Hi there, I am attempting to use an SSD1306 and a MPU6050 together. I am using the U8G2 and I2CDevlib libraries but the devices seem to be mixing each other up. The devices each work seperatly but not together and have different addresses. Does anyone know why this is happening?

Hi there,I am using the MPU6050 and I2CDevlib library to obtain quaternion values from the sensor. This sketch is currently taking up a bit too much memory for my liking and I noticed that there is a 64 byte buffer. Since I am only using one set of data, is there anyway to go into the library and not input the other data such as acceleration and gyro?Thanks

Would anyone be able to explain these general terms about the library? 1. How does the Digital Motion Processing (DPM) within the chip work? What does it do?2. How does the interrupt work? What is it caused by? I have a heavy sketch going on in the meantime (SD card, display, heart rate sensor.etc) in the background. Can it still be used with all these modules without delaying other functions?3. How does the library incorporate quaternions? Thanks Daniel

Hi there, I am trying to use this library with my MPU6050 and Arduino to count steps and it is working great but it is taking up too much flash. Is there anyway to reduce the amount flash this library takes up? Daniel
