Whatever else is wrong, you definitely need to loadusr the component before you try to set any of its pins. The pins won't exist until it is loaded.

-W should mean that the loadusr command waits for the component to be ready before continuing.

When you say "Didn't work" what error message do you see?

This is what i got now.

in my_mill.hal file

Code:

loadusr -W pokeys

net all-home pokeys.0.in-2 => halui.home-all

in postgui_call_list.hal file

Code:

setp pokeys.0.devSerial 38163

If i use terminal with:

Code:

halrun
halcmd: loadusr -W pokeys
halcmd: setp pokeys.0.devSerial 38163
halshow

Pokeys response to the switches i installed before. Check, pokeys works.

I close terminal.

I start Linuxcnc (Gmoccapy)

Emergency butten ---> Machine Enable.
Go to settings ---> button Halshow

I go to watch en selecting the pins from the pokeys.

No response from my pre installed buttons.

Eny one got an example how it should look like?

Why do you have a different order of execution in your "real" HAL than when testing?

Where did you get the pokeys HAL driver from?

I followed the installation from this topic (page 1)

After i continued reading this topic, on page 5 i read this:

juanelo1221 wrote: Ok,I think I've got it!
Yesterday I was testing the system. thinking first in the update I moved my debian wheezy to debian jessi and afterwards tried to update linuxcnc.Everything seemed right until I tried to open my-mill then a linuxcnc error appeared. I thought the issue was because I had created the file in the older version so I created a new one but had no success. Desperate and a little upset I made an afresh installation of debian wheezy, I updated cnclinux and was able to open up the file.
I went back to do all the steps Fixer stated from page 1 and connected the Pokeys in windows to know the serial number. In the file my-mill.hall I wrote loadusr pokeys, ran the linuxcnc and was now able to see the pins. I shut down linuxcnc and now in my-mill.hall I wrote pokeys.0.devSerial 66258 save file and try to open linuxcnc send me an error:

Code:

Debug file information: . ./my-mill.hal:7: parameter or pin 'pokeys.0.devSerial' not found

I change the code loadusr pokeys and pokeys.0.devSerial to custom.hal and show me an error, if I put the loadusr pokeys in my-mill.hal and pokeys.0.devSerial66258 in custom.hal linuxcnc run fine, and pokeys.0.err are false and pokeys.0.alive start blinking. Is this procedure correct?

I tried to use estop with pokeys to test but i did not get it work, in custom.hal I wrote net estop-ext <= pokeys.0.in-52 it dont send me errors and in HAL configuration the pin 52 show :
Owner Type Dir Value Name
7 bit OUT FALSE pokeys.0.in-52 ==>estop-ext

Thank you so much for your help, have a nice day.

My apologizes for my lack of language. I try my best to explain my issue. I really hope to get it to work.

Erik

Is it possible that you need to recompile linked to a different RTAI system?
From the starting post:

Code:

gcc -Wall  -Os -g -I. -I/usr/include/libusb-1.0 -I/usr/include -L/usr/lib/ -L/usr/lib/arm-linux-gnueabihf/ -lPoKeys -lusb-1.0 -I/usr/realtime-3.4-9-rtai-686-pae/include -I. -I/usr/realtime-3.4-9-rtai-686-pae/include -I/usr/include/i386-linux-gnu -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=0 -fno-math-errno -funsafe-math-optimizations -fno-rounding-math -fno-signaling-nans -fcx-limited-range -mhard-float -DRTAI=3 -fno-fast-math -mieee-fp -fno-unsafe-math-optimizations -DRTAPI -D_GNU_SOURCE -Drealtime -D__MODULE__ -I/usr/include/linuxcnc -Wframe-larger-than=2560 -URTAPI -U__MODULE__ -DULAPI -Os  -o pokeys ./pokeys.c -Wl,-rpath,/lib -L/lib -llinuxcnchal

There are quite a number of explicit references to a specific RTAI path in there.

No, forget that, it has already been shown to work on your current system.

Try adding

Code:

show pin

after the "loadusr pokeys" line in the HAL.

Also, start linuxcnc from the command-line (command "linuxcnc") and paste all the output here.

Works like a charm!

Thank you so much for the support!

A overview how it works for me.

in my_mill.hal file

Code:

loadusr -W pokeys

show pin

# --- HOME-ALL ---

net all-home pokeys.0.in-2 <= halui.home-all

# ---CYCLE START ---

net program.run pokeys.0.in-0 <= halui.program.run

# ---CYCLE STOP ---

net program.stom pokeys.0.in-3 <= halui.program.stop

Home-all works also without going to the home tab.

in postgui_call_list.hal file

Code:

setp pokeys.0.devSerial 38163

i got also three 10K potetiometer to use as feed, maxvelocity and spindle override.
How could i get this to work though?

Well, that's weird.

"show pin" was only meant as a way to get some output to check if the pin existed. It wasn't meant to fix the problem.
Does the problem un-fix if you take the "show pin" back out again?

I don't see any reason for "setp pokets.0.devSerial" to need to be in the postgui call list.

It looks like some sort of race condition, which is odd as the -W should wait for completion.

Do you have the potentiometer values appearing and changing in HAL?

I could try to remove 'show pin' and check if its realy that issue.
Another thing, those arrows are they have a function? Does it make a difirents how you insert them? ( <= or => )

About those potentiometers, i set them as analog input with the pokeys software.
I have to check how i can see values insted of I/0 dots.
