Hello everyone! I have been in contact with CE intermittently. Today I encountered a problem. I used Samsung's original BSP and generated a new BSP with PB. Why is the content of the sources file in t...
In the electronics industry, DSP high-speed computing is suitable for image and audio compression and encoding and decoding, but not suitable for running interfaces. ARM fills this gap. Therefore, amo...
I believe that those who do embedded development know that non-volatile data storage is usually Flash, but there will usually be data loss. However, I have been thinking about what causes data loss. I...
We know that the general process of uboot starting the kernel is: start.s-->start_armboot-->main_loop-->rum_command-->do_bootm-->do_bootm_liunx But some of the specific details are still not clear. 1....
UHF and HF are both general technology categories, but each category has independent supporting protocols. HF is more consistent in the 13.56MHz frequency band, although there are many internation...[Details]
Pulse oximeters, non-invasive instruments used to monitor a patient's blood oxygen saturation, are benefiting from moving away from expensive discrete component solutions toward more integrated design...[Details]
Introduction: Design of automated test systems

In the development of high-stability lasers, real-time monitoring of the working state of the laser is an issue that needs to be focused on. This system realizes the high-stability laser temperatur...[Details]
Adding "intelligence" to measurement systems is becoming more common as 8-bit microcontrollers are inexpensive, widely available, and can be programmed using today's common high-level languages, su...[Details]
Lithium-ion batteries have a high energy-to-weight and energy-to-volume ratio, no memory effect, can be recharged many times, have a long service life, and are becoming increasingly cheaper. A good...[Details]
Abstract: This paper introduces the origin and new features of MP4, and introduces the core audio compression technology MPEG-2 AAC (Advanced Audio Coding) based on MP4. Finally, it briefly summari...[Details]
Abstract This paper
introduces a wireless radio frequency transmission chip nRF9E5 based on 8051 core. The remote control system of flapping-wing micro-aircraft is made by using this chip. Th...[Details]
At present, TPMS (tire pressure monitoring system) is mainly divided into two types, one is indirect type and the other is direct type. The direct TPMS system has been affected by its poor alarm ac...[Details]
Abstract:
Online dynamic signature authentication is increasingly used in various fields, especially in banking and financial systems and personal identification. As the basis of online signa...[Details]
Novaled, a German company, has successfully developed p-type and n-type field effect transistors based on a single-layer pentacene semiconductor layer by using its own p-type and n-type dopants. This ...[Details]
With the improvement of people's requirements for vehicle riding comfort and the development of passenger car suspension technology in my country, air suspension is increasingly used in passenger ...[Details]
With the continuous development of digital television, the demand for high-definition is imperative. H.264, as a new generation of compression standard, has a more complete algorithm than MPEG-2, ...[Details]
Development Status
Looking at the development of security monitoring technology: from the first generation of analog monitoring, to the second generation of digital monitoring, and then up...[Details]
"Where am I? Where am I going? Where is he/she? How far is he/she from me?..." Do you often have such questions like me? In fact, who can deny that these are questions that we often think about, ev...[Details]
