Ok, so I am using a gyroscope in order to control the movement of a stepper motor. Everything works fine for a while and does what it's suppose to until suddenly it just stops.
I wrote the values being outputted by the mpu to the Arduino monitor box and I found that the values just stop generating!!!
I have tried putting the mpu on 3.3 and 5 volts on the arduino and this did not help(The mpu is designed for 5 or 3.3 volts-it has a built in resistor).
Does anyone know what is wrong or how I could fix it, I don't see why this is happening.
In what way are you "reading" your sensor - by using any libraries ? If you are using MPU6050 library to read DMP , you;re getting FIFO overflow. Same happended to me and nothing worked. If you're using any Serial.print statements, use highest baudrate avaible. Then, if youre using library from : MPU-6050 6-axis accelerometer/gyroscope | I2C Device Library you can open the file called " MPU6050_6Axis_MotionApps20.h " , go to line no. 305 and modify last value . You'll se a comment uder this value explaining everything. This is called DMP FIFO rate . Make last number bigger and you'll get more time for other stuff in your program. I went as high as 0x63 but it didn't solve my problem so now I'm reading basic RAW values and using Kalman filtering - works perfekt for me
Thank you so much, this helped great. I increased the value in the library to x09 which is sufficient for now, it takes a whole for it to stop reading now but still maintains data.
You can play with this value and see how MPU's response time is changing. To obtain this value, use the formula given in comment and convert it's result to HEX ( you can find plenty online DEC to HEX converters ) .
