I am going to learn the driver of DSP video port (VP port). I first read the operating system and driver development manual to understand the working principle and program structure of the driver, and...
Suddenly I felt like I had fallen into a bottomless pit. I originally wanted to learn application programs, but my boss said that the driver department was short of people and wanted me to learn drive...
We know that most of the workers who can access CAD drawings are designers or engineers; their work is very rigorous and scientific, and they cannot afford any mistakes. When they convert the designed...
Since we need to consider the active antenna and its LNA, it is not enough to measure the RF link only at the RF front end. We must measure it through the antenna and spatial coupling to get closer to...
Recently, I downloaded CCS out of curiosity and found that CSS is really inconvenient for novices. The project that was tested and run on IAR failed to compile successfully due to insufficient memory ...
The rapid development of the Internet has realized high-speed information transmission and resource sharing, greatly facilitating people's lives. Embedded systems are widely used in various electr...[Details]
introduction
In the discharge process of tokamak plasma physics, the study of rupture and sawtooth is of great significance. Rupture and sawtooth exist in most tokamaks. Rupture is a notew...[Details]
No matter which processor you are learning, the first thing you need to understand is the registers and working mode of the processor.
ARM has 37 registers, including 31 general registers and ...[Details]

The TPS92210 is a single-stage LED lighting pulse width modulation (PWM) controller. The TRIAC dimmable solution not only regulates the LED current, but also achieves a power factor close to 1. The...[Details]
1 Basic Features
In computer control systems and various intelligent instruments and meters composed of single-chip microcomputers (or microprocessors), various external analog signals must be ...[Details]
Car lights, whether headlights, fog lights or tail lights, play an important role in driving safety. However, the material of the car lights determines that the probability of damage in a collision...[Details]
summary
This article will briefly analyze the success and shortcomings of high-frequency DC-DC switching power supplies in the process of miniaturization (the second basic goal), and propose m...[Details]
1 Introduction to the overall system solution
The hardware part is mainly used to amplify the sound. When the sound is loud enough, the signal can be introduced into the microcontroller for de...[Details]
The principles to be followed are as follows:
(1) In terms of component layout, related components should be placed as close as possible. For example, clock generators, crystal oscillat...[Details]
Designing low power circuits while achieving acceptable performance is a difficult task. Doing so in
the RF
bands increases the challenge dramatically. Today, nearly everything has wireless...[Details]
Abstract: Based on the analysis of the characteristics of the IRIG-B (DC) code type, a design method for IRIG-B (DC) time code decoding is proposed. This method consists of a small number of periph...[Details]
