  1. Hello everyone.
    I'm quite new to Arduino and i2c so please bear with me even if my questions may have an obvious answer from your point of view.
    Looking at the example of 6 axis MPU 6050 I'm trying to wrap my head around some programming decision that was made, specifically:

    1) Why do we run while loop 

    while (!mpuInterrupt && fifoCount < packetSize) {

     inside the main Arduino loop() instead of just simply running single interrupt flag and fifoCount check each iteration of the loop(), is that to catch new data package as absolutely soon as possible?

    2) Why do we use interrupt at all, can't we just check getFIFOCount() and if > packetSize - retrieve data. I've modified the example to do just that and it seems that data is still fine, nothing borked e.t.c. I might be missing the whole point of using interrupts here, please clarify this for me if possible.

    Thanks in advance!
