Can Atmel ATTINY84 read I2C without adding any program or module?

Question

I am recently connecting a gyroscope(L3G4200D) to ATTINY84,however, the gyroscope is using I2C and the ATTINY84 is using USI, as a result, I have some problem doing programming. I am using Arduino Uno to be the ISP, and I have connected the two wire of gyroscope to SDA and SCL pin on Attiny84 but it still doesn't work. Does anyone have any solution?

Answer 2

Solution is in using right library which do software I2C. get https://github.com/svoisen/TinyWire library, connect 4 wires ( VCC, GND, SDA, SCL ), do not forget 2 pull-up 4K7 resistors to SDA/SCL. that's all.
