Hi @tommylight, thankyou for your insight.
Now i want to expand my inputs and outputs in raspberry pi 5, can you suggest me how to expand my i/o and if there is any solution can you also tell me how to configure HAl

No don't use a hub.

Linuxcnc-rio is awesome, with a single WT32-ETH0 and a direct cable connection and inexpensive FPGA you can do 4 axis easily and way more.

Awesome used all of elovalo bits to setup an Rpi5 with Pineberry NVME hat, works great.

Can you tell me how to configure HAl and ESP32 if I have to build it for just 1 axis?

Using ethernet hub or switch will add a lot to network latency, so it might not work at all, even if everything else works.
Never tried with a hub, but i do have a switch that works with Mesa boards for days without issues.
Still, i never use a switch on production machines, the risk is to big.
-
Network hub = old, any packet sent to any pc wired to it will be sent to all connected PC's.
Network switch = new, any packet sent will be sent only to the PC with the IP address contained in that packet.

in principle, yes,
but you would have to build the hal component in such a way that the ethernet packets are sent and received in parallel,
otherwise it takes too long.

EDIT:
but since udp is used, this can lead to collisions.
maybe send with minimal delay and then wait for the responses

Hi Linuxcnc community, 
I have installed OS in raspberry 5 and Instead of using IO expander I want to use individual ESP32+W5500 for every motor and generate step pulses. If this is possible please help me with the steps in achiving it.
Refer the image below and get what I want to achieve

Thankyou

I working also on 2 other new boards:

1. 3Axis adapter-board with NEMA17 drivers for the iceBreaker Devboards 


2. own FPGA-Board with ice40uP5k and 6Axis as Raspberry-Hat (hope it works ):


both can be build, flashed and connect directly from the RaspberryPi via SPI

 

Hi, i was solving issue with raspberry pi 5 with guys at etherlab, and from my understanding 1ms or 1kHz ethercat cycle is limit for genetric driver. You can get faster cycles when using native drivers like e1000 or igb for intel based ethernet cards.

I was just posting that but then got distracted.
I feel that too many are ready to jump to the latest kernel without really testing.

Seems to be a kernel issue, to many PC's having the same issue, i though this was already fixed by using new kernels.

Forum member Kam visited with a new (old stock) 7i96, got the same packet loss problem.
Tried Windows laptop and Linux laptop, with different cables, all fail.

I note that my install shows as LC2.9.1, not LC2.9.2 as listed in download page.

Replaced LC2.9.2 (1) SD card with a new SD card fresh Imager burn of my old image of LC2.8.4, SUCCESS.
2950 packets for 0% lost.

Both the LC2.9.2(1) and LC2.8.4 were official downloads.

LC2.8.4 loads and opens AXIS.
But still grappling with the Custom Hal to get my E-Stop control working.

Basically back to where I was prior to trying to get WiFi operational.

Now, some more investigation of why my LC2.9.2(1) fails.

Stay well,
John.

pncconf in master supports the 7C81

To use older pncconf with the 7C81 you can make
a configuration with similar hardware (stepgens PWMgens etc)
 and then change the driver name in the .hal file
and card name in the .ini file.


So for example to make a simple step/dir setup
you could choose a 5I25 and prob_rxf2
 then change the:

 loadrt hm2_pci xxxxx

 line in the hal file to:

loadrt hm2_rpspi xxxxx

and the

CARD0=hm2_5i25.0

line in the .ini file

to

CARD0=hm2_7c81.0

 

Hello,
Thank you for your help. I have managed to enable SPI. 
sudo mesaflash --device 7c81 --addr /dev/spidev0.0 --spi --readhmid, now shows that the card is present.
I probably will update to another Pin-configuration for the Mesacard.
How can I use the hm2_rpspi driver? I wanted to build my machine config with the  PNCconf  Wizard and then modify the .hal and .ini files for more things which are outside the capabilities of the Wizard. 
Maybe someone can give me a push in the right direction?
I a have little experience with LinuxCNC and Linux in general.
Also I have used xrdp remote client to access the PC headless and it is giving me trouble. If I install it it works fine, but when I restart the setup the screen shows some distorted mess of pixels. Maybe someone has an idea what goes wrong there?
 

Use the hm2_rpspi driver, the other driver will is it not suitable, if it was we could use it with the RPi5.
