I2C MPU6050 with I2S problem

[dreamworker]

Hi,

I am running an application that reads the sensor data from the MPU6050 via I2C with @kolban-c++-lib - thanks for the great work!
However I have problems getting stable sensor data as soon as I am using the I2S driver. the application is supposed to play a beep sound (wave-data) when a certain accelerator value exceeded. Both parts work perfectly fine in two cores. But as soon as I start the I2S driver and play the sound in a loop the I2C starts to send randomly wrong data and worse stops after a while for 1000ms and then continues. This repeats as long as the I2S is active. I tried to run both in different cores also both in same loop on one core, there is no change in the behaviour.
I wonder if somebody has an idea?!

Cheers dreamworker

Hi,
if this not problem you can try this library:
https://github.com/jrowberg/i2cdevlib/t ... 32_ESP-IDF

I've added esp-idf. This library has implemented DMP if you need it.

@chegewara: Thank you for your proposal. Unfortunately that didn't help. I seems not to be a direct problem with I2C since getting values works just fine as long as no external I2S device is used. as soon as I start the I2S communication by installing the I2S driver, the I2C messages seem to break randomly with 1000ms breaks. Maybe somebody else came along this problem too?!
