[byteIndex] >> (4 * (dataType -1 - (i % dataType))))) & 0x0F;
// Convert value to a temp string.
snprintf( tmpStr, elcount(tmpStr), "%X", tmpVal );
strncat(outHexStr, tmpStr, elcount(outHexStr));
if(i % dataType == dataType-1)
strncat(outHexStr, " ", elcount(outHexStr));
}
retVal = gcOk;
}
return retVal;
}
测试代码：
{
int in_int_array[4]={0x1011,0x2022,0x3033,0x4044};
char out_char_array[20];
GBF_ConvertIntArrToHexStr(in_int_array,4,out_char_array);
write("out_char_array = %s ",out_char_array);
}
输出结果：
CAPL / .NET out_char_array = 1011 2022 3033 4044
总结
根据上面两个例子
只要将byte GBF_Convert_ByteArrToHexStr(byte rawData[], dword datalen, char outHexStr[])
改为byte GBF_Convert_LongArrToHexStr(long rawData[], dword datalen, char outHexStr[])
然后再将const byte dataType = 4;改为const byte dataType = 8;即可实现long 整型数组转为hex字符串。
Hex字符串转为 整型数组（byte,int,long,dword）
Hex String To Byte Array
源代码
byte GBF_ConvertHexStrToByteArray(char hexRawData[], byte outByteArr[])
{
word i;
word offset;
word hexLength;
byte tmpVal;
byte retVal;
char tmpErrStr[gcText200];
byte outdword;
const byte dataType = 2;
// Init to failed
retVal = gcNok;
offset = 0;
// Reset output
outdword = 0;
// get the hex length
hexLength = strlen(hexRawData);
//remove possible "0x" at the beginning
if( hexRawData[0] == '0' && hexRawData[1] == 'x' )
offset = 2;
//check that the a dword (4 bytes) can hold the hex string
if ( dataType < (hexLength - offset)/2 )
{
snprintf(tmpErrStr, elcount (tmpErrStr), "GBF_ConvertHexStrToInt: ERROR: Hex Data is %d which is more than a dword can hold!", hexLength);
write ("Error in GBF_ConvertHexStrToInt: string is: %s",hexRawData);
write(tmpErrStr);
}
else
{
retVal = gcOk;
//All checks went fine, convert data
for (i = offset; i < hexLength; i++)
{
outdword = outdword << 4; //shift the result
// convert the Hex data and validity check it
tmpVal = (byte)hexRawData[i];
if (tmpVal >= 0x30 && tmpVal <= 0x39) //0-9
tmpVal = tmpVal - 0x30;
else if(tmpVal >= 'A' && tmpVal <= 'F') //A-F
tmpVal = tmpVal - 0x37;
else if (tmpVal >= 'a' && tmpVal <= 'f') //a-f
tmpVal = tmpVal - 0x57;
else
{
snprintf(tmpErrStr, elcount (tmpErrStr), "GBF_ConvertHexStrToInt: ERROR: Invalid Hex data found in Hex string at position %d", i);
write(tmpErrStr);
retVal = gcNok;
break;
}
outdword = outdword | tmpVal; //one nibble at a time....
if(i%dataType == dataType-1)
outByteArr[i/dataType] = outdword;
}
return retVal;
}
测试代码：
{
char in_char_array[5]="1234";
byte out_byte_array[20];
GBF_ConvertHexStrToByteArray(in_char_array,out_byte_array);
write("out_byte_array ={0x%x,0x%x} ",out_byte_array[0],out_byte_array[1]);
}
输出结果：
CAPL / .NET out_byte_array ={0x12,0x34}
Hex String To Int array
源代码
byte GBF_ConvertHexStrToIntArray(char hexRawData[], int outByteArr[])
{
word i;
word offset;
word hexLength;
byte tmpVal;
byte retVal;
char tmpErrStr[gcText200];
int outdword;
const byte dataType = 4;
// Init to failed
retVal = gcNok;
offset = 0;
// Reset output
outdword = 0;
// get the hex length
hexLength = strlen(hexRawData);
//remove possible "0x" at the beginning
if( hexRawData[0] == '0' && hexRawData[1] == 'x' )
offset = 2;
//check that the a dword (4 bytes) can hold the hex string
if ( dataType < (hexLength - offset)/2 )
{
snprintf(tmpErrStr, elcount (tmpErrStr), "GBF_ConvertHexStrToInt: ERROR: Hex Data is %d which is more than a dword can hold!", hexLength);
write ("Error in GBF_ConvertHexStrToInt: string is: %s",hexRawData);
write(tmpErrStr);
}
else
{
retVal = gcOk;
//All checks went fine, convert data
for (i = offset; i < hexLength; i++)
{
outdword = outdword << 4; //shift the result
// convert the Hex data and validity check it
tmpVal = (byte)hexRawData[i];
if (tmpVal >= 0x30 && tmpVal <= 0x39) //0-9
tmpVal = tmpVal - 0x30;
else if(tmpVal >= 'A' && tmpVal <= 'F') //A-F
tmpVal = tmpVal - 0x37;
else if (tmpVal >= 'a' && tmpVal <= 'f') //a-f
tmpVal = tmpVal - 0x57;
else
{
snprintf(tmpErrStr, elcount (tmpErrStr), "GBF_ConvertHexStrToInt: ERROR: Invalid Hex data found in Hex string at position %d", i);
write(tmpErrStr);
retVal = gcNok;
break;
}
outdword = outdword | tmpVal; //one nibble at a time....
if(i%dataType == dataType-1)
outByteArr[i/dataType] = outdword;
}
return retVal;
}
测试代码：
{
char in_char_array[9]="12345678";
int out_byte_array[20];
GBF_ConvertHexStrToIntArray(in_char_array,out_byte_array);
write("out_byte_array ={0x%x,0x%x} ",out_byte_array[0],out_byte_array[1]);
}
输出结果：
CAPL / .NET out_byte_array ={0x1234,0x5678}
总结
如果是想实现 Hex String To long array ,只需要将
byte GBF_ConvertHexStrToIntArray(char hexRawData[], int outByteArr[])改为byte GBF_ConvertHexStrToLongArray(char hexRawData[], long outByteArr[])
int outdword; const byte dataType = 4;改为long outdword; const byte dataType = 8;
