gyro数据相关

Dear Customer:

For AF/AE/Fd modules, data is got in by function like CAFIOUtil::PopulateGyroData(), then filled to below param, which will be used for AF algorithm.

m_AFOutputGyroValue.pAngularVelocityX[index] = pGyroData->x;

m_AFOutputGyroValue.pAngularVelocityY[index] = pGyroData->y;

m_AFOutputGyroValue.pAngularVelocityZ[index] = pGyroData->z;

m_AFOutputGyroValue.timeStamp[index] = pGyroData->timestamp;

For EIS, data is got from following data

ChiNodeWrapper::FNGetData
