Project with a Wiz550io

Question

Hello, I will use a Wiz550io in a project and I have some questions since I’m quite new with it and with Ethernet in general. If my wiz550io is powered (and RSTn is high), I can directly ping it with a pc if my pc got an IP adress in the same network, right? (192.168.1.XXX) ? (theoretically) I got a board with SPI communication, it provides the clock and everything. What do I have to configure if i want the simpliest way to send datas using the Wiz550io/ethernet to read it with a computer ? (like “sniffing” ethernet port of my computer ? Using UDP or TCP? If so, what do I have to configure…) Does someone can help me with that or redirect me to some help? Thanks in advance and sorry for possible broken english.

Dear Vermu I think you can test WIZ550io with Arduino platform easily. Please refer to the following link. Wiz550io , Arduino due , Mysql_connector (arduino ide) WIZ550io Unfortunately I don’t have Arduino DUE. So I will explain for Arduino UNO. First of all, prepare Arduino UNO and WIZ550io module. Connect Arduino UNO and WIZ550io module like below. Arduino UNO pin<->WIZ55io pin 3.3V<->3V3D GND<->GND 13<->SCLK 12<->MISO 11<->MOSI 10<->SCSn RESET<->RSTn [image] I recommand to use ioShield-A. [image] Execute Arduino IDE. Select Arduino IDE Menubar->Sketch->Include Library->Mange Libraries… Search Ethernet2 library by string. Install Ethernet2 l… Thanks.

I don’t have any arduino, isn’t it possible with a PC?

If you have only WIZ550io, you cannot use Ethernet. You must have the platform or MCU board like Arduino UNO. PC1Arduino UNOWIZ550ioPC2 Or MCU HostWIZ550ioPC1 Or PC1WIZ550S2E-232-EVBPC2 Thanks.

As i said in my first post : “I got a board with SPI communication, it provides the clock and everything.” It’s a custom board with a FPGA on it, I aim to use a microblaze or picoblaze on it

jim · Answer

Actually, I don’t know a microblaze or picoblaze. When I search that, I found there is the bus interface. (I don’t know if I’m right.) If you want to use the bus interface instead of SPI, refer to W5300 chip. wiznet.io W5300 | WIZnet Co., Ltd. W5300 is a Hardwired TCP/IP embedded Ethernet controller that enables easier internet connection Thanks.

Picoblaze and microblaze are softcores of Xilinx. You can use SPI on it (xilinx provide a code they developped where the FPGA is an SPI slave but you can make it a SPI master)

Hello, I just have a question for the clock i’m generating, it’ll be faster if it’s a yes, if it’s a no, the SPI will be just a bit slower. Does the clock the SPI master provide has to be 50% duty cycle? I’m doing it with a picoblaze and it’s quite easy to generate a SPI clock where duty cycle <50% but the low and high state are both > 6ns (like the SPI datasheet of the W5500 suggest) (I’m not working from scratch and the code which was provided by xilinx to make a SPI master for a flash memory is making a clock but not 50% duty cycle)
