MPU6050 FIFO Buffer

Using Arduino Sensors
1

Hi,

So I am doing a project where I need to get acceleration data from an IMU. The catch is that it must read from a FIFO Buffer because the project I am doing will be computationally intensive and I can't loose readings while preforming those computations. So I tried the MPU6050 with FIFO via it's DMP. However, this requires an interrupt (and others that did it without one, theirs's always froze) and I can't be doing interrupts while doing my "computations".
Does anyone know a reliable way to get FIFO data from the MPU6050 without the use of an interrupt or know another alternative IMU that also has a FIFO buffer?

Thanks everyone for their help!!

Hi,
What controller are you using?
Have you looked at the ESP32, I gather you can run two cores.

Hi, in the main project I will be using a Particle Boron based off of the nrf52840 (same cpu on arduino nano 33 ble). So that won't be an option. Thanks anyway.

For those trying to find an answer/solution, an alternative to the MPU6050 would also work!

I am looking at the MPU6050 library by ElectronicCats: https://github.com/ElectronicCats/mpu6050/blob/master/src/MPU6050.cpp

and I have a question:

in line 1794, does the getMotion6 function get those measurements from the internal FIFO buffer of the mpu6050?

Thank you in advance!
