Wrong Quaternion Output

[swords001]

Hi, Ferrocen

First of all , I wanna thank you so much for porting the Motion Driver code. In fact, I'm using MSP430 MCU which is supported by the Invensense code. However, the code is quite complicated with USB stuff then I found your ported code. I 've been able to read the data from fifo then the problem come out. If I read the accel and gyro data from FIFO, it'll return corectly but not for quaterion the data

As you can see, The quat[0] and quat[2] are messy while quat[1] and quat[3] are stable. If you have any suggestion, please inform me. I've stuck with it for a month. Thank you in advance
