DSHOT600 output low resolution?

Hello,

I am new to ardupilot so not sure if this is an issue or normal operation. I see that the output to the ESCs is incremented/decremented according to RC transmitter input, as multiple of 10s. Eg 1050 → 1060 → 1070 and not 1050 → 1053 → …

That is just the display. The code has full resolution.

No issue here.

Perfect thanx! However what raised my suspicions is that if I increase the throttle slowly I can hear the motors increasing speed in clearly discrete steps.
