In embedded project development, STM32CubeMX is widely used for its visual configuration and one-click generation of initialization code. However, as project complexity increases, we gradually find that the structure of the code generated by CubeMX, while convenient for beginners, is not conducive to code reuse and cross-project migration. To address this issue, extracting and encapsulating … Read more

Learning how to configure IO allows you to output the desired voltage levels and read the voltage levels from the IO ports.This article introduces the GPIO of … Read more
OV7670, an image sensor, is compact, operates at low voltage, and provides all functions of a single-chip VGA camera and image processor. Introduction to the Chip Introduction to STM32F407 The processor used in this system is the STM32F407 from STMicroelectronics, which features a 32-bit Cortex-M4 core with floating-point operation capabilities, making it a low-end high-speed … Read more
ISP uses communication interfaces for programming, and the boot code is written by the manufacturer and cannot be changed. IAP (In-Application Programming) refers to the ability of an MCU to obtain new code and reprogram itself, allowing a program to change the program. In application programming (IAP), the user’s application code erases/programs the internal Flash … Read more

The Cortex-M0 is part of the M0 series within the Cortex-M family. Its main feature is a low-power design. The Cortex-M0 is a 32-bit, 3-stage pipeline RISC processor, with a core architecture based on the von Neumann structure, meaning that instructions and data share the same bus. As a next-generation processor, the design of the … Read more
In embedded system design, selecting an ADC chip requires a comprehensive consideration of performance, application scenarios, and development costs. The STM32’s ADC and dedicated ADC chips like the AD7606 exhibit significant differences in core parameters, functional features, and applicable scenarios. Below is a comparative analysis and selection advice for both: 1. Performance Parameter Comparison 2. … Read more
