NAME

       sim_pin - GUI for displaying and setting one or more HAL inputs

SYNOPSIS

       sim_pin [Options] name1 [name2 [name3 ...]]

       Options:
         --help (shows help text)
         --title title_string

       For bit items, the name may include a /mode= specifier:
           namei/mode=[pulse | toggle | hold]
           (default is toggle)

DESCRIPTION

       HAL boolean items (bit) and numerical items (u32, s32, float) are supported.

       If the named input is a numerical type, the GUI displays:

          Entry  Entry widget for value or a valid Tcl expression.
          Set    Pushbutton to set new value from Entry (or use <RETURN>)
          Reset  Pushbutton to reset to the value present on initiation

       If  the  input  is  a  bit  type,  the GUI shows a single pushbutton that is controlled by
       radio-button selectors:

          mode=pulse   Pulse input to 1 for each pushbutton press
          mode=toggle  Toggle input for each pushbutton press
          mode=hold    Set input to 1 while pushbutton pressed

       If the bit item mode begins with an uppercase letter,  the  radio  buttons  for  selecting
       other modes are not shown

NOTE

       LinuxCNC or a standalone HAL application must be running

       A named item can specify a pin, param, or signal.  The named item must be writable:

         pin    IN or I/O (and not connected to a signal with a writer)
         param  RW
         signal connected to a writable pin

USAGE

       sim_pin  can be used interactively from a shell command line or started automatically from
       a configuration INI file.
