With WIFI, it can directly connect to the home WIFI router and access the internet. At this point, it acts like a small computer or smartphone, making it very convenient to connect to the … Read more
Must-Read Books for Beginners in Embedded Arm Linux Recently, a student who just started learning Arm Linux asked me for advice on good books for beginners. Embedded Linux is a vast system that involves hardware and computer science, bridging electronics and computing. Many students from electronics-related majors are unfamiliar with computer principles and operating systems, … Read more
Most applications using Cortex-M3/M4 MCUs are portable and powered by batteries or energy harvesting systems. Therefore, most of the concepts discussed in this article involve how to reduce overall system energy consumption. However, in many cases, these energy-saving technologies are also powerful tools for processor application design, providing more cost-effective solutions, greater design redundancy for … Read more

Some research firms have fully considered the effects of the pandemic in their forecasts. Considering the state of embedded systems using microcontrollers (MCUs), they believe the MCU market … Read more
When you want to save the hard drive on your PC, the backup program writes a complete image of the memory contents to a storage medium (such as another hard drive). However, the RevPiCore does not have a hard drive as storage medium. It uses an embedded multimedia card (eMMC) instead of a hard disk … Read more
Submitted by Archer. Hello everyone, long time no see, I am Archer. Recently, I got some low-cost boards and also bought a Raspberry Pi 1 on Xianyu, which I have been keeping idle. I thought about flashing OpenWrt to use it as a high-performance soft router, but unfortunately, the performance is not enough. Under OpenWrt, … Read more

This project uses a Raspberry Pi with ultra-low-cost software-defined radio (SDR) hardware to receive tracking information sent by airborne S-mode transponders from millions of miles away. The Raspberry Pi is equipped with a sleek 3.5-inch TFT display to provide a convenient overview of aircraft activity. Hardware The RTL2832U-based tiny SDR receiver (124-5461) was originally designed … Read more
