PLEASE CORRECT MY CODE FOR I2C COPIER

i2c eprom copier

I experiment eeprom I2C Copier with this schematic
**broken link removed**

But verifiying data always error.

please help me....correct my code in attachment, THANKS FOR ALL

i2c copier

I have not looked at your code as this appears to be a programming error.
You will have to check your programmer as it is failing to write to the Micro.

how to find i2c data errors

A PICkit2 or my Junebug can copy I2C EEPROMs.

correct the code

You can find the original project here with source codes.

Brother my code from **broken link removed** but why always verifiying data error,what is problem? u have code valid or u have same schematic project with u code.pls help me brother so i'm dizzy with my project.

code for i2c in basic

I have tried the same code. It is programming perfectly to PIC16F84A. May be your programmer or the Chip has some problem. Good luck

Hello!

I'm not sure about what the PIC does (i.e. if it is a hardware SPI or if you
emulate it with a GPIO). But this hardware seems against the I2C
philosophy.

Basically, the idea behind I2C is that you use only 2 wires and you can have
myriads of devices on the same 2 wires. And this hardware uses 2 different
clocks. This gives you potential strange behaviors.

- The data is common.
- You have 2 clocks A and B.

Suppose you're reading from device A. Device B is therefore idle (SCL high).
If while SCL is idle you change the status of the data (that you are already
using on the other channel), then it will create a start condition. Well, I know
this might not be a problem, but why complicating things that can be simple?

I don't know where this hard comes from, but I would rewire it the regular way:
SDA and SCL are common, and the address is different (for example
device A: A1A2A3 = (0,0,0) and device B (A1A2A3) = (0,0,1)
