dLAN Green PHY eval board II - help

andrearendine — Thu, 11 May 2017 08:03:06 GMT

Hi everyone,

I have two dLAN PHY eval board useful for powerline communication and I'd like to understand better how to programm this board based on LPC1758.

If someone have a detailed documentation (more that the datasheed and manual on the website of Devolo which are very poor writed) or some examples about this board could be great.

I'd like, just to start, to send a paket via PLC e and turn on the LED to the other board.

Thanks

Andrea

Dear Andrea,

devolo provides a new SDK, which is available on github.

GitHub - devolo/dlan-greenphy-sdk: The devolo dLAN Green PHY module is ideal for installation in all IoT-devices. Inclu…

This SDK is under development and there is no MQTT included yet, but it should be easy to start with this software, because it is more structured and FreeRTOS 9 is included. Please checkout the 'devolop' branch for the moment.

Best regards, Tobias.

Hi Tobias,

I'm beginning of this stuff on Devolo so I'd like to have somethig which

explain kind of detail how to start with this board.

I have the board, the debug, the IDE for programming, but actually I

didn't found a guide on how to use this evaluation board. ( how to

connect? how to flash the firmware? how does works the libraries? how does

is handled the HOME PLUG POWERLINE? etc..)

Also an electronic schematic about this could be interesting to have.

Can you help me?

Thanks

Dear Andrea,

there is some information available on the webpages of devolo. Please go to the (german) webpage:

dLAN® Green PHY eval board II - devolo Business Solutions

There, you will find 2 documents:

Datenblatt - some information about Hardware - language is English!
Handbuch - some information about how to get started with the old SDK- language is also English!

I think it is a good idea to start with the bridge mode.

Connect one standard (HomePlug-AV e.g. dLAN® pro 1200+) PLC adapter to your router via Ethernet.
Power the evalboard using the USB plug.
Connect a workstation to the Ethernetport of the evalboard.
Press the PAIR button on both, the evalboard and the PLC plug.
After a while the PLC LED should indicate the PLC connection.
If there is no connection via your workstation you should install the old SDK in bridge mode first. This can be done using LPC-link2 and the JTAG connector.

2nd step is to install the develop branch from github and collaborate with us realizing your idea.

Best regards, Tobias.

andrearendine — Fri, 12 May 2017 14:14:45 GMT

Hi Tobias,

I already have these documents and I already tried the PAIR connection and

I see the LEDs blinking, thinking that the two board get paired.

This don't help me to understand how the comunication between the two

board with powerline communication comes.

For example I want to know how is made the packet (size, lenght,

bandwidth, frequency etc...) , how is sent, what means the the two board

get "paired", how the second board recognize the packet etc.

For my purpose I'd like just to start to send ONE packet from one board

and receive the packet to the other board and BLINK the USER LED. How ?

Thanks.

Dear Andrea,

I can understand your idea, but HomplugAV greenPHY is a fixed protocol which is used for example in the world of eMobility and building automation. This insures that the communication is always compatible to standard HomePlugAV wall plug adapters. You can not change this parameters, because they are encapsulated in the QCA7000 chip.

Please use google with these keywords "QCA7000 HomePlug greenPHY" and you will find the datasheet of the PLC chip which is used on this evalboard.

Since we don't have the chance to change any of the PLC parameters, we have to understand, that there is a IP connection between all the PLC devices used. You can regard this connection as a substitute of a traditional ethernet wire connection.

The idea might be to setup a TCP/IP connection to another host. A common approach is to use MQTT, but a webinterface is also used by some of our customers. There you can add for example the functionality to turn of the USR LED on or off using LPC GPIO commands ().

Dear Tobias,

thanks for the support.

Actually I have read the QCA7000 HomePlug greenPHY and also the datasheet

of QCA and LPC uP.

However, I need something practical about the evaluation board.

So you confirm that the only way to use the PLC is bridged with Ethernet?

Is not possible to send a paket, rightly modulated using the pre-set-up

HomePlug greenPHY libraries? I don't want to change the standard but to

use the standard.

My example is easy: SEND PKG (with PLC HOME PLUG), if the packet is

correctly received so RECEIVE PKG --> turn on USER LED.

Is possible?

Thanks,

Hi,

of course it is possible to transmit and receive selfmade packets, but I strongly advice to use the IP standard. The best way to commit IO information is to use MQTT. An example is available in the main branch of the SDK, which is actually reworked in the devolop branch. A new example and also new documentation will be available soon.

Best regards.

You don't have to use the ethernet interface. You can link the PLC interface to the (webserver)-application of the LPC1758. That can be done with pre-processor command in the master branch. In the develop-branch there will be a connection between the ETH, the PLC and the webinterface.

Dear Andrea,

I agree that the documentation of the new SDK is poor at the moment, but we are working on that as soon as the wanted base functionality is available in the new SDK on Github. The old SDK will be dropped from our homepage then and we will provide the official link to github from the page very soon!

This week we implemented a valid MAC address implementation for all the interfaces. You don't have to enter a static MAC for each greenPHY product anymore, which was criticized by some of our customers. You can share your engineering with us by working with the development branch. If you want to use all the features which are described in the SDK-Word-document you have to use the old SDK, but I would like to ask you to share your ideas within the new branch!

Hi Tobias.

is possible to connect a spectrum analyzer to the board and evaluate at

least the bandwidth used?

I tried to follow the datasheet which explain how to set the jumpers in

order to use the coax cable for PLC but connecting with spectrum analyzer

I don't see nothing.

Can you help me?

Dear Andrea, since HomeplugAV greenPHY is a fixed standard, you can not change the frequency range which is used in the SDK. This is 2 - 30 MHz. We call this range "low band". Non greenPHY HomePlug AV products are also using the high band additionally, which goes from 30 to 68 / 85 MHz.

To measure the frequency range you can use J4. Remove all the jumpers from J8 and place them to J7. J5 and J6 should also be closed. If you want to use J3, please remove the jumpers J5 and J6, too.

Best regards, Tobias.

Re: dLAN Green PHY eval board II - help

andrearendine — Wed, 17 May 2017 08:36:45 GMT

Thanks,

but my question was another.

Is possible to see with the spectrum analyzer the OFDM of the 2-30MHz

signals?

Further:

1) How many pkt the two board sent?

2) What is the power of the single pkt?

3)What the two board "says" between each other?

Sorry if I ask but I really need to undersand.

Thanks

You can regard the devolo eval board as a perfect platform to investigate the Homeplug AV greenPHY technology. All the PLC parameters and details are the same since a greenPHY chip is the purpose of this evaluation system. Any additional functionality, such as handling of sensors and actors, is controlled by the LPC1758 host processor.

Dear Andrea,

for any technical questions the people from codico can help you. You can find our partner here:

DEVOLO - dLAN, dLAN WiFi and dLAN GreenPHY available at CODICO

The can also help you starting your project using green PHY. If you are thinking about large quantities or bigger projects you can contact me again. I will check if we can takeover your project with my team then.

Best regards, Tobias.
