Description

ADIY Pico RP2040 Evaluation Board with W5500 with Ethernet is a microcontroller evaluation board based on the Raspberry Pi RP2040 and fully hardwired TCP/IP controller W5500 – and works the same as Raspberry Pi Pico board but with additional Ethernet via W5500.W5500-EVB-Pico pinout is directly connected to the GPIO of RP2040. It has the same pinout as the Raspberry Pi Pico board. However, GPIO16, GPIO17, GPIO18, GPIO19, GPIO20, GPIO21 are connected to W5500 inside the board. These pins enable SPI communication with W5500 to use the Ethernet function. If you are using the Ethernet function, these pins cannot be used for any other purpose.

The W5500 chip is a Hardwired Internet controller designed as a full hardwired TCP/IP stack with WIZnet technology. W5500 provides Internet connectivity to your embedded systems by using SPI(Serial Peripheral Interface). SPI provides easy connection via external MCU to W5500. The clock speed of W5500 SPI supports up to 80MHz.

Since W5500 integrates the Hardwired TCP/IP stack with 10/100 Ethernet MAC and PHY, it is truly a one-chip solution for stable internet connectivity. WIZnet’s Hardwired TCP/IP stack supports TCP, UDP, IPv4, ICMP, ARP, IGMP, and PPPoE – and it has been proven through various applications over the last decade.

W5500 provides 8 independent SOCKETs to be used simultaneously and 32KB internal memory for data communication. Users can develop an Ethernet application easily by using the simple W5500 SOCKET program instead of handling a complex Ethernet controller. W5500 also provides WOL (Wake on LAN) and a Power Down Mode to reduce power consumption.

Initialization : ADIY Pico RP2040 Evaluation Board with W5500

You must check PHY LINK (0 bit of PHYCFGR) before attempting to make a network
connection using sockets.

Basic Setting : ADIY Pico RP2040 Evaluation Board with W5500

For the W5500 operation, select and utilize appropriate registers shown below.
1. Mode Register (MR)
2. Interrupt Mask Register (IMR)
3. Retry Time-value Register (RTR)
4. Retry Count Register (RCR)

Data Communications : ADIY Pico RP2040 Evaluation Board with W5500

After the initialization process, W5500 can transmit and receive the data with others by ‘opening’ the SOCKET of TCP, UDP, IPRAW, and MACRAW mode. The W5500 supports the independently and simultaneously usable 8 SOCKETS. In this section, the communication
method for each mode will be introduced.

TCP : ADIY Pico RP2040 Evaluation Board with W5500

The TCP is a connection-oriented protocol. The TCP makes the connection SOCKET by using its IP address, port number, and destination IP address, port number. Then transmits and receives the data by using this SOCKET. Methods of making the SOCKET connection are “TCP SERVER” and “TCP CLIENT”. It is divided by transmitting the connect-request (SYN packet). The “TCP SERVER” listens to the connect-request from the “TCP CLIENT”, and makes the connection SOCKET by accepting the transmitted connect-request (Passive-open). The “TCP CLIENT” transmits the connect request first to the “TCP SERVER” to make the connection (Active-open).
