hi,
As I just observed, your roll angle is computed in the inverse direction by this MPU6050 lib.
I compared your values with the values I get from my CMPS11 IMU, and also compared it by this chart:

according to both references,
rolling counter-clockwise (to the left) it's negative,
whilst rolling clockwise (to the right) it's positive there.

By your MPU6050 example it's other way round as far as I see.

I have no idea how a PR works, I just use github to download files and libs. But eventually it's not already verified about this issue or failure, I just came upon that by comparing 3 different code references: so who is right or wrong?
