please help me.

You try read with Pony programmer.Originally posted by tatillo View Post
Pony better read FIS than upa.:smash:
If you have experience in electronics ...
You can make the interface (only part of the I2C) for 15 min and solved this. :thumbsup:Comment

sorry but what programmator i must use ?
i have only upa.
(You can make the interface (only part of the I2C) for 15 min and solved this) have you some scheme and list component ?Comment

All write here
PonyProg - Serial device programmer
the two images
You need to use from the base only part that works for I2C (not made whole base).
Follow the wire and see that necessary for the I2C, you interested only SCL,SDA and GND, nothing more !

sorry but wher i must attach gnd, and i must take gnd from pin 5 r232 or diode zener, the radio must power on and attached to 12v or not ?
sorry but i'am not expert.
Ma sei italiano ?Comment

Radio yes +12v normally,Originally posted by tatillo View Post
and 3 wires to the interface, GND SCL SDA
It is all man. :boxing_smiley:
not italiano.Comment

sorry if i disturb again but i do not understand about gnd,
step 1: i connect scl and sda with cable from radio to programmator
step 2: i connect 12v+ and gnd from adjustable power supply to radio cable +12v and gnd
step 3: power on radio
step 4: i open software and i try to read dump with many test 24c01 24c02 24c32................ until find the right eprom
question: the gnd that you told me i do not know where attach and what is the part right of must take or connect gnd, i must attach from radio to programmator or from programmator to radio, if is right programmator to radio, where is the poin in the circuit of the radio for attach gnd ?
excuse me again and tanks for all.Comment

If you make interface (Bravisimo :hurray
, first tested it on some old carradio with 24cxx.
Gnd interface connect with GND car radio. Use ohmmeter and see nearest point (nearest GND to scl sda).Comment

ok i hope read dump
I tried with multitito to read 24c16,32,64 and i have more dumps.
dumps(24c16,24c32,24c64), now i attach dump 24c64
i hope that you find the code, if you do not want find, please explain to me how ca do it.
