1. The AHB system bus is divided into APB1 (36MHz) and APB2 (72MHz), where 2>1 means APB2 connects to high-speed devices. 2. Stm32f10x.h is equivalent to reg52.h (which contains basic bit operation definitions), while stm32f10x_conf.h is specifically for controlling the configuration of peripheral devices, essentially acting as a switch for header files. 3. HSE Osc … Read more
Recently, someone asked a question: how to find authoritative information about STM32? Actually, I have always recommended that everyone obtain information from the chip manufacturer (official sources), as this information is generally the most authoritative. This article mainly introduces methods and tips for quickly finding STM8 and STM32 software tools and documentation. ST Website ST … Read more
1. Introduction to GPIO GPIO stands for General-Purpose Input/Output, which can be simply understood as the pins controllable by STM32. The GPIO pins of the STM32 chip connect to external devices, enabling communication, control, and data acquisition with the outside world. The GPIO pins of the STM32 chip are divided into several groups, each with … Read more
The STM32 MCU from STMicroelectronics has evolved over more than a decade, resulting in numerous series and specifications, making it overwhelming for many users to choose from. How complex are the STM32 models now? The official selection manual from 2019 has as many as 75 pages. Students who need the 2019 STM32 selection manual can … Read more
1. Single Channel Sampling Reference Materials: “Practical Guide to STM32 Library Development” by Liu Huoliang and Yang Sen We will skip the theoretical aspects as they are well explained in the book above, let’s directly look at the hardware circuit diagram. Here, we are using a 3362 potentiometer (10K), measuring the voltage across PB0 and … Read more
来源：STMCU Issue: The issue was raised by a customer and occurred on the STM32F103VDT6 device. According to their engineer, in the product design, the STM32’s HSE external 8MHz crystal generates oscillation, and then through the STM32’s internal PLL, it is multiplied to 72MHz, serving as the system clock to drive the chip. There is a … Read more
