Hex to Ascii Conversion
PostPosted: Thu Jan 08, 2004 5:36 pm     Reply with quote
Hi

I have an 8bytes data in an array, say array1[8] which contains the ff:
0xF1 0xDD 0x66 0x04 0xA3 0xDE 0x9B 0x0D ---> all in hex

I want to convert this data into ascii as:
F1DD6604A3DE9B0D ---> all in ascii character stored in an array2[16]

Anyone in the community who can provide help, snippet or any info.

Thank u.
Haplo

The easiest (but not necessarily the most efficient) way that comes to mind is:


Code:


byte I;
char Temp[2],array2[16];

for(I=0;I<8;I++)
{
    sprintf(Temp,"%X",array1[I]);
    Array2[I*2]=Temp[0];
    Array2[I*2+1]=Temp[1];
}

Hi,

Code:
const char HEX[] = {0123456789ABCDEF};

char Array1[8], Array2[16];

for(i = 0; i < 8; i++) {
     Array2[i*2] = HEX[Array1[i] >> 4];
     Array2[(i*2)+1] = HEX[Array1[i] & 0x0f];
     }
