PnCConf questions

I have a 5i25 connected to a 7i77 which has VFIELD and VIN. There is nothing connected to the 7i77 or to P2 of the 5i25.

1) On the Mesa Config page tab the firmware (7i77x1) reverts to prob_rfx2 each time I open PnCConf. It doesn't seem to change any of the settings. Any ideas?

2)On the Mesa Config page what are I/O Connector 2 and 3 tabs? I assume they are not the 5i25 connectors since P2 is unused when using a 7i77 daughter board.

3) On the I/O connector tabs do the Num(bers) have any significance?

4) On the I/O Connector 3 tab I selected XYZA and spindle encoders (and PWMs on SS1 tab). I expect to see all encoders going to P3 of the 5i25. If I run LinuxCNC the red LED on the 7i77 changes to a green flash and the hm2 section under dmesg is:

Encoders 3,4,5 are not shown, should they be?

That is probably enough daft questions for one day!

The number of encoders shown in dmesg is correct.
each _muxed_ encoder instance supports 2 actual encoders

If you show the encoder HAL pins and parameters you will see
that there are 12 encoders available ( if you enable all of them).

Chris not around?
Anyone game to answer my other questions?

Sorry I some how missed this:

1) That sounds like a bug. What version are you using?
2) connector 2 and 3 are indeed the 5i25 connector numbers.
3) Yes the numbers are the HAL number (component number)
4) What you need to understand is the 7i77 daughter board passes the encoder signals to the 5i25,
so the encoders really are on the 5i25's P3 connector but you connect to them using the 7i77's connections.

I also see that since you selected 7i77x1 that you won't get the help page that might have explained the numbering system a bit.
selecting 7i77x2 and deselecting half the encoders and half the serial channels should then allow that page to show in the help page.

This deselction is what 7i77x1 does automatically - it's actually the same firmware.

Thanks Chris.
1) 10.04 with 2.5.1
2) OK
3) OK
4) Understood

Chris,
1) My Help Page is the same after 'Accept components changes' whether the 7i77x1 or 7i77x2 is chosen.
When choosing the 7i77x2 everything not used is listed as Unused Input/Output/PWM Gen under SS3/4 so there is nothing to deselect.

2) From Help Page under Config Tab
'The help page output tab will show the firmware PIN file,
which shows the default components, their channel number
and their Component number'

and this is the Output tab:

<?xml version="1.0" ?>
<int-pncconf>
<property name="version" type="float" value="1.000000"/>
<property name="always_shortcut" type="bool" value="False"/>
<property name="always_link" type="bool" value="False"/>
<property name="chooselastconfig" type="bool" value="True"/>
<property name="machinename" type="string" value="my_LinuxCNC_machine"/>
<property name="mesablacklist" type="eval" value=""/>
<property name="customfirmwarefilename" type="string" value="~/Desktop/custom_firmware/firmware.py"/>
</int-pncconf>

It doesn't seem to be a PIN file.

3) The info 'Generated by PNCConf...' which appears just before hitting OK to start LinuxCNC is confusing as it states 5i25 with 34I/O pins and 7i77 firmware.
Here's a sample:

P3-17 8 (0 Muxed Encoder 0) x-encoder-a
P3-19 9 (0 Muxed Encoder 1) y-encoder-a
P3-23 11 (1 Muxed Encoder 0) z-encoder-a
P3-47....

These P3 numbers seem to relate to a 5i20 not a 5i25

4) There seems to be no way inside PNCConf to change the 7i77 Mode from 0 to 1 ( loadrt hm2............sserial_port_0=10xxxx).

Is there a way to do this in the custom.hal?

No sorry you must edit the main HAL file.
PNCconf only supports mode 0 at this time.
