| concatinating two int8's into an int16 |

Hello C gurus,
im trying to merge two int8 values into an int16 as follows;
| Code: |
#include <16F877.h>
#fuses HS,NOWDT,NOPROTECT,NOLVP
#use delay(clock=20000000)
int8 storetemp[6]{0,1,2,3,4,5,6}
int8 i,s=0;
int8 tempmsb, templsb;
int16 templong;
main
{
while(1)
{
for(s=0; s<6; s++)
{
templong = storetemp[s++];
tempmsb = templong;
send(tempmsb);
strobe_SND();
templong = templong<<8;
templong = templong & 0xFF00;
templong = templong | storetemp[i];
templsb = templong;
send(templsb);
strobe_SND();
}
}
}
|
however, the values i obtain from templsb & tempmsb are garbage. I've serached a few of the threads, but havent been able to apply anything ive seen in there to help me. As im calling out to you. Kindly advise.
best regards, |

| I didn't look at what you had done, but CCS has a built-in function to create an int16 from two int8. Look up make16() in the manual or help file. |

As a comment on what may be wrong, what is setting 'i'...
