The MQTT protocol is an essential key element in today’s Internet of Things (IoT) field, providing core technical support for efficient and real-time data transmission. Currently, projects offering MQTT capabilities are mainly concentrated in traditional, existing “out-of-the-box” IoT device management platforms, lacking sufficient attention and exploration of the underlying MQTT protocol implementations. However, we firmly … Read more
The previous two articles discussed the basic decomposition process of the MQTT protocol. This chapter mainly discusses the implementation of specific messages. Since the message handling specifications are quite similar, we will introduce the Connect and Publish messages, which are relatively complex in the MQTT protocol. Understanding the protocol analysis of these two messages will … Read more
JZGKCHINA Industrial Control Technology Sharing Platform The core factor behind the success of EtherCAT is its open-source nature, with global PLC manufacturers contributing to its development. In this process, CODESYS plays a crucial role in the success of Beckhoff’s EtherCAT. Just like a high-performance engine needs a chassis, EtherCAT also requires a software platform like … Read more
In the early stages of learning, the hardest part is finding learning materials, so today I recommend a repository that summarizes embedded open source projects. This article carefully compiles some embedded-related resources, including but not limited to programming languages, microcontrollers, open source projects, Internet of Things, operating systems, Linux and more. These materials are continuously … Read more
