 		 #158825 - Problens in I2C
Responding to: ???'s previous message
Hi,

I inspected the mi2cstatus variable, seaching why my I2C doesn't work. I put a function, in the i2c_transfer_finished(), to transmit the mi2cstatus var through serial.

In the main program, I put the functions:

uart_init();
i2c_init(AT24C256, 0);
EA=1;

and trying to receive:
i2c_receive(AT24C256);

I discover the answer I2C is 0x04 (in the i2c.h from CA, 0x04 is I2C_ERROR!).

My I2C communication doesn't work.

What can I do to solve this problem ?

thanks
