Bad Connection!!!???

[kima]

I use schematic and hex from this site and pic16f628-20/P. My box is recognized

from software (nk_fl105) like v01.02-5001 but when I connect my phone and push

button F1 ( or other ) I have bad connection message. The phone is 3210.

I try to change parallel port setting but nothing.

I use 8MHz quarz.

HS on
Power on
Mclr on
other off

Best Regards !!!

Hi Kima!!

Please try putting 2 extra capacitors on each leg of the crystal.....U should have used a 8Mhz ceramic resonantor...with build-in capacitors.

Try that and post ur result.

Hi,

I made a different version of the box.
Just changed/added some resistors and it works.

Problem is that the power of your PIC is becoming to low when the Mbus line
is pulled down. Then the PIC stops working and gives ' bad connection' on your
screen.

If nothing seems te work, remove the protection diodes also from your MBUS line.

Should work then.


(mail me if you want it, because attachment is not allowed !??)

I fixed "bad connection" but now I have message "Unsuported FLASH model"

when I try to flash the phone.

He recognize box and the phone but flash dont work.

See attachment!!!

Read the manual Dejan give you.

You need to make a directory with the name NK_info and put all your tia's
inside.

Then it should work
