need change km
kymco xtown 300
18f87k90
original 45464
need 10000 and 18000

[junmab]

What tool did you use for reading PIC1887K90 ?

[jomberykaso]

file is bad

[junmab]

I read this PIC 18F87K90 with PICKIT3 and MPLAB X IPE.
I can easily see the km in the EEPROM, but i have no idea how to write it back without erasing the program memoery.
Does any one have an experience or software to work around with PICKIT3 programmer that allows to write the EEPROM only (without the program and configuration byte).
I could do that with the PICKIT3 programmer software but this software does not have the 18F87K90 in it's list of MCUs so i had to use the MPLAB X IPE software, but as i said, this software
does not let me write just the EEPROM.
I hope i was not too confusing :)

And PK2 ? Add all parameter with editor software...
If need i question pk2 specialist

I don't have PICKIT2.
What do you mean with "add all parameter with editor software..." ?

Pickit2 dont have 18F series.....Only pickit 3 have ............. send me the eeprom data.

The km is easy to understand from the EEPROM data. That is not my problem.
My problem is that i am using the MPLAB X IPE to control the PICKIT3 and i don't have the option to write only the EEPROM. It automaticly wants to write the program+eeprom+config bytes...
The reason i use this MPLAB X IPE is because the original PICKIT3 sw does not have the 18F87K90. This sw allows me to choose what memory to write, but as i wrote it does not have the 18F87K90 in the list of mcu it can deal with.

[sv2hqx]

pickkit3 have this option
ipe too

[zckariya70]

Through ur software and MPLAB X IPE to bin, install this software only, no need any support software. This have all mcu numbers what u need Enjoy....:)

I downloaded and installed and read the EEPROM only. I'm not writing yet, because the PICKIT3 reads and writes EEPROM+CONFIG+ID.
I disabled the "program Memory" button.
I also disabled the "erase Before Programing".
Now, before i'll attempt to write, is there a way that PICKIT3 will write only the EEPROM but will not write the CONFIG+ID ?

[gogalv]

and read the EEPROM only.
dump eeprom

No need to disable anything read full data and just edit the eeprom data and write all it will be ok.....................

Dear zckariya70. I wish to thank you for the software you sent. Thanks to it i did the job safely, and i'll use it from now on with PIC controllers.
I would like again to explain that your advise to read and write it fully, is something that you should be careful of.
The program is protected, therefore reading it will show all 00. If you'll write it fully, the program memory will be filled with 00, and it means dead cluster.
That is why it is so important to disable the Program Memory in this software.
Thanks to all who helped. You are all so great.

I asked Pickit2 from a Hungarian expert person, that can be added to this 18F87K90

PK2Device Editor v1.0.0.7

The PK3 use 2 type firmware and PC sw
1.0.0.0
3.10 this works PK2 mode

if need i send fw install file version moving

Thanks f2f2, but i already solved the problem with sw from Zackaria70. Job is done.

[miodeki2c]

If program overwritten with "00", there is no way out so as not to throw the cluster into the trash?

You need to put new good file from other cluster (the same cluster)

[miodeki2c]

[QUOTE = jomberykaso; 4102084] Musisz umieścić nowy dobry plik z innego klastra (tego samego klastra) [/ QUOTE]
Yes, but considering the fact that the program is protected, it cannot be read, the cluster must end in the trash?

HELLO
Dear Zakaria, I hope you will be in the best condition and in the best of circumstances. I liked this topic. It was proposed now on this beautiful program. I have read all the dialogues between you and the brothers. Thank you for your efforts, my friend. I would like you to give me an idea about this program, how it works, what works, and how I can deal with it I wish you good luck :date:

[mitachi]

So i download he Zakaria software and disable the program memory, i read the eeprom and change the km, then write it and now the cluster is not working, only ABS is blinking and nothing happend anymore? Its dead? I try the same thing with the original file and still the same.
I disable the program memory writing, but i think it still crushed the cluster?

I wrote about exactly this danger. There is more to pay attention to. It can be a first reading for everything.
Program;EEPROM;CONFIG
config bits read CPD active or inactive
2nd READ only EEPROM save file
eeprom correction
NExt in menu check Programmer..... Clear memory buffers on ERASE need OFF!
if only eeprom write then no ERASE all memory

If mcu full clear then need other MCU repair

[mitachi]

From where i can find MCU repair? Can someone send file to rewrite it?

[f2f2]

Mcu Code protect big problem. If erase program in most cases there will be no replaceable file... other crash dash mcu out solder and in solder

[gcelettronica]

hi friend i need you can send me ?

[gcelettronica]

hi friend can any help me for change this file pic 18f87k90 kymko thank

old is 84217 new 30232 thank

[Diagcar1]

Here try and report,

[gcelettronica]

hi friend i was wrong i need 8426km please forgive me

[Diagcar1]

Here.............

[gcelettronica]

Here.............

hello friend I can't try because I changed pc and I forgot to remove erase all mcu in settings now I'm in the shit can you help me to restore this instrumentation? Only the abs light comes on

[Diagcar1]

If you errased all I think you cant solve it.
