Basic setup of W6100

Question

I have followed all the info I can find online, but I still cannot make my W6100 (on WIZ610io) work properly. I tried with and without the io6Library. Expand the tabs to see each version of the process. Steps with io6Library Download this repository as a .zip and extract it. Create a new project in KEIL uVision. Set up the MCU using CubeMX. Copy over the source code in main.c from the example repo into my new uVision project, but changing the SPI handles, GPIO pins, etc. so that they match with my MCU (STM32F407VGTx). Change all instances of printf to sprintf followed by a call to HAL_UART_Transmit so that it will work and I can see the print output over UART. Copy the io6Library files and configure uVision to use them. Make sure everything compiles. Plug in the WIX610io (power, ground, MISO, MOSI, SCK, CS) and UART serial connection (Rx, Tx) to the board, and plug an Ethernet cable into the W6100 and the PC. Run the code. It runs, hooray. The printout looks like this: < W6100EVB Hal Driver Loop Back TEST!! > interrupt mask: 02 VERSION(200) = 4661 Mac address: 00:08:dc:57:57:20 IP address : 192.168.0.13 SN Mask : 255.255.255.0 Gate way : 192.168.0.1 DNS Server : 168.126.63.1 LLA : FE80:0000:0000:0000:0208:DCFF:FE57:5761 GUA : 2001:02B8:0010:0001:0208:DCFF:FE57:5761 SN6 : FFFF:FFFF:FFFF:FFFF:0000:0000:0000:0000 GW6 : FE80:0000:0000:0000:0200:87FF:FE08:4C81 Great, it seems to be working. The debugger shows the code looping over the loopback_tcps function, and the state of the Sn_SR register is 0x14 (SOCK_LISTEN). Now it’s time to connect to that socket. On the PC, I go to Control Panel > Network and Internet > Network and Sharing Center > Chang adapter settings > double click “Ethernet” > Properties > select “Internet Protocol Version 4 (TCP/IPv4)” > Properties > select “Use the following IP address:” > enter 192.168.0.13 for “IP address” and 255.255.255.0 for “Subnet mask” > Ok > Ok > Close Then open up Hercules SETUP Utility. Go to the TCP Client tab. Enter 192.168.0.13 in the Module IP field and 5001 in the Port field. Click Connect or Ping. It times out . Steps without io6Library Write the code shown at the bottom of this post under the CODE tab. Open the code in Arduino IDE. Upload the code to a Sparkfun RedBoard. Connect the WIZ610io to the RedBoard (power, ground, MISO, MOSI, SCK, CS). Connect an Ethernet cable between the W6100 and the PC Run the code. The output is the following: W6100 reset. Chip ID is: 0x610 (should be 0x610[0]) Version Number is: 0x4661 (should be 0x4661) Network config set. Socket sizes set. Socket 0 opened. Socket 0 listening. Waiting for connection... looping looping looping ... Try the same steps as above (steps 9 and 10) It times out . The interrupt never fires, and so the code says looping forever. I must be doing something wrong, but I don’t quite know what. I have tried using a router in between the PC and the W6100, I have tried using both straight-through and crossover cables, I have tried connecting to the…

Update: I have now used Wireshark to view the packets being sent by the Hercules Setup Utility, and it seems that Hercules only sends the requests over wi-fi, not Ethernet. When I click “Connect” in Hercules, Wireshark shows a connection packet coming through on the wi-fi monitor, but not on the Ethernet monitor… I can’t find any info on how to fix this. Update2: I was able to send raw Ethernet packets through my Ethernet adapter by using a Linux VM and inspect them with Wireshark. I will try to see if that can trigger the interrupt in my Arduino version. Update3: Sending raw packets to the correct MAC address (11:22:33:aa:bb:cc in this case) and the correct IP address (192.168.1.99 in this case) still did not trigger the interrupt on the W6100 for the Arduino version.

7 of Steps with io6Library: What you saw through serial is the W6100’s information. IP address mean the W6100’s IP address(192.168.0.13) and it is no the IP address of PC. Therefore the 9 of Steps with io6Library is set incorrectly. If you use dynamic address(DHCP), you have to use DHCP the W6100 and PC. You have to download the arduino ethernet library for W6100 and Of the branch, the W6100 branch value should be apply and download. This link is arduino ethernet library for W6100 : W6100 Arduino Ethernet library

In this page , Then, set your IP address and subnet mask as same as WIZ550io’s IP address and subnet mask. This comment mean that same network area. And If WIZ550io and PC set the same IP/subnet mask, they can’t communicate. obtain an IP address automatically” should be set in the network adapter options, but then how do I know what the IP address is? You need IP address for communicating. If you want to know that How do I set my computer to DHCP? If yes, you refer this link : Change TCP/IP settings

I tried using the new Arduino Ethernet library with a router in between the W6100 and the PC. The router’s IP address is 192.168.1.1, which I set as the DNS address and default gateway address. Using the Chat Server example, I was able to use Telnet to connect to the W6100. I then printed out every register in the W6100 by using VDM to read them all out and looked at the differences between the register state from my code and register state from the example code. I noticed that the subnet mask in the example was set to 255.255.0.0, whereas I had mine set to 255.255.255.0 instead. After changing to the correct subnet mask, I am able to get the interrupt triggering in the non-library code version. However, I am still confused as to why the subnet mask has to be 255.255.0.0. As for the IP address and DCHP, I still don’t understand because I assign an IP address to my device, but then shouldn’t the DCHP re-assign it another address? I think I should read more about subnet masks and about DHCP. Update: using 255.255.255.0 actually still works, but in my header file I had these lines: // NETWORK LOCK #define NETLCK_LOCK 0x3A #define NETLCK_UNLOCK 0xC5 // CHIP LOCK #define CHPLCK_LOCK 0xCE #define CHPLCK_UNLOCK 0x00 which is backwards from how it is supposed to be. After fixing this issue, the registers are set correctly. The correct assignment looks like this: // NETWORK LOCK #define NETLCK_LOCK 0xC5 #define NETLCK_UNLOCK 0x3A // CHIP LOCK #define CHPLCK_LOCK 0x00 #define CHPLCK_UNLOCK 0xCE

Hi, I have Arduino MKR Zero Board and W6100 MKR- Ethernet Shield. I am interfacing both using SPI connections and using Latest Wiznet Ethernet Library but I am unable to ping the Ethernet Shield. I am using MOSI, MISO, SCK and CS pin too. What Ethernet Library should I use for W6100 if there is any? Please guide. Regards, Najeeb
