# sim\_home\_switch(9)

Home switch simulator

## NAME

sim\_home\_switch - Home switch simulator

## SYNOPSIS

**loadrt sim\_home\_switch \[count=*N*\|names=*name1*\[,*name2...*\]\]**

## DESCRIPTION

After tripping home switch, travel in opposite direction is required (amount set by the hysteresis pin). A pin (index-enable) is provided for use when **\[JOINT\_n\]HOME\_USE\_INDEX** is specified to reset the I/O pin **joint.N.index-enable**.

## FUNCTIONS

- **sim-home-switch.***N* (requires a floating-point thread)

  ## PINS

- **sim-home-switch.*N*.cur-pos float in**

  Current position (typically: joint.n.motor-pos-fb)

- **sim-home-switch.*N*.home-pos float in (default: *1*)**

  Home switch position

- **sim-home-switch.*N*.hysteresis float in (default: *0.1*)**

  Travel required to backoff (hysteresis)

- **sim-home-switch.*N*.home-sw bit out**

  Home switch activated

- **sim-home-switch.*N*.index-enable bit io**

  typ: connect to joint.N.index-enable

- **sim-home-switch.*N*.index-delay-ms float in (default: *10*)**

  delay in msec to reset index-enable
