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.
