DevI2C

for many Invense 6/9axis chip，the i2cdev code should work. diff: - Default I2C address, 0x68 or 0x69 depends on your board. - WHOAMI ID, register address 0x75, this depends on 6050/9150/9155, you can find it in the register map doc. - no more, i guess.

try this.

thanks @Jeff Rowberg, new to arduino but this works for me. - Arduino Nano and a GY92/65 board(actually MPU9255 embeded). - baudrate 115200 - D_0_22 inv_set_fifo_rate 0x00 for 200Hz output - Serial.write close. * for now no FIFO overflow interrupts, doing the checking of noise
