16F84 to 16F628A help needed

stamiher said:

The whole circuit is imho not bad.
I will not use it as a darkroom timer but as a precision timer for inflating balloons for my wife.
She is into this business.
So the issue for the BCD switches in low light conditions does not apply to my actual needs.

@mvs sarma,
would it be to much to ask you for a version of the code for use with the internal osc?
PLEEEEAAAASE ???!!!??!!

As now Ericgibbs takes over, i shall relax, being a learner still. I will try for experience, but you are likely to get a cute software from the hands of Eric. The internal oscillator may be 8MHz and all the delays are to be re-tuned.

This is the final schematic i intend to use.

that need not be modified now and you can stop using it and it can be taken as zero, i suppose..

Sarma you're right.
That should be a zero.
Maybe i can later understand the whole code and remove the unneeded parts.

hi,
This program is now for the 16F628A, internal 4mHz clock.

It runs OK on the Oshonsoft simulator.

Its been disassembled from the hex file you posted, lets know how it goes.

Hello Eric,
and thanks a lot for the code.
I don't know if it is OK because i couldnt programm the 16F628A.

So far i have
-installed the MPLAB V8.20,
-selected the 16F628A,
-installed the FTDI drivers for my Olimex PIC-MCP-USB-MPLAB Compatible Programmer
-changed the COm Port from 1 to 4 so that the MPLAB sees the Programmer right
-and programmed the chip but got an error.

Please see for yourself.

What have i done wrong ?????

hi,

When you started the MPLAB project did you use the Wizard.??

Those config errors can be caused by the CONFIG statement in the program header, not agreeing with settings in the MPLAB configuration window.

Have you selected the MPLAB debugger and prommer options.?

I'll retry the program in MPLAB not OS.

hi,
Just started MPLAB using the Wizard and then the 'Build All' option.

It assembles OK.

Copy of Output window.

Use the Release option not Debug for a PIC.

Hello Eric,
i did not use the Wizard.
After you mentioned it i did.
It assembles OK here too.
But i haven't figured out how to set the config bits right because i get this:

"Configuration Memory has not been updated.
Press "Yes" to accept the current configuration
or "No" to abort the operation."

Try to figure out where i have to change what to get it done.
I need some time....

Thanks for your patience.
I know that i'm a totally beginner.

Regards
Stamatis

Btw is this a problem???


PICPICSTART Plus Firmware Version 04.50.06


A newer version of the PICSTART Plus firmware operating
system is available, and may be required for programming
some devices. The newer version is located in your
MPLAB IDE\PicstartPlus directory. Refer to the topic,
'Upgrading the PICSTART Plus Operating System'
in the
PICSTART Plus Help file for instructions.

hi,
In the Configuration Window is a Check Box 'Config bits set in code' Click so its checked [enabled].

Ignore the Newer Version msg at this time.

Hello Eric,

i will go crazy....

I started fresh,
used the Wizard,
selected the 16F628A,
named the project,
added the timer3m.asm file that you've send me yesterday,
used the "Build all" tool,
choosed relocatable code,
the build suceeded,
checked the config bits box as you said,
choosed the Olimex programmer which i have already updated to the latest version,
enabled the programmer in MPLAB,
and when i'm trying to programm the chip i get this:

"Configuration Memory has not been updated.
Press "Yes" to accept the current configuration
or "No" to abort the operation."

When i choose "Yes"

i get this:

Final warning from MPLAB : Failed

Any suggestions ???

Instead why not try to load the hex file without MPLAB and see whether you can program your F628A?

we can later do the research of this MPlab linkup.

Hello Sarma,
i tried to import the .HEX file and programm it with MPLAB.
No sucess.

I also don't know if the Olimex is OK. It's used out of the box.

Maybe i should use some other programm than the MPLAB to programm the PIC.
Any suggestions for that?

Thanx

Stamatis

hi,
Just programmed a 16F628A PIC, no problems, this is the Output window.

Is your prommer compatible with MPLAB.???



EDIT: Use configuration window to set the configuration bits as per the program CONFIG settings.

Hi,
the Programmer should be work with MPLAB as it is advertised as a MPLAB compatible PIC programmer.

This is the beast:
Development and Prototype boards and tools for PIC AVR and MSP430

It has USB, latest FTDI drivers, set on Virtual COM Port 4, it is recognised by MPLAB but the final result doesn't match my expectations.

I don't know if it's me or the hardware....

Im not completly sure, but I think this 'Virtual Com Port 4' has been raised by other members.??????

Which Olimex PIC programmer do you have?

I have the Olimex PIC-MCP-USB Programmer.

Made in 2007, newest software (V1.30)

@Eric , what exactly you mean by saying:
"...but I think this 'Virtual Com Port 4' has been raised by other members.??????" ????

As a problem with the settings within Windows.????

Hi, i will search the net for incopatibilities for com 4 and the olimex and will return....

Thank you.
