15.2 Introduction to Interrupt Processes When an interrupt occurs, it first passes through the IRQ register. When the IRQ register detects an interrupt, it sends an interrupt signal to the Nested Vectored Interrupt Controller (NVIC) of the central processor. When the NVIC detects the interrupt request, it suspends the corresponding interrupt service routine (ISR). After … Read more
Introduction The I2C (Inter-Integrated Circuit) bus is a two-wire serial bus developed by PHILIPS for connecting microcontrollers and their peripheral devices. It is a widely adopted bus standard in the field of microelectronic communication control. It is a special form of synchronous communication, characterized by fewer interface lines, simple control methods, small device packaging, and … Read more
1. Nature of the Problem: The Fatal Impact of Disconnections on IoT Systems The 4G module, as the “nervous system” of IoT devices, directly determines the reliability of the data link. According to industry statistics (2024 GSMA report), 30% of IoT device failures stem from communication module anomalies, with frequent disconnections ranking first. The consequences … Read more
