Software implementation of TWI Slave
Just anyone who might be interested, I am using peter fleury's software library to define my chip as master to spare one of my hardware bus to set up the chip as a slave.

Yes, each sensor can only have two addresses. I should take a look into "i2c Multiplexer". Thank you.

Each bus has two MPU sensors already. All the buses on the xmega are occupied and I'm looking to output the data through I2C to another device.

Sorry ki0bk, I'm not sure I get you question. I'm new in i2c communication. But currently I'm using an xmega to play a role of slave in the I2C communication. However, I ran out...

TCC0_CNT and _delay_() don't match
I believe the timer function is running with a frequency of 2MHZ meanwhile the  delay function is with 32MHZ. That's why I'm not getting a correct value.

Problems when programming Xmega128A3U by AVRISP XPII
The "Read Signature" command work fine.  I just fixed the problem. My supply voltage was too low. The chip required a voltage of 3.3 to program I guess. That's how i get it...
