Now have a hexadecimal data STR="B5 62 06 00 00 14 01 00 00 00 D0 08 00 00 00 C2 07 00 00 03 01 00 00 00 00 00 C0 7 e",
Call a function returns the hexadecimal data not return a string, can you tell me how to achieve?

CodePudding user response:

Is to convert hexadecimal string to integer array? Read characters from a string once and then converted to a decimal line

CodePudding user response:

 
Unsigned char * __fastcall StrToHex (const AnsiString& HexStr) 
{
Unsigned char * result=new unsigned char (hexStr. The Length ()/2); 
Unsigned char * pbufs=the result; 

Char * pData=(https://bbs.csdn.net/topics/hexStr.UpperCase). C_str (); 

for(int i=0; i {
Unsigned char val=pData [I] - '0'; 

If (val & gt; 0 xf) 
Val -=7; 

If (I % 2==0) 
{
* pbufs=val. 
* pbufs & lt; <=4; 
} 
The else 
{
* pbufs |=val; 
PBuf++; 
} 
} 

return result; 
} 

Pay attention to release the returned data buffer,
