During the firmware upgrade process of the STM32 microcontroller, many engineers choose the IAP technology, which allows firmware updates to the microcontroller via the host computer while the application is running. However, occasionally, there may be a low probability of encountering a runaway phenomenon. How to solve it? 1. Check Power Supply Voltage Ensure that … Read more
A ASIC (Application-Specific Integrated Circuit) – A piece of custom-designed hardware in a chip. address bus – A set of electrical lines connected to the processor and all of the peripherals with which it communicates. The address bus is used by the processor to select a specific memory location or register within a particular peripheral. … Read more
Understanding OBG in Microcontrollers: The STM32 microcontroller’s core (Cortex-M3) contains a hardware debugging module that supports various complex debugging operations. The hardware debugging module allows the core to halt when fetching addresses or accessing data—this is the assurance we have for online simulation during microcontroller development and debugging.When the core is halted, both its internal … Read more
1. Introduction to Cortex-M0 Processor Core Exception Interrupts The Cortex-M0 core is equipped with an exception response system that supports numerous system exceptions and external interrupts. Among them, numbers 1-15 correspond to system exceptions, while numbers greater than or equal to 16 are all external interrupts. The smaller the numerical value of the priority, the … Read more

RealView MDK integrates the most advanced technologies in the industry, combining the features and functions … Read more
1. Introduction to H-JTAG: H-JTAG is a simple and easy-to-use debugging proxy software, similar in functionality to the popular MULTI-ICE. H-JTAG includes three software tools: H-JTAG SERVER, H-FLASHER, and H-CONVERTER. Among them, H-JTAG SERVER implements the debugging proxy function, H-FLASHER implements the FLASH programming function, and H-CONVERTER is a simple file format conversion tool that … Read more
Abstract: The cross-development environment is the foundation of embedded Linux development. The subsequent development process is almost entirely based on this environment. ARM, as a high-performance, low-cost embedded RISC microprocessor, has become the most widely used embedded processor. This article includes the hardware structure of the 32-bit ARM920T core “GEC2410” development board and the concept … Read more
Vivado (Vitis) Version: 2020.2 FPGA Development Board: Microphase Z7-Lite 7020 Development Board FPGA Design Debugging Process FPGA development is an iterative process, and the general FPGA design process typically includes the following steps: Hardware architecture and algorithm verification: what modules are needed to implement the required functionality, how modules communicate and connect with each other; … Read more
This is definitely a good article. Printing with this function is sometimes more useful than any debugging tool, and the kernel’s prink is a true gem. But how does the printf function connect with the UART driver? This article will answer that for you. Like, share, and bookmark it for when you need it. Today, … Read more
I2C Protocol Application: Sensor Interface and Data Reading I2C Protocol Application: Sensor Interface and Data Reading Hello everyone, I am Daodao. Today, let’s talk about the I2C protocol, which many sensors use to communicate with microcontrollers. Although it only uses two wires, it can connect multiple devices, making it a master of saving wires. However, … Read more
