I checked in 1.7, the ITG3200 low pass filter setting was 10Hz, and now in latest dev it's 256Hz. This makes copters very sensitive to vibrations. I recommend to change it back to 10Hz or at least 25Hz.
(recommended code change in sensors.pde)
Code: Select all
i2c_writeReg(ITG3200_ADDRESS, 0x16, [b]0x1B[/b]); //register: DLPF_CFG - low pass filter configuration & sample rate -- value: [b]20Hz[/b] Low Pass Filter Bandwidth - Internal Sample Rate 1kHz
This change made my very twichy quad to fly as smooth as slik.
