The following code will set a HAL pin to True whenever a step is sent from the Axis GUI. You will need to work out how reset the pin either via you component or a timer...
EDIT: The code was modified after Andys suggestion and has been tested. All you need to do is set axisui.step-activated to 0 from your component.
Code:
# this will create a HAL output pin named axisui.step-activated
def user_hal_pins():
comp.newpin('step-activated', hal.HAL_BIT, hal.HAL_IO)
comp.ready()
# this function replaces the task_step function in Axis
def hijacked_step(*event):
# this is the original code from the task_step function
if s.task_mode != linuxcnc.MODE_AUTO or s.interp_state != linuxcnc.INTERP_IDLE:
o.set_highlight_line(None)
if run_warn(): return
ensure_mode(linuxcnc.MODE_AUTO)
c.auto(linuxcnc.AUTO_STEP)
# turn the HAL pin on
comp['step-activated'] = 1
# add the new function to the TclCommands
TclCommands.hijacked_step = hijacked_step
commands = TclCommands(root_window)
# point the menu item to the new command
root_window.tk.call('.menu.machine', 'entryconfigure', '5', '-command', 'hijacked_step')
# point the toolbar button to the new command
root_window.tk.call('.toolbar.program_step', 'configure', '-command', 'hijacked_step')
# point the keyboard shortcut to the new command
root_window.bind("t", commands.hijacked_step)
This code needs to be in either
.axisrc
or the file specified by
[DISPLAY]
USER_COMMAND_FILE in your ini file.
