If you are into IoT or Embedded Systems, you must have come across the HC-SR04, commonly known as the ultrasonic distance sensor, which is used to measure the distance of objects. This sensor is included in most Arduino kits, and it was also the firs...
In the fields of the Internet of Things and embedded development, Bluetooth chips are crucial components for wireless communication. The KT6368A is a low - cost pure - data chip that supports Bluetooth 5.1 dual - mode (BLE + SPP) and is widely used i...
📘 Introduction This is Part 2 of our 5-part series on concurrency and timing mistakes in Embedded C. In Part 1, we discussed the dangers of using delay() or busy loops for timing. In this part, we’ll dive into a more subtle and dangerous issue: race...
I. Problem Description The testing agency Luxshare reported that the sample sent by the customer failed the wireless KC (Korea) test, mainly in the following two aspects: The receive spurious of the Bluetooth part does not meet the standard. The Bl...
Working on embedded systems or SBCs (Single Board Computers) is challenging enough, but getting your work seen can be just as hard. Engineers today don’t just need working hardware and software—they also need visibility. The good news is that there a...
In the field of smart home, there has always been room for improvement in the sound experience of doorbells and home appliances. The monotonous "ding - dong" sound when the courier rings the doorbell and the uniform prompt sound when family members t...
In the world of embedded systems, two key elements drive innovation: displays and single board computers (SBCs). Whether you are developing an industrial HMI, a medical imaging device, or a next-generation smart home control panel, choosing the right...
In today’s fast-moving edge computing world, industrial systems are no longer just about controlling machines. They now need real-time video analytics, AI inferencing, and smooth GPU-powered interfaces—right on-site, without depending fully on the cl...
Since the advent of Bluetooth headphones in 1999, the sound quality of Bluetooth audio devices has been a topic of great concern. In the early days, due to the limited bandwidth of Bluetooth, the label "just for basic sound" was attached to them. In ...
📘 Introduction In embedded systems, timing isn’t just important - it’s everything. From handling sensor data to controlling actuators or maintaining communication protocols, precise timing and safe concurrent execution are critical to ensuring syste...
