okey clear,


how about limit switch
to which pin it go.. quad A and B ?

You _can_ use encoder pins as GPIO inputs

That is, special _input_ functions can always be used as GPIO
(of course you cannot use the encoder if A or B are used for GPIO)

To any pin that is not used as and stepgen or PWM or encoder.
All of them can be used as inputs or outputs, just set them in hal, like so:

# --- DOUT-00 ---
setp [HMOT](CARD0).gpio.005.is_output true
#net dout-00  =>     [HMOT](CARD0).gpio.005.out
net plasmac:float-switch  =>     [HMOT](CARD0).gpio.005.out
#setp [HMOT](CARD0).gpio.005.invert_output true

OR

# --- PROBE-IN ---
#net probe-in     <=  [HMOT](CARD0).gpio.003.in_not

Those are just examples, edit them to suit what you need.

and the GPIO pin number is represent the FPGA number

in your example u use 3 and 5 ... this number is I\O number (FPGA PIN number)

in my firmware that PCW make... i will use the NONE labled pin
which is 1 3 13 18 20 30

With a parallel port BOB you would use DB25 pins 10,11,12,13 and 15
as inputs, these map into:

So 10 inputs are available as GPIO inputs for limit switches etc

long time since last update

everything works OK... thanks for the big help..
but now i have an issue... and its the last one
the focus i use 4th axis setup
it works ok if i jog it.
but i cant sent the axis to specific command potion without having joint following error
its because the qtpy sent the exact location to the axis.. which generate this error...not ramp to it

so how can i send axis to specific location using halcmd

i cant find solution for this
i want to send a command like in MDI..
i know that from halui i can do it... but is it valid while program is running?

also plasmac probe twice.. how can i make it once

i rework the capacitance sensing

is there any command allow me to test the head follower aka thc
without running programe

by mistake i burn one of the fpga pin.. for encoder A,, but B still ok.. can i use B line instead of A
