I am using the audio library and 9-dof IMU from Sparkfun . The IMU functions based on the Wire.h library from Arduino. Somehow the AudioOutput I2S has complicits with my IMU. It will force the IMU to stop working after a few seconds. The IMU works just fine after I comment that line out. Any suggestions of what to do? I tried to dig into the audio library but I don't know where to start. Any advice would be greatly appreciated.
Just to give a bit more information. The line causing the problem is :
AudioOutputI2S i2s1;
It is from GUI declaration.
My IMU works for the first a couple seconds and then output a really large number like 63 (usually it is less then 5). It is also able to work if the IMU is in still. I can restart it by software. Once the shake/move the IMU, it will stall at some point forever and I cannot restart by software command anymore.
So I think it is a communication problem. The I2C is parsed wrong or not communicating well. Is it because of interrupts?
