faster RTDX time while enabled

now that I have learnt that the problem with RTDX comes when it is enabled, I know that I should only be enabling for a short time.

There is a noticible effect on the motor when I log at 10k, but not when I log at 1k. How about 5k? sample_time_rtdx = 0.0002.

Seems to log okay with no noticible interruption of the motor but the hall effect plot is pretty crappy still.

another guess at speed would be 7 HE cycles in 0.1 sec = 70 HE cycles in 1 sec = 70/8 hz = 8.75 = 8.75*60 rpm = 525rpm
