Getting errors on Raspberry Pi 3

I tried running one of the examples and get ioctl_set_msg failed:-1

Using hardware: PWM

Which PI version do you use?
What is the exact hardware version?

Try one of the other branches / pull requests

beside that channel 0 might be a bad idea - try some other channels. especially if you run a installation with UI some channels should be avoided.
