Today, we will discuss interrupt handling in ARM Cortex-M. In embedded systems, interrupts are the core mechanism for achieving real-time responses. Imagine if there were no interrupts: • When a button is pressed, the system might be busy with other tasks and miss the response. • Incoming communication data might be lost due to untimely … Read more
In communication design, considering the flexibility of the protocol often leads to designing protocols as “variable length”. An example is shown in the figure below: the communication protocol frame of the Ruimi LoRa terminal. If a system receives the above “variable length” protocol frame, there will be a challenge—how to efficiently receive and parse it. … Read more
