SPI is very common in embedded systems, whether in system processors on chips (such as ARM, MIC, or high-end 32-bit processors like Power PC), or in microcontrollers (such as AVR, PIC, etc.), which typically include SPI controllers capable of operating in master-slave mode. Programmable AVR controllers in the system can be programmed using the SPI … Read more
1. What Sparks When C++ Meets Embedded Development? In our daily lives, electronic products come in various forms, from smartphones and smartwatches to electronic control systems in cars and automation equipment on industrial production lines. Embedded systems are truly ubiquitous. They act as the “hidden brain” of these devices, silently controlling everything, often with high … Read more
1. Interrupts: The “Emergency Contact” Between Devices and Processors In the complex operation of computer systems, interrupts are a crucial technology. Simply put, an interrupt is when the computer pauses the currently running program to execute a related service program upon encountering an urgent event that needs to be processed. Once completed, it automatically returns … Read more
