The W5500 module gave me a lot of satisfaction while learning about it. The issues that I had to face along the way were alien to me, therefore I was twice satisfied that I managed to explore the “secret” network knowledge. So thank you for the W5500 module for broadening my horizons of knowledge 🙂 I paved the way, so I invite you to a great adventure with the W5500 Ethernet module from Wiznet . In the article I will show you how to easily handle the W5500 module using PIC32MM . In practical classes we will establish communication via UDP protocol between our W5500 module and the local PC. On the way, we will use network tools such as WIRESHARK to eavesdrop on the network. In addition, I will show you how easy it is to send UDP packets from the LINUX system . The article will be an introduction before continuing the topic, the culmination of which will be the full implementation of communication with the selected Cloud. I hope I can make it happen. This is the goal of my meeting with the W5500 module .
