LinuxCNC on Raspberry Pi 5

sudo ping -i 0.001 -c 1000000 -f 192.168.1.1

This was pinging my router, for about 15 minutes, and I did not get a failed packet, no lockups.

unable to get gpio to work on Raspberry Pi 5 using latest image

Category: Advanced Configuration

It does work, 2 users have had a couple of users have confirmed it.
I've also confirmed myself that loading of the driver as given in the docs also works.

Taking GPIO8 out of the input list allows the driver to load correctly. Which makes sense as GPIO08 as well as GPIO07 seemed to be claimed.

section lifted from gpioinfo
"GPIO7"   "spi0 CS1"  output   active-low [used]
"GPIO8"   "spi0 CS0"  output   active-low [used]

Commenting out spi out in /boot/broadcom/config.txt "fixes" the issue.

THC with Beckhoff EL5101 and THCAD2 => encoder signal loss

Category: Plasmac

Maybe the EL5101 can say when it doesn't have a good reading, or something along those lines. Obviously check cabling.
It seems you get zero Hz as frequency, that's a unique signal, THCAD always give some hundred/thousand of Hz.
Maybe some hal trickery to hold the last good value while frequency is zero. An own component perhaps.

Yes, a real time component could monitor the voltage and add a delay before it drops the voltage sent to plasmac. The moving average would do something similar. Say it averaged 1000 readings ( 1 second), it would take 1 second before it fell all the way to zero.

From your halscope plot, please let me know how long it lasts for.

I would try at the THCADs 1/32 divide ratio

(The 1/1 ratio has relatively short pulse widths = 0.5 usec
which might be too short for the EL5101)
