Ethernet Wiz W5500

[pspeirs]

Hi All,

I've been playing with the W5500 click board using the example from libstock. I can see the code working as expected, however I want to server up html pages and am having problems working that out. Has anyone used this chip as a html server?

Cheers,
Paul

So a little more information. Using the eth wiz click example, the main code posted below I can get an echo back using a tcp terminal. When using a browser, I can see the sentsize = buffer size but nothing is rendered.

Could it be that the socket is getting closed or am I missing something.

With hundreds of views on this post in 24 hours surely someone out there has some ideas

Cheers
Paul

     20150514:
       - initial release (FJ);
 * Description:
     This code demonstrates how to use ETH WIZ click board.
     Board sends echo reply to UDP packets on "PORT_UDP" port.
     Board listens to a connection request on "PORT_TCP" port. After connection is established, it sends echo reply to incoming TCP packets.
 * Test configuration:
     MCU:             PIC18F45K22

 * NOTES:
     - Place ETH WIZ click board in the mikroBUS socket 1.
     - Put power supply jumper (J5) on the EasyPIC7 board in 3.3V position.

With 768 views, the lack of assistance is frustrating compared to what it was a couple of years back, especially from the Mikroe team.

[filip]

Hi,

I apologize for the late reply, could you tell me which MCU are you using ?

Regards,
Filip.

[pspeirs]

Hi Filip,

Thanks for the response.

I'm using the EasyPic V7 board with the 18F46K22 running at 20MHz. The WizNet W5500 click is in socket 1 as suggested. Using an app called "Multi Terminal" I can send and receive characters in TCP and UDP. I've included the zipped fileset which contains a few more files I've been playing with.

I need to be able to use an then integrate a small web server into my project for configuration of various settings, I tried the ENC28J60 but found the transmit buffer was way too small for my needs.

Hi Filip,

Did you have any luck with the request.

Regards,
Paul

[filip]

Hi,

I didn't have success, so I will contact our developers to see if they have any idea.

Regards,
Filip.

[pspeirs]

Hi,

Your help is much appreciated.

Kind Regards,
Paul

[pspeirs]

Hi Filip,

Did you have any luck with the devs? I think most of the code is there, probably isn't a huge task to add the necessary bits.

Kind Regards,
Paul

[filip]

Hi,

Well, since this request is rather custom code request (as you concluded that the click board is actually working, TCP and UDP),
I'm not in liberty to push our developers much, as there are task with higher priority at the moment.

Of course, I will update you when I have any information from them.

Regards,
Filip.

[pspeirs]

OK appreciate that, please note also that I'm happy to contribute to the development if that is an option. Otherwise I'll wait to hear back.

Cheers,
Paul

[pspeirs]

Hi,

Any news on this issue fro Mikroe as it is holding up my development work, or with the over 1600 views surely someone would have come across this issue and solved it.

Cheers,
Paul

[pspeirs]

Hi,

I've now managed the solve the issues and I can now server web pages correctly, redirect, etc.

Cheers,
Paul

[filip]

Hi,

I'm glad that you managed to solve this.

Can you please post the solution here, so that other user can get this working ?

Thanks in advance.

Regards,
Filip.

[pspeirs]

Considering I paid for the development when Mikroe were too busy to look at their halfway coded solution I'd be happy to share what is a comprehensive solution in exchange for an STM32 dev board.

Cheers,
Paul
