Unlock [W5500-EVB-Pico] and explore the underlying layer of Ethernet. The 4th issue of Digi-Key Electronics' Follow me is here!
[Copy link]
"Follow me event" is a one-year "Learn technology from technology experts, complete tasks and get cash back" event initiated by DigiKey and EEWORLD. There will be 4 sessions in 2023. Every 3 months, technology experts will recommend development boards/instrument kits with strong playability and learnability, and take everyone to actual operation.
Participants who complete the target tasks according to the live broadcast and the board introduction within the specified time can get a cashback on the order fee (the maximum cashback amount is 300 yuan, you can choose one of the two methods [company labor] and [JD card + red envelope]). After evaluation, those who complete the task well will also receive additional rewards.
The activity aims to help electronics enthusiasts learn practical electronic technology knowledge, accumulate DIY experience, and become better together! Come and join the 4th issue of Follow me~

4. Complete the tasks specified in this period
Participants need to purchase the required board W5500-EVB-Pico and complete the following tasks (all are required tasks).
Note: After being shortlisted, you must follow the event regulations and place an order on the Digi-Key official website to purchase the required motherboard W5500-EVB-Pico.
Getting started tasks: build the development environment, BLINK, drive the LCD display to display (if there is no serial port HelloWorld)
Basic Task 1: Complete the initialization of the main control board W5500 (static IP configuration), and be able to ping it using a LAN computer. At the same time, W5500 can ping Internet sites; use packet capture software (Wireshark, Sniffer, etc.) to capture the ping message of the local PC, display and analyze it.
Basic Task 2: The main control board establishes a TCPIP or UDP server, and the LAN PC uses a TCPIP or UDP client to connect and send data. After the main control board receives the data, it sends it to the LCD screen for display (if not, it will be displayed through the serial port print); the interactive message is captured by the packet capture software, displayed and analyzed. (Choose one of TCP and UDP, or operate both)
Advanced task: synchronize time from NTP server (pay attention to the parsing of data exchange format), obtain time and send it to display screen (serial port) for display.
Ultimate Mission (Choose One)
■ Final Task 1: Visit https://www.digikey.cn/zh/resources/api-solutions to learn about DigiKey digital solutions and its API operations, and design a DigiKey electronic component price and inventory monitor that can synchronize and display the price, inventory and other information of specified electronic components in real time.
■ Ultimate Task 2: Use external storage to build a simple FTP file server that can upload and download files normally.
