*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)

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

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

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

Example for INI file usage:

[APPLICATIONS] DELAY = 5 APP = sim_pin \
halui.machine.off/mode=pulse \
ini.traj_arc_blend_enable \
motion-command-handler-tmax
