Recently, someone asked: What is the relationship between ARM9 and STM32? If we rewind 10 years, ARM9 and S3C2410 were quite popular, but the “new era” ARM processors like STM32 have also emerged. ARM9 is an early ARM processor, while STM32 is a more modern processor that has gained popularity in recent years. ARM Naming … Read more
Getting Started: Bare-Metal Programming on ARM Cortex-M Microcontrollers Bare-metal programming typically refers to the process of writing programs to control hardware devices directly without an operating system. For embedded system developers, this is a fundamental and important skill. Today, I will guide you through how to implement bare-metal programming on ARM Cortex-M series microcontrollers. Starting … Read more
Hello everyone, I am Pi Zi Heng, a serious technical enthusiast. Today, I will introduce the ARM Cortex-M stack mechanism. This article is a technical document I wrote before 2016, and I have spent some time reorganizing the format. Previously, I discussed the “Principle of Stack in Embedded Systems”; this article serves as an engineering … Read more
Hello everyone, I am Pi Zi Heng, a serious tech enthusiast. Today, I will introduce to you the high-frequency products of domestic Cortex-M core MCU manufacturers. Yesterday, I released the “2023 Edition of Domestic Cortex-M Core MCU Manufacturers High-Frequency Products,” where I found 12 models with a frequency of no less than 144MHz, which has … Read more
Hello everyone, I am Pi Zi Heng, a serious techie. Today, I will share with you the principles of the Cortex-M interrupt vector table and its redirection methods. Continuing from the previous article “Three Implementations of Critical Section Protection in Embedded Cortex-M Bare Metal Environment”, in embedded code design, sometimes certain special operations (such as … Read more
