[En-Nut-Discussion] ASCII to hex

[Alexander Baranov]

Hi
maybe this helps until seniors propose something like atoi()?

unsigned char pack_char_to_hex (unsigned char* psrc)
{
 unsigned char m0,m1;

   m0 = *psrc;
 if((m0 >=0x30)&&(m0<=0x39)){
  m0 = m0 - 0x30;
 }
 else if((m0 >=0x41)&&(m0<=0x46)){
  m0 = m0 - 0x41+0x0A;
 }
 else if((m0 >=0x61)&&(m0<=0x66)){
  m0 = m0 - 0x61+0x0A;
 }
 else{
  m0 = 0;
 }

 m1 = *(psrc + 1);
 if((m1 >=0x30)&&(m1<=0x39)){
  m1 = m1 - 0x30;
 }
 else if((m1 >=0x41)&&(m1<=0x46)){
  m1 = m1 - 0x41+0x0A;
 }
 else if((m1 >=0x61)&&(m1<=0x66)){
  m1 = m1 - 0x61+0x0A;
 }
 else{
  m1 = 0;
 }

 return ( (m0<<4)+m1);
}
