1. Memory Mapping In the memory mapping diagram of the STM32F429 chip, it can be seen that the peripherals are allocated 512M of space; however, the actual peripherals do not utilize the entire 512M of memory. When operating peripherals, it is sufficient to manipulate their corresponding memory addresses. For more detailed peripheral memory addresses, refer … Read more
Today, we will discuss interrupt handling in ARM Cortex-M. In embedded systems, interrupts are the core mechanism for achieving real-time responses. Imagine if there were no interrupts: • When a button is pressed, the system might be busy with other tasks and miss the response. • Incoming communication data might be lost due to untimely … Read more
From the small-scale power cycling and reset during controller debugging to the large-scale unforeseen shutdowns of power networks, every situation constantly tests the reliability of devices. High-end and complex control systems particularly highlight engineers’ attention to detail in their response mechanisms and protective measures against sudden power loss. NAND Flash/eMMC (NAND Flash with a Flash … Read more
In the company, some development environments (network environments, remote login environments, etc.) are set up by system engineers, and we just need to use them. However, when playing around on my own, I still have to tinker with it myself. Recently, I set up the network environment and remote login environment for my board, and … Read more

In recent years, incidents of supply chain disruptions have become frequent. Although the recent two incidents are not directly related to our country, they inevitably evoke a sense of loss and concern. First, ARM’s cancellation of the instruction set architecture license to Qualcomm indicates that commercial reputation is worthless in the face of economic interests. … Read more
Today, we are going to create something practical! I will teach you how to use Arduino to make a device that measures temperature and humidity. Not only can the data be uploaded to the cloud, but if it gets too humid or hot enough to fry an egg, it will also sound an alarm to … Read more
