• Is it just me, or is Wiznet not working in V77?

  in Interfacing • 9 years, 7 months

  

  Thanks Gordon for the SPI I/F repair and setIP() command update in version 1.78.
  After reset all W5500 registers are 0x00 - OK.
  And, for DHCP with setIP(), the MAC is updated to 00:08:DC:01:02:03 by default if not specified before.
  The 00:08:DC = "WIZnet" and the 01:02:03 is just random to have a valid value here.
  Now, the W5500BoB is working too :-).

  Just one more strange effect - the MAC-Address looks scrambled after a direct change and then read-back.
  WEB IDE:

  >SPI2.setup({ mosi:B15, miso:B14, sck:B13 }) // for PICO + W5500 (Shim)
  =undefined
  >var eth = require("WIZnet").connect(SPI2, B10) // make the Ethernet object
  ={  }
  >eth.getIP() // just read out the start values out of W5500, expect all 0x00 here
  ={
    "ip": "0.0.0.0",
    "subnet": "0.0.0.0",
    "gateway": "0.0.0.0",
    "dns": "0.0.0.0",
    "mac": "00:00:00:00:00:00"
   } // OK, all empty, as expected
  >eth.setIP() // make DHCP
  > Send DHCP_DISCOVER
  > Receive DHCP_OFFER
  > Send DHCP_Request
  > Receive DHCP_ACK // success
  =true
  >eth.getIP() // read out new W5500 address register content
  ={
    "ip": "192.168.111.190", // received IP-Address
    "subnet": "255.255.255.0",
    "gateway": "192.168.111.1",
    "dns": "192.168.111.1",
    "mac": "00:08:dc:01:02:03" // here default address, ..01:02:03, OK.
   }
  >eth.setIP({ mac : "00:08:dc:1e:dc:3c" }) // change MAC-Address here
  =true
  >eth.getIP() // read out W5500 internal registers
  ={
    "ip": "192.168.111.190",
    "subnet": "255.255.255.0",
    "gateway": "192.168.111.1",
    "dns": "192.168.111.1",
    "mac": "00:08:8e:18:8e:2a" // it's different, strange ?!?!
   }
  >eth.setIP() // a new request to DHCP
  > Send DHCP_DISCOVER
  > Receive DHCP_OFFER
  > Send DHCP_Request
  > Receive DHCP_ACK // working OK
  =true
  >eth.getIP() // read out again
  ={
    "ip": "192.168.111.127", // new IP received from Server, OK
    "subnet": "255.255.255.0",
    "gateway": "192.168.111.1",
    "dns": "192.168.111.1",
    "mac": "00:08:8e:18:8e:2a" // still same strange MAC-Address, we can work with that anyway
   }

  I need to check the source codes, but the MAC address is changed into the 'strange' one always in the same way. Also, if I add just +1 to my intended MAC the 'strange' version also become +1.
  => it's not random. I'm OK with that.
  I think something is wrong while Read or Write the MAC-Address register.

  Thanks and best regards, Joachim, WIZnet Europe GmbH

  Hello Gordon, thanks for the answer.
  You can change MAC address at any time. It's just a 6 byte register in the W5500 chip. You can do that also at the WIZ550io Module, if you like to. Of cause not while you have an open=connected TCP Socket, but no problem beside that. A new ARP will be send with next socket opereation, and maybe a new IP address needed from the DHCP-Server, ...

  The Idea with using .setIP() command for the MAC-address change is good.
  I'll try that, maybe you're more quick at that anyway.
  Good luck with the bug fixing and create 1.78 then - best regards, Joachim.

  Hello Gordon and Friends here,
  first af all I like to say Thanks to Gordon for the massive work doing. He is a one man company doing Hardware and Software all by him self. Let's support him as best as we can. Bugs can happen and Gordon will fix is soon. I'm sure.
  I started to add anpother W5500 Module to the Espruino Pico - and encountered same problem :-(
  Please see my setup here:
  Espruino Pico + W5500BoB + RJ45
  So, I downgraded my Pico to Firmware 1.75 and it works, but only 90%.
  Now, I have another Problem that the W5500BoB does not have a pre-programmed MAC-Addresss and IP setup.
  All is ..00:00:00.. and without MAC-address also DHCP can not work.
  The difference is, that the WIZ550io has a small PIC12 on board to pre-config the W5500 in a few ms (at startup) with unique MAC-address and a first static IP ++++
  So with WIZ550io Module it's no problem.
  But how to get the MAC address into the W5500 without that pre-setting ?
  The W5500BoB has only the W5500 chip, and that's empty at the start.
  And, I could not find any command for setting up the MAC-address.
  Solution:
  => I added code into the W5500 driver inside the Espruino's C code - but the 1.77 is not working ... see main topic is all about here. And I don't like to fork from 1.76 or even 1.75.
  I'm trapped for the next few day - I think.
  Please debug the 1.77 and help me to add MAC-address setup into Espruino FW.
  best regards, Joachim

• Sockets and MQTT now on Espruino!

  Thanks Gordon for the nice work on the "Internet I/F".
  The WIZnet WIZ550io Module is available from many sources in EU also.
  Mouser is B2B and very USA focused - TAX, transport....
  But, more and more shops adopt our Modules, but "free shipping" is very often not available.
  Please check: RS, TME, SOS, Lextronic, Watterott, ... or our shop.wiznet.eu

  Hello Gordon,
  sorry I missed your many e-mails - shame on me.
  Yes, we have some (enough) Espruino Boards here and I will set up more tests tomorrow morning immediately.
  If you like we can send you some v1.1 modules tomorrow (with FedEx) - just send me your current postal address by e-mail - you will have them in hand asap.

  Thanks for your nice work on the Ethernet I/F using our Hardwired TCP/IP Chip / Module.
  We will keep track here and fight the Bug, best regards, Joachim.
