 		 #158782 - problens with I2C
Responding to: ???'s previous message
Hi people,

I'll be crazy with CA I2C code. It doesn't work. I only receive the status from I2C bus. I know the I2C bus is I2C_OK, but I don't get to read the e2prom.
I put the status from I2C in the serial and the reading from e2prom too. The reading is wrong, because I receive only 0x00. I know what is written in the e2prom.

I wrote code for the callback funtions, but I'm not sure if those will work.

Can I do to start a reading using "i2c_receive(eeprom_address);" ?

How can I do to test the communication with e2prom ?

thanks in advanced.
Jorge
