About I2C problem.

I have a problem with using the I2C memory. When the command for a write is given to the microcontroller, it hangs. What should i do ??

Even there's a problem with read command.

Please Reply.

There's something wrong with the slave then. If you issue a 'write' to a device that physically isn't there, then it wont hang. instead you'll get 0xFF when you do a read. If you write to a device that is not working right, then your master PIC can hang.

The Code Examples forum has plenty of examples of both Master and Slave pics.
