Hi ,gilperon Do you know why is the variable DMPpacketbuffer never initialized? because nobody here knows ,and I cant find any information about this variable. mike

Hi Vivek, wow ,I didnt notice that before. But after few hours , I find the datasheet of the MPU-6500, and it has the addresses the library defines,but not all of them are the same registers as library defines. So, keep going , thank you for your reply.

I am really a newbie about this sensor. I use the library MPU6050 written by Jeff Rowberg, the header file defines the registers' address from 0x00 to 0x75, but the datasheet shows the address not continuously from 0x00 to 0x75, for example I want to know how does the function setXGyroOffset() work, and it says the register RA_YG_OFFS_USRH 's address is 0x15,but I cant find this register from the datasheet. Second problem is the packetSize = mpu.dmpGetFIFOPacketSize() from the example of MPU6050_DMP6, it says the default is 42bytes,but I cant find any information from the datasheet about the packetsize,could any one explain this? Really appreciate .

Hi, I just read the i2c & mpu-6050 for several days and I am really a newbie. If my arduino robot car moves in constant velocity,how can i know my displacement in a time(e.g. 5s)because mpu-6050 only gives acceleration data?
