Thanks for any advice - Mike UPDATE: Reran the experiment using a 1 second delay with similar results which I am uploading as a PDF images along with the Temperature profile.
Was wondering if you had any experience with this and point me in the right direction to correct it in the code, also based on the data is it worth it to put in the correction or just put a test in let it warm up first until a set limit. I can attach the graphs if you are interested. I have only looked at 19-23degC region and not tried to heat it up yet. It also appears that the temp affects the accel readings and the gyro readings (raw) to different degrees depending on the axis (gyro or accel). From what I can see from dumping the 6050 temp the readings don't really stabilize until about 22degC. One of the things that I noticed is that when I first start it takes quite a while before I can get stable readings from the MPU-6050 and the cube programs not to go nuts.

I am using the FreeIMU code written by Fabio and as I was going through several of the comments I came across his todo list which brought me to the your's and his discussion on temperature compensation for the ITG-3200 board. Hi Jeff First I want to say thanks for all the libraries not just the MPU-6050, been using them with a several different standalone sensors and combo boards. Serial.print("temp deg C: ") Serial.println(temp) Serial.println("Getting Die Temperature") * Temperature reading in 16-bit 2's complement format Serial.println(accelgyro.testConnection() ? "MPU6050 connection successful" : "MPU6050 connection failed") Serial.println("Testing device connections.") it's really up to you depending on your project) (38400 chosen because it works as well at 8MHz as it does at 16MHz, but join I2C bus (I2Cdev library doesn't do this automatically) AD0 low = 0圆8 (default for InvenSense evaluation board) specific I2C addresses may be passed as a parameter here for both classes must be in the include path of your project I2Cdev and MPU6050 must be installed as libraries, or else the. Arduino Wire library is required if I2Cdev I2CDEV_ARDUINO_WIRE implementation This was modified from Jeff's MPU6050_raw.ino example:
Here's another way to access the temp using Jeff's library. The scanner picked up the magnetometer on the 9150 but not the 9250. Also, ran a i2cscanner on the 9150 and the 9250.
#Merlin project serial driver#
After going through the register maps (89), the motion driver software I set up the self test option which the board failed - i checked it against the 9150 which passed. Ok - came to the conclusion that it is a bad chip and nothing I am doing. Also, getting the accel and gryo data seem to be working fine.Īnyone have any suggestions or experience with this issue? I have tried also disabling mastermode and enabling bypass but still does not work. For reference I am using a CJMCU-117 breakout board that I got over ebay. I have gone through all the possible addresses 0x0C through 0x0F with the same results. However, when using the same library with a MPU-9250 which has a AK8975 I keep getting a connection failure when using the test sketch. I have successfully used the AK8975 library with the MPU-9150 which according to the data sheet uses the ak8963 magnetometer.
