Hi, I have two functions. One converts ascii to hex and the other uses the function and displays the inverted data. I have shown the two functions below Code: /*----------------------*/ /* Convert ASCII to hex */ /*----------------------*/ unsigned int asc2hex(char *str) { unsigned int res; char *p; res = 0; for (p = str; *p != '\0' ; ++p) { res <<= 4; if (*p >= '0' && *p <= '9') res |= *p - '0'; else res |= *p - 'A' + 10; } return res; } Code: /*----------------------*/ /* Invert data */ /*----------------------*/ invdata( int cycle, char *actstr, char * userData) { char this_input_data[1024]; unsigned int val; get_facvalue(userData, cycle, this_input_data); val = asc2hex(this_input_data); sprintf(actstr,"%08u",~val); return 0; } The above functions work perfectly well. But, when I try to do the same and display the result in binary I don't get the proper result. The result just shows "b". I have shown the two functions below Code: /*----------------------*/ /* Convert ascii to binary*/ /*----------------------*/ unsigned int asc2bin(char *str) { unsigned int res; unsigned int binres; char *p; binres = 0; for (p = str; *p != '\0' ; ++p) { if (*p >= '0' && *p <= '9') res = *p - '0'; else res = *p - 'A' + 10; binres <<= 4; switch(res) { case '0': binres|='0000';break; case '1': binres|='0001';break; case '2': binres|='0010';break; case '3': binres|='0011';break; case '4': binres|='0100';break; case '5': binres|='0101';break; case '6': binres|='0110';break; case '7': binres|='0111';break; case '8': binres|='1000';break; case '9': binres|='1001';break; case 'A': binres|='1010';break; case 'B': binres|='1011';break; case 'C': binres|='1100';break; case 'D': binres|='1101';break; case 'E': binres|='1110';break; case 'F': binres|='1111';break; case 'a': binres|='1010';break; case 'b': binres|='1011';break; case 'c': binres|='1100';break; case 'd': binres|='1101';break; case 'e': binres|='1110';break; case 'f': binres|='1111';break; default:break; } } return binres; } Code: /*----------------------*/ /* Invert data */ /*----------------------*/ invdata( int cycle, char *actstr, char * userData) { char this_input_data[1024]; unsigned int val; get_facvalue(userData, cycle, this_input_data); val = asc2bin(this_input_data); sprintf(actstr,"%032b",~val); return 0; } Can you tell me what is wrong? Thanks!
