| Serial translation question ! |

Hello !
Here is what i'm trying to do :
Let's say i have a character transmitted from serial like 0xAA (binary : 10101010).
I want to translate this command into : 0x3AA (binary : 1110101010).
How can this be done ?
Should i use a cast it to int, like this :
| Code: |
char c;
int d;
d=(int)c*
|
Thank you all ! |

Here is a small test code that isn't working:
| Code: |
#include <18f452.h>
#fuses HS,NOWDT,NOPROTECT,NOLVP
#use delay(clock=10000000)
#use rs232(baud=9600, xmit=PIN_C6, rcv=PIN_C7)
//=============================================================================
void main()
{
char c;
int d;
while(1)
{
c=getc();
d=(int)c*;
printf("%ld",d);
}
}
|
In the CCS c manual :
| Quote: |
getc( ) .... Returns: An 8 bit character |
HELP !!!!!!!! |

int is a 8-bit bit value in the CCS compiler.
why do you cast the value (btw cast with * cant work in your example)? what about
c=getc();
printf("%u",c); |

not sure what you are trying to do with c*
int is 8 bits on a pic.
try int16
| Code: |
char c;
int16 d;
while(1)
{
c = getc();
d = (int16)c + 0x300;
printf("%ld",d);
}
