float temperature2;
char Add_Radio[4];
printf("[%s200%8.2f]\r",Add_Radio,temperature2);
when i use this code all positive values on my rs232 terminal are good but not the negative.
Add_Radio[]=[210]
temperature2=-1
and the print stop like that:
[210200
what's the problem ?! :( |

Post a small test program, that you have compiled on your PC.
The code in your post is "typed in" code. It's far better if you
post a test program with real code. Also post your compiler version. |

PCWH version 4.032
my solution is :
sprintf(mystring,"[%s400%8.2f]",Add_Radio,temperature4);
printf("%s\r\n",mystring); |
