Work Mode Thread mode: This mode is active when the processor is reset or exits from an exception. Code in this mode can be either privileged or user code, controlled by CONTROL[0]. Handler mode: This mode is entered when an exception (including interrupts) occurs, with all code having privileged access. Code Privileges Privileged access: Full … Read more
Bit-banding operations may not be used as much now, but in the past, when MCU performance was not very good, bit-banding operations were a common operation among many software engineers. This article mainly discusses the Cortex-M3 core (STM32F1), and I believe many friends have been confused when they first learned about it. 1About Bit-Banding Operations … Read more
Which is more powerful, Arduino or STM32? Many electronics enthusiasts face a dilemma when choosing between Arduino and STM32, unsure of which to use. Arduino has always been popular, but STM32 has more interfaces, stronger performance, and faster speeds? Features of Arduino and STM32 Arduino: Arduino leans towards creativity, simplifying hardware operations. Its functions and … Read more
First, let me clarify that MPU has many meanings, and there are two common ones: MPU:Memory Protection Unit; MPU:Microprocessor Unit; Additionally, some may associate it with modules like MPU-6050. So, please do not confuse MPU. Why Use MPU? If you develop embedded projects that suffer significant economic losses or major accidents due to memory overflow … Read more
In business, “must” represents the minimum requirements for market participation. Today, there are over a hundred open-source and commercial RTOS in the embedded market, most of which lack functional safety certification. Given this, it is clear that RTOS functional safety certification is not yet a “must” today, but perhaps it should be. RTOS is the … Read more
