You also seem to be saying that the crystals never oscillate.
Please DO NOT KEEP REFERRING to PROTEUS. It's not helpful.
So.
On a REAL board tell us EXACTLY what works and what does not.

Everything I said is true regarding the plates.
just did a test on proteus to see the result.
when told that the crystals do not vibrate, this is the real board. no information that I spent here was the proteus, commented that only works in proteus. |

I'm not doubting your honesty. I do believe that what you say is true.
This thread is going nowhere, fast.
What I'm after, is a consice summary of the current situation.
For example, with minimal code:-
Can you make an LED toggle at the correct rate with the internal oscillator?
Can you send data at the correct rate with the UART?
Can you see the HF oscillator run?
.......................
Etc.
In other words:-
Can you test each peripheral one at a time?
Do they operate with correct amplitude and frequency?
Mike
And please do not mention Proteus again. |

Sorry if I expressed myself badly, I am Brazilian and I am using a translator.
Answering your questions:
Yes I can do a light flashes on the correct frequency.
Yes I can send and receive data through the two serial I have.
Yes, the master oscillator (20Mhz) works perfectly and I can read your frequency with the oscilloscope, something that I can not with Crystal rtc.
The rtc internal functions normally with internal crystal.
Usr can usually an lcd 20x4.
Use reading and writing the EEPROM normally
readings and outputs function normally.
Apparently everything works correctly.
I think I have to configure something to make the clock work.
Some register, do not know.
Does anyone have this pic and could do the test with the code I posted to see the result?
Even if it is in another board, because if someone is successful, it may be my compiler, it may be something specific to my board, or even any configuration. |

Have you actually tried with the line:
setup_oscillator(OSC_SOSC_ON);
added to the code suggested by andrew?.
This line is needed by some compiler versions, setting the 'go' bit for the oscillator.
When I used the secondary oscillator, it was quite a few compiler versions ago (CCS unfortunately does change how such things work), but this line was needed.

Thanks for the tip,
I had previously tested with this line, however this did not last test I put it!
Good idea!
this is the first test that I will do when I go to work.
What other possibilities for me to test? |

The basic problem is you have to run all replies through a translator
and so you don't see or understand many of the replies. For example:
andrewg said:
| Quote: |
Let me assure you that without them it is definitely NOT going to work,
and without them you're wasting everyones time.
|
Then later you (lucasromeiro) reply:
| Quote: | but even without the capacitors should work, right?
|
You ignored his direct statement that capacitors are required.
This is why there is no progress in solving the RTC problem. |

I agree it is a problem of communication exists.
but well observed responses and later I did and I put the capacitors, as shown here.
the results have not changed.
you could test it on board?
thank you |

good afternoon!
I just test the code putting the line:
setup_oscillator (OSC_SOSC_ON);
but nothing changed.
Can someone help me? |

hello, did several tests taking and putting fuses, tried changing the version of the compiler that a friend Tiha, tried by the fuses through the mplab ....
But nothing worked.
The options are running out. |

Here is some code I have got working on a PICDEM PIC18 board with a PIC 18F87K22.
I recommend always start prototyping code with WORKING hardware that use the same device as you intend to use in your own design.
I have left some lines of code commented out to show things I have tried but found to be not needed.
Hope this helps.
| Code: | #include <18F87K22.h>
#device ICD=TRUE
#device adc=16
#FUSES NOWDT //No Watch Dog Timer
#FUSES WDT128 //Watch Dog Timer uses 1:128 Postscale
#FUSES VREGSLEEP_SW //Ultra low-power regulator is enabled
#FUSES INTRC_LP //LF-INTOSC in Low-Power mode during Sleep
//#FUSES SOSC_DIG //Digital mode, I/O port functionality of RC0 and RC1
#FUSES INTRC_IO //Internal RC Osc, no CLKOUT
#FUSES PUT //Power Up Timer
#FUSES BORM_LOW //Low-power BOR
#FUSES WDT_NOSLEEP //Watch Dog Timer, disabled during SLEEP

Thanks for the help.
I will test the code and notice the results.
Already tried everything and nothing worked.
Very strange!
thank you
