课程名称：使用 W5500 在 STM32 上实现嵌入式以太网 IoT 应用 课程概述：W5500 是一款极佳的芯片，可以为嵌入式系统添加以太网互联网连接。与 WiFi 相比，以太网在工业自动化中更受青睐，因为它更可靠且安全，无需长时间等待连接访问点或频繁断开连接。W5500 来自 WizNet，内置 TCP/IP 协议栈，这意味着我们可以使用计算能力和内存非常有限的微控制器 (MCU)。您无需在 MCU 的固件中集成复杂的 TCP/IP 协议栈。许多 TCP/IP 协议栈（如 lwIP）需要实时操作系统（RTOS）才能运行，这使得软件开发有些复杂，因为开发者需要熟悉 RTOS 编程。您只需从 WizNet 网站下载一个简单的驱动程序，并将其移植到 STM32，然后开始开发。它提供了类似 BSD 套接字的 API，用于 TCP 和 UDP 通信。我们将编写一个简单的 TCP 客户端，并使用我们的客户端向服务器发送文本消息。通过这部分内容，您可以确定您的硬件和软件设置是正确的，然后可以继续创建使用 HTTP、REST 和 MQTT 的高级项目。对于 MQTT，我们将使用 Paho MQTT 客户端，这是一个免费和开源的 MQTT 客户端。我们将将 Paho 集成到我们的 STM32 平台中。那么，您还在等什么？快来加入我们吧！立即报名！
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.So what are you waiting for? Lets get started! Enroll Now!
