[Update Links] Embedded Ethernet on STM32 Using W5500 for IoT Applications | Udemy

W5500 is a great chip to add Internet Connectivity to Embedded Systems over Ethernet. Ethernet is a preferred communication method in Industrial Automation because it is more reliable and secure than WiFi. No long-waiting time for connection establishments to access points or frequent disconnections.

The W5500 from WizNet has inbuilt TCP/IP stack that means we can use a MCU which has very limited computing power and RAM. You don’t need to integrate complex TCP/IP stacks on your MCU’s firmware. Many TCP/IP Stacks like lwIP requires and real time operating system in order to work. Which makes writing software a bit complex because the developer needs to be familiar with RTOS programming.

You only need to download a simple driver from WizNet’s website and port it to STM32 and then start your development. It provides BSD socket like API for TCP and UDP communication.

We will write a simple TCP client and send text message to a server using our client.  After this you are sure that your hardware and software setup is perfect and can move on to create advance projects using HTTP, REST and MQTT.

For MQTT we will use the Paho MQTT client. Which is a free and open-source MQTT client. We will integrate Paho in our STM32 platform.
