WiFi Problem on Raspberry Pi

Category: General LinuxCNC Questions

Borrowed a dongle, TP-Link TP-WN722N, from a Forum Member.

Got an external antenna from another Form Member.

Much swapping and shifting around between bench, cubicle and cabled as far from cubicle as lengths would allow.
Dongle, antenna, 4GB and 8GB, power supplies, LC2.9.2 and LC2.9.4, etc etc
The Dongle works fine, Ebay says $15.

Eventually replaced the monitor on the mill with the one from the bench.
SUCCESS.
Even works in the cubicle with door open without the dongle.

Who would have thought !

Suggestions welcomed on what to do with the faulty monitor.
I am in Kingswood if you want to drop by and take it off my hands.

Thanks to all for the help,
John.

Info regarding Index to the Main RPi Thread

Category: Computers and Hardware

The original thread was getting way long, with a lot of info spread out.
Pleas pay particular attention to the hal_gpio stuff, there is a basic 3 axis mill config that works. If you get any errors when thrying to use hal_gpio, unless the error log states "no permission" the issue is a permission error (which should not happen), otherwise it is related to the GPIO pins selected or somethng else. Mostly this occurs when a user attempts to use the SPI allocated pins without disabling the SPI interface.
What I suggest to the RPi users is to bookmark the Index thread forum.linuxcnc.org/38-general-linuxcnc-q...l-images-only#325007 for later reference .

How to design new driver for my own board

Category: Driver Boards

sweet :)

and for the host interface USB?
this will not really work :(
LinuxCNC is a little bit different to other controller like GRBL,
you need a realtime loop between board and host and this will only work with Ethernet/Ethercat/SPI(raspberry) or LPT., not with USB or UART.

If you need almost ready to use Gateware/Drivers for your board, you can look at:

github.com/multigcs/riocore/
(github.com/multigcs/riocore/blob/dev/doc/BOARDS.md)

this is a gateware generator and all the FPGA stuff is written in verilog,
but it use W5500 UDP interface or SPI.
There is also an UART/USB plugin, but only for testing, not for realtime use.

you can take a look on my youtube channel, there are many videos with different FPGA's running RIO:
www.youtube.com/@unixconf/

but i can understand if you prefer to write your own software, it's also fun :)

(SOLVED) hal_gpio: Operation not permitted fault cannot be solved

Category: HAL

The images are setup and no adding users to groups or messing around is needed.
Read the following thread and you'll find a link to GPIO info and a working example.

(SOLVED) hal_gpio: Operation not permitted fault cannot be solved

Category: HAL

Hello to all.
I'm using Linuxcnc 2.9.4 on rpi5 debian bookworm that is installed from linuxcnc rpi5 image.
I have a problem on running my setup.
I tried many things like adding gpio to my user, creating a file 90-gpio-access that is mentioned on hal_gpio manual (linuxcnc.org/docs/devel/html/drivers/hal_gpio.html)

but I failed.

Linuxcnc 2.9.2 and 2.93 images for Raspberry Pi 4b & 5

Category: Installing LinuxCNC

Hi,
The Linuxcnc 2.9.2 and 2.93 images for Raspberry Pi 4b & 5 are
special OS. The menu-config configuration does not have the option for auto login.
 

Rod's the one that has put them together, apart from the RT kernel & the addition of the Linuxcnc packages it's just Debian. Nothing special about the actual OS.

You should be able to set up auto login the same way it is done with an x86 machine as its the OS you are logging into

Hi,

Is it possible to create an auto-login for the raspberryPi in order to create a keyboard less system with gmoccapy?

Category: Installing LinuxCNC

so it's perfect! if I think how much time I wasted with a nuc i3 to improve the latency without succeeding... I need it to tune up some drives that I recovered 2 years ago, now I also have the servos. if anyone knows these maybe they can give me some advice on how to use them in the best way.

That's the easiest way, I think I mentioned that earlier, I like Network Manager as I can turn the wifi off whilst running a job.
