NAME

gearchange - Select from one two speed ranges

SYNOPSIS

The output will be a value scaled for the selected gear, and clamped to the min/max values for that gear. The scale of gear 1 is assumed to be 1, so the output device scale should be chosen accordingly. The scale of gear 2 is relative to gear 1, so if gear 2 runs the spindle 2.5 times as fast as gear 1, scale2 should be set to 2.5.

FUNCTIONS

gearchange. N (requires a floating-point thread)

PINS

gearchange. N .sel bit in

Gear selection input

gearchange. N .speed-in float in

Speed command input

gearchange. N .speed-out float out

Speed command to DAC/PWM

gearchange. N .dir-in bit in

Direction command input

gearchange. N .dir-out bit out

Direction output - possibly inverted for second gear

PARAMETERS

gearchange. N .min1 float rw (default: 0 )

Minimum allowed speed in gear range 1

gearchange. N .max1 float rw (default: 100000 )

Maximum allowed speed in gear range 1

gearchange. N .min2 float rw (default: 0 )

Minimum allowed speed in gear range 2

gearchange. N .max2 float rw (default: 100000 )

Maximum allowed speed in gear range 2

gearchange. N .scale2 float rw (default: 1.0 )

Relative scale of gear 2 vs. gear 1. Since it is assumed that gear 2 is "high gear", scale2 must be greater than 1, and will be reset to 1 if set lower.

gearchange. N .reverse bit rw (default: 0 )

Set to 1 to reverse the spindle in second gear.
