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. |

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];
