i tried all your suggestion but nothing works. hardware is ok....
i don't know what to do...
could you please compile the program for my pic (16F876) and post the hex file and the lst file?
also the thing with the errors doesn't help. it just prints something like:
received
Ÿ@ : no errors
Û ï: no errors
Û ï: no errors
: no errors |

i would be very happy if this one works:
| Code: | #include <16F876.h>
#use delay (clock=20000000)
#use RS232 (baud=19200, xmit=pin_c6, rcv=pin_c7,bits=8,parity=n,errors,stream=STDERR)
#use standard_io(c)
#fuses HS, NOWDT, NOPROTECT, PUT, NOBROWNOUT, NOLVP
#include <errno.h>
#include <stdio.h>
#include <stdlib.h>
char input=0;
#int_rda
void serial_isr()
{
input=getc();
}
main()
{
enable_interrupts(int_rda);
enable_interrupts(global);
while (1)
{
delay_ms(1000);
printf("%C ",input);
printf("received ");
}
} |

Note that I commented out some includes to shorten the lst file (only for the lst file, the hex is exactly how you posted the code).
I changed the device to an 18F452 (because that is what I am currently working with) and the programmed worked as expected.

I compiled your program with PCM vs. 3.110 and I examined the .LST
file. (I commented out the #nolist statement in 16F876.H, so I could
see all the code).
I found the string "no errors" in the string.h file, in the strerror()
function. But there's no code compiled for it. It doesn't appear
in the program.
Somehow, in your program, with your compiler, strerror() is being
compiled. I don't yet understand what's going on. I copied your
code verbatim into MPLAB. There is some crucial difference between
your compiler/editor environment and mine. Something is causing
strerror() to be put into your program. Or, the program you posted
is not the same as the one you're testing. |

no, sorry, i didn't post the program with the error thing. i thought that couldn't solve my problem
BUT I downloaded the hexfile from Mark and it works!!!!! output is: u received u received u received u received
so what am i doing wrong?? did i forget some settings? this is my lst file: | Code: | CCS PCM C Compiler, Version 3.110, 15948

Mark used vs. 3.206 to compile the file. Try this one.
I compiled it with vs. 3.110.

Compile the source code that you posted on August 2 (just above)
and then compare the HEX file to the one that I posted. You can do
this by opening a DOS window and using the fc.exe file comparison utility.
Example:
fc /b "\program files\picc\projects\test\test.hex" c:\temp\test.hex
(Or, post your hex file, and I'll compare them). |

fc says that your hex file is longer than mine... if you want to test it yourself here is my hex file: | Code: | :1000000000308A006B280000FF00030E8301A1006E

OK, if your hex file (the correct one) is the same as my HEX file,
and my HEX file works on your system, then what does this mean ?
Possibilities:
1. The file that you are programming into your PIC may not be the
file that is created when you compile. ie., You may be using some
old HEX file from a different directory than your project directory.
So even though you make all sorts of changes to your source
and try them, nothing ever seems to work because you're not
programming the latest file into the PIC. You need to check
if this is happening.
2. When you import a HEX file into MPLAB and then program it into
the PIC, it's a different process than compiling a file and programming
it. It's possible that the fuse settings ("config bits") are not being
properly updated by MPLAB before it programs the PIC. I have seen
this happen on older versions of MPLAB (4.xx perphaps) but I've
not seen it recently. Right before you program the PIC, you need
to look at the window that has the Config Bit settings and verify
that they match the ones in your program.
3. Also, I don't know what programmer you're using. Can you tell us ?
There are settings within the programmer setup window, that allow
you to reduce the address range which is programmed. If you
reduced it too much, then not all of your program would be burned
into the PIC. Are you doing anything like this ? |
