| fputc() NOT DEFINED |
 Posted: Thu Mar 05, 2009 12:42 pm |

Hello
I am trying to set up two serial streams with a 16F876 standard UART
and a second software defined serial port defined as a second stream
therefore I am using putc and printf for char and string output on the
standard UART stream and I want to use for the first time in my program
the c function fputc and fprintf defining the second software stream to
send the data I am using the standard 16F876.h and I get the message
with an error at the first occurrence of fputc unknown identifier fputc
any ideas please
thanks

1. Post your compiler version.
2. Post a short little test program that shows the problem.
Post the #include, #fuses, #use delay(), and #use rs232() statements,
and the main(). It should compile without errors. |

| fputc not defined |

My compiler version is 3.181
see test.c below if i change the fputc statement to a putc or a printf statement it compiles without error if i try and use either fputc or fprintf it comes up with fputc not defined or fprintf not defined what file do i go to find the reason for this error ?

Get rid of these two lines. CCS doesn't allow you to do this with streams.
In your version of the compiler, it compiles without error. In 4.087,
the compiler gives these error messages if you try to #define a stream
name as a numeric value. In other words, it fails to work in both
versions, if you use the #define statements, but in the current version
it at least gives an error, so you know to fix it.

| fputc not recognized by compiler |

I remove those two defines and leave them as two different streams defined in the two #use rs232 statements however that is not the issue...
the issue for me is the compiler doesnt recogniZe the c function "fputc" or "fprintf" for that matter , it claims they are unidentifed fputc..... so in my version 3.181 it wont compile but does when I replace the fputc line with a simple putc statement my problem is where do i go to fix this problem ?? as i want to use the second stream that doesnt use the stdio hardware uart ?
thanks for your help

It does compile with vs. 3.181, after making the changes shown in bold,
in the code below.

| fputc not recognized by compiler 3.181 |

thanks for that
I am sorry but I have done all you have suggested commented out removed the two defines and adjusted the fputc line to the correct format as fputc('$',RAD);
and i still get an error 12
unidentified "fputc" when i try to compile , i must have a problem
with an include file maybe ......
I note several defines in the h file relating to "put" and "printf" nothing about fputc or fprintf
i THINK I am going to have to download another version of the compiler as mine must have a corrupted file some where ??
from my pic16876.h file ............

| Re-install your version. See if that fixes the problem. |

Many thanks the re install did the trick I was missing some defines in the 16f876.h file see below
THank you for all your help I am sorted now best wishes Dara
