Course Description

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 a 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.

The course goes slow, but covers details pretty well. Avinash explains why things are done, instead of just do this. Additionally, if you have problems or questions, Avinash responds very, very quickly. Much appreciated.

The course content is very useful to understand the TCP/IP communication and MQTT via W5500. Moreover, I was able to use MQTT with STM32F407 + W5500 Lite. Thanks for the also support which was a very useful part in terms of feedback

By Mario Benedetto on 11/28/2024

Very interesting and valid course. The instructor has explained the contents well and provided useful information to solve a particular case "TCP Server".

w5500을 처음 다뤄볼때 도움이 되는 강의입니다. 하지만 MQTT를 활용하기 위해서는 이 강의만으로는 부족합니다. (24.09 기준) 앞으로 강의가 추가될 것 같지만, MQTT를 활용하려면 직접 ioLibrary_Driver를 살펴봐야 합니다. 다소 부족함은 있지만 시작하는 단계에서 방향을 잡는데 도움이 되는 강의입니다.

Very well explained course and given with step by step execution of code. Its a must course of students who want to learn embedded Ethernet using W5500.

By Abhijit Gangoly on 7/10/2024

Content is good, but presentation needs to be improved. Some newer updated are in the supplied material of some classes, but not in the video itself. Recommended to update the respective videos as well.

By Anthony Tam Ying Yan on 4/11/2024

Excellent course! The explanation is very clear and details. Besides, this course nearly covers all network application such like tcp, datagram, mqtt, https... etc.

Avinash G, i learned a lot from your website, now i am looking forward for a lot more from you on this particular platform. Thanks for this amazing course.

By Ángel Molina Egea on 11/25/2023

From my point of view the quality of the course is fine, very recommendable if you want to know how to work with the w5500 chip in a fast and easy form.

By Eric Wang on 11/19/2023

So far so good. I like this course as the tutor made a good explanation on every details of the technologies and all the code so far works well. I am new to the ethernet programming, this course can guide me go through the technology. Thanks.
