Pokeys_homecomp EncoderSearch / Encoder Arm Topic: Pos_Fb Following errors

It seems to work!!!
The . alive is blinking,
.in-1 works also, the .deb is counting up and restarts every time...
.ain-0 with a poti works also...
and the counter works!!!
 

Big thank to you, Dominik!
Friday I set up a second encoder, I will tell you if all works!

Best regards
Marcel

Hi Matze,

I'm glad to hear that.

do you think we might need to extend that as described in chapter "4.5 Encoder" of www.linuxcnc.org/docs/2.2/HAL_User_Manual.pdf ?

calculating "postion" using parameter "scale" should be a short one.

i can imagine that at some point "reset" might be needed, there is a PK_EncoderValuesSet() which we could use to reset the counter to 0 on pokeys for that task.

for "index-enable" i think it will be not that easy to get the next-pulse directly, maybe i just use the next loop when "counter"-value changed. (as a workaround)

for velocity we would also need to get timers involved which might get a bit complicated, but nut sure if it will be needed at this time.

(i anyway planned to do that on my pokeys.comp on github)

(please note: when doing reset with current pokeyslib it's not yet possible to write/reset single encoder values to device - so i might expect issues depending if some encoders moved between ReadEncoders&WriteEncoders)
 

Hi Dominik,

I think position, scale and reset would be nice to have.

Hey Dominik,

tried it out, the .scale and .position works.
But the .reset dosn´t...
 
(I assume if I hit reset, the .count will be set to 0?)

EDIT:
I think it would be good, if the reset is be done at start of Linuxcnc...
If the last .count valvue was for example 10, at a restart of Linuxcnc it is 10, too...
So for my example to use it for feed-override, it is set at 110% at start of linuxcnc...


Best regards
Marcel

Hi Marcel,

sorry for my late reply. Now i also have my encoder wheel wired to my pokeys57CNC.

i think i found the problem.
(reset at startup is added also)

did you setup this encoder for jog-wheel operation or as position feedback?

Hey Dominik,

thank you for the new file, this works as it should.

I set up the encoder for feed- and rapid-override.
had first a poti, but like the encoder-style with push-button for reset more...

Best regards
Marcel

G'day Dominik (or anyone else who knows their way around pokeys on linuxCNC).

I've tried following the steps on page one of this thread, but keep running into errors at the make step. I have attached an error log to this post. Does anyone have and idea what I am doing wrong?

Thanks, Matt

there are updated instructions, which can be found on page 10.

which usually work as described.
forum.linuxcnc.org/24-hal-components/298...rnet?start=90#162953

it includes Reading of digital and analog inputs.
(my component is extended to also read use kbd48CNC, and basic functionality of PulseEngine, external Relays or OpenCollector outs - but as it is doing this it creates to many Pins if it is just added to an existing HAL-file)

If you review the errors, it is failing during the build process.
I have the same issue.

you get these build errors even if you use the update instructions (page 10)?

i did not have problems so far - but there might be some changes (pokeyslib, linux,...) since i did my last build on that component.


 

PoKeysLibDevicePoKeys57Industrial.c: In function ‘PK57i_SearchDevice’:
PoKeysLibDevicePoKeys57Industrial.c:221:12: warning: implicit declaration of function ‘GetBroadcastAddresses’ ...
 

so it seems that pokeyslib commit "Merge of updated PoKeysLib to public repository"(2022-06-23) includes a change for PoKeysLibDevicePoKeys57Industrial.c, which might cause that problem.
