Looking at the ha;_manualtoolchange.py file, I see the following:
h = hal.component("hal_manualtoolchange")
h.newpin("number", hal.HAL_S32, hal.HAL_IN)
h.newpin("change", hal.HAL_BIT, hal.HAL_IN)
h.newpin("change_button", hal.HAL_BIT, hal.HAL_IN)
h.newpin("changed", hal.HAL_BIT, hal.HAL_OUT)
h.ready()
So this tells me what pins are created, the only one I am unsure of is the
change_button, can someone explain this one?
I know this seems petty, but I am trying to wrap my head around it enough so I
can teach a few high schoolers what is going on. Or maybe a little glimpse of
how the parts fit and work together. Before I can do that, I need to teach
myself.
My impression is the hal_manualtoolchange component does the following:
a) receives the tool number via hal_manualtoolchange.number pin
b) receives a command to change the tool via hal_manualtoolchange.change pin
c) The component then opens the dialog informing the user to change to tool #X
d) User does the tool change and clicks the okay button.
e) the okay button send signal via hal_manualtoolchange.changed
am I close?
