// 20100804: Arthur P.: Modified to use user parameter 7 to determine downstep for motorsmoothing 

// with 0 or 1 defaulting to the default -150% first step followed by upsmoothing and

// values beyond that resulting in 50% (2), 75% (4), 90% (10), 95% (20), 97.5% (40), 99% (100)

// downsteps.

// Within timer0.c user paramater 8 is used to activate an external HEF4017 on FC 1.x hardware,

// and/or to set the shutter interval timer in steps of 0.1sec (minimum = 1 sec), by using

// bit 8 (128) as on/off switch, and bits 7 (0..127) for the timer counter.

//                      else tmp_int = 2 * tmp_int - tmp_motorwert[i];                                                              // MotorSmoothing

// Arthur P: the original code allowed the motor value to drop to 0 or negative values

// straight off, i.e. could amplify an intended decrease excessively while upregulation

// is dampened. The modification would still allow immediate drop below intended value 

// but would dampen this. This would still allow for airbraking of the prop to have effect

// but it might lead to less sudden excessive drops in rpm with only gradual recovery.

// 090807 Arthur P: Due to problems with uart.c which still refers to user parameter 1 and 2 and 

// possible timing issues with the shutter interval load, removed the shutter interval functions

// and switched to use of userparam6 for the motor smoothing.

// 091114 Inserted modification into 0.76g source code.

// 20100804 Modified v.0.80d code where motorsmoothing is no longer a separate function.

// Downsmoothing either uses default v.0.7x+ 150% downstep (user para 7 == 0),

// 50% downstep (user para 7 == 1 or 2), or downsteps of x% (userpara7 ==):

// 66.6% (3), 75% (4), 80% (5), 90% (10), 95% (20), 97.5% (40), 98% (50), 99% (100).
