1. STM32 and Selection 1.1 STM32 vs 51 Microcontroller Both STM32 and 51 are types of small computer chips that allow us to write code and store it within. For example, we can control a pin to switch between 5V and 0V, connecting an LED to this pin to achieve a blinking effect. This operation … Read more
1. Background Significance To address the after-sales maintenance issue of frequently disassembling product enclosures and upgrading on-site by professionals, the method ofIAP firmware upgrades is often adopted. Although this method solves the after-sales maintenance problem, it requires the embedded system to have interfaces such as serial ports, USB, and network ports, relying on computers, U … Read more

[Introduction] Since the release of the iBox related textbooks, many friends have expressed a desire for a detailed explanation of software development. Therefore, we will gradually share some details about IoT development with STM32 on the iBox. Today is the first chapter, where we will introduce how to port the standard official code (bare metal, … Read more
I have been developing microcontrollers for over ten years, and STM32 is the most worry-free microcontroller I have ever used. I have created at least over ten products using STM32. In fact, it’s not just STM32; the STM8 series is also very stable. The first ARM core microcontroller I encountered was from NXP. After using … Read more
