Question [NSHIELD 52-RE] Advise of basic steps
Posted by: Byrpierce.3nec - May-14th-2021, 08:20 AM - Forum: Software - Replies (1)

Hello everybody,
I would like to ask you if you would advise me the basic steps regarding the use of I-NUCLEO-NETX.

I-NUCLEO-NETX

I have already prepared PROFINET communication scenario in SYCON.net and communication model in Simulink for Speedgoat target machine. Problem is, that i'm new to these shields for industrial network and basicly i don't know what to do. As a host I'm using board from STM, specifically STM32F429ZI-Nucleo. I have installed STM Cube IDE 1.6.1 with actual NETX-CUBE-Expanstion_1.3.0.1, where is already some DEMO project for PROFINET.

What I need is prepare own code and configuration for NSHIELD 52-RE and i would like to send 2x float (temperature, humidity) and receive 2 configuration bytes.

SYCON.net configuration:
NETX_52_RE_PNS_V4.2.0.x
Module Output 4 bytes
Module Output 4 bytes
Module Input 2 bytes

I think, that i need export this configuration and upload it on Shield.

Shield blinks red LED on COM1 - No data exchange.

Thank you very much for any help in this topic.

Best regards,
Byrpierce.3nec


  Several questions
Posted by: rlahnsteiner - May-6th-2021, 11:48 AM - Forum: Hardware - Replies (3)

Hi, I just purchased my first NetPI RTE and have several questions:

1) Can I access the network settings in the Control panel from a node-red-app? 
2) How can I write/read data from a USB media from Node-red? (Tried to install usbmount, but didn't install.)
3) How can I change the display resolution? I get 640x480 only, unable to change it.
4) How can I set the Chromium-Browser to Kiosk-mode?

Thanks for your assistance.

Best regards

Robert


  netFIELD OS Kernel Version
Posted by: Irina Grinberg - May-2nd-2021, 02:16 PM - Forum: Software - Replies (7)

Hi Armin,
I see that the current version of Netfield OS is based on Linux Kernel version 4.19.71.
According to this thread - https://github.com/raspberrypi/linux/issues/3226
there is a UART issue fixed in Kernel version 4.19.97.

We encountered this issue using Raspbian OS on NetPi, and indeed updating the kernel solves it.
My question is - how often is Netfield OS updated with the latest kernel changes?


  Recovery for empty SD Card
Posted by: Dipro - April-27th-2021, 04:23 PM - Forum: Software - Replies (3)

Hi,

I hab an issue with my SD card and it wasn't readably anymore. Now I can't use the recovery USB stick to restore my netpi. How can I create a new SD card with a base image, so that I can use my netpi again. Is there any base image I can use for that?
In other threads I read that the netpi OS is specific to each MAC adress of the netpi. Is there any other recovery method besides an USB stick with the recovery tools?

  netPI RTE 3 and Profibus
Posted by: Kanasak - April-23rd-2021, 09:38 AM - Forum: Hardware - Replies (2)

Hi everybody,

We have several netPI RTE 3 devices for a project and the customer is asking me if the netPI can communicate with PLC on Profibus protocol. I know the communication chip is a netX 51 SoC and I saw on Hilscher website a Profibus Slave firmware for netX 51 (product NXLFW-DPS, 7427.420). Is this firmware loadable into the netPI netX Soc ? And is there a linux driver available to use it with C ? Sample code would be also very appreciate Big Grin  !

Thanks all !

  Bluetooth testing
Posted by: DSongra - April-23rd-2021, 08:43 AM - Forum: Software - Replies (6)

Hello Armin,

I am testing netPI RTE for Bluetooth. Ipad act as another Bluetooth device to communicate & exchange data with netPi RTE.

I have installed the Node-red docker container from (https://hub.docker.com/r/hilschernetpi/netpi-nodered) & added Bluetooth related setting as below.

   

 
I can get a scan result in the Bluetooth node (attachment result). but after deploy & then inject it got to connect for 1 second then disconnected & then it gives an error (attachment error). complete debug error message (debug error message).


Br,
Devendra

  communication cycle as EtherCAT slave
Posted by: tad - April-15th-2021, 12:23 PM - Forum: Software - Replies (2)

Dear Armin,

Once I apply the following container to netPI and make it an EtherCAT slave.
hilschernetpi/netpi-netx-programming-examples

In this case, is it possible to reliably pick up the data coming from the EtherCAT master with a communication cycle of 2ms?
I think the host OS (Linux) on netPI is not a realtime OS so that I can't judge whether netPI can receive the data of 2ms cycle 100% surely.

Thank you very much for your advice.
Best regards,


  activate Ethernet cifx0
Posted by: Christian_Rau - March-23rd-2021, 10:37 PM - Forum: Software - Replies (3)

On page 44 of the German user manual for the NetPi it says: "In the delivery state, the Ethernet interface cifx0 is deactivated. Section "Activate Ethernet interface cifx0" (see below) describes how to activate this interface. "However, how cifx0 is activated is no longer described below. How can I now activate the interface so that I can configure IP routing according to page 52?


Addition: I have newly installed version 1.2.2.0.


  Touchscreen with DVI Port
Posted by: Dipro - March-23rd-2021, 09:37 PM - Forum: Software - Replies (1)

Hello,

I'm trying to use the hdmi-container (https://hub.docker.com/r/hilschernetpi/n...sktop-hdmi) together with an touchscreen. The touchscreen unfortunately has only a DVI or VGA port. The touchscreen was plugged in during the container deployment, but there isn't any signal on the screen.

On multiple Raspberry Pi forums and tutorials I've seen some workarounds using the config.txt to add certain settings. Can this be done on a netPi? How else is it possible to use a display without a HDMI port (on a different screen with HDMI this was no issue)?

Thanks in advance

  Access to RTC from my own container application
Posted by: tad - March-19th-2021, 02:20 PM - Forum: Software - Replies (1)

Dear Armin,

netPI has a RTC so that I suppose Linux (host OS) always has accurate date & time from RTC.
That means I don't have to set date & time to Linux at the bootup of netPI.

Then, I would like to know how to get/set current date & time from/to RTC by my own container application, please.

- I should open Control panel of Web GUI if I need to set date & time, right? 
- I can just use 'hwclock' command from a guest OS (a container) to get current date & time, right?
- I don't have to access RTC directly via I2C interface, right?

I am not familiar with C/Python/,,, so I may be asking an incomprehensible question.

Thank you very much for checking my understandings above.
Best regards,
