correspondence of unused i/o pins to physical connector location?

Category: PnCConf Wizard

If you know what firmware you have on board, eg the name of the .bit file, all you need to is look in the corresponding pin file, if you've downloaded the firmware stuff.

If not you can redirect the mesaflash output to a text file.

Don't mind me I still spend a bit of time using the command line in Linux. Just find it can be a bit quicker at times.

No mate, genuinely impressed, I think I may have misjudged you and would like to extend my apologies.

All The Best

correspondence of unused i/o pins to physical connector location?

Thank you -- I haven't run my own test yet, but I see the correlations in your sample output.

If I were a python or gui programmer, I'd take a stab at adding that info to pncconf. And I suppose I'd probably discover that it's difficult, which is why it hasn't been done. :-)

Seems like there should be an easier way, than by powering up the board you're trying to configure!

I'm impressed mate :)

Yeah I know you're giving your time, much appreciated, but text files are so much easier to search through. especially for something as long winded as dmesg. Anyway it's so much easier than cutting & pasting.....and millions of times better than a photo of a screen.

Cheers

Regarding Ubuntu, off topic a little, but did you hear that a lot of the core utilities they are rewriting as Rust and dropping the old stable C coded ones (I think a lot of origins from Unix days). I reckon Linux might be in for a few rough years.

The mesa manual for your card outlines it all.
the physical pins are generally numbered from 1 but the pin numbers start with 0
 

No, I don't think it does.  It does have that info for the P1 expansion connector, but not for TB1 and TB2.

Spindle keep accelerating was created by vibram

Spindle keep accelerating

Category: Basic Configuration

Hello,

I built my HAL file with bits taken from the forum and for sure sometimes I don't understand everything.
THis results in the current situation where when I run my Gcode, for example M3 S500, the spindle is going faster and faster and never stops
Signal spindle-at-speed is true before running gcode, then it goes false and never go back to true.
My encoder is working properly with the correct number of pulse.
Maybe the near part is wrong but I have no clue if it's the case, and if yes, why ?

Thank you for your help


Here is the spinde part of my HAL file

use grep with dmesg, we don't need the whole output, or if you're going to give the full output attach it as text file, then it can be searched in an editor.
dmesg | grep "parp"
or
demsg > dmesg.txt
or
dmesg | grep "parp" > demsg.txt

And attach the text files.

sudo lspci -vnn
as said I before gives the name (generic) & PCI ID eg like

which is the important bit and what the kernel uses to load a driver.
