[font=微软雅黑][b]3.1 GPIO driver and development3.11 Principle analysis:[/b] We have learned 51 MCU and used IO port before. Compared with 51 IO, Cortex M4 IO configuration is a little different. 51 does...
When I write this sentence in the program: Push_Key = (P1IFG&(~P1DIR)); to read which button is pressed, there will be a reminder undefined behavior: the order of volatile accesses is undefined in thi...
Diodes are also called crystal diodes, or diodes for short. In addition, there are early vacuum electronic diodes; they are electronic devices that conduct current in one direction. Among electronic c...
I finished the first experiment of the marquee, and I did the second experiment again. I found that after I powered on the DSP board, the experiment that was downloaded to it for the first time was st...
"Precision" is used to describe the accuracy of physical quantities, which reflects the error between the measured value and the true value, while "resolution" is used to describe the scale division, ...
In the MSP430 microcontroller, one clock cycle = the inverse of the MCLK crystal oscillator. If the MCLK is 8MHz, then one clock cycle is 1/8us.
One machine cycle = one clock cycle, that is, each acti...
On August 24th, Tesla CEO Elon
Musk
revealed information about the upcoming FSD V14, claiming it will outperform human drivers. Tesla FSD lead Ashok stated last year that FSD version 12.5, ...[Details]
To understand why car engines need gearboxes, we must first understand the characteristics of different types of engines. An engine refers to a machine that can convert a form of energy into kineti...[Details]
In mobile technology, sensors are the primary input for measured signals and form a component of a sensor system. They include sensitive and transducer elements connected to carriers and circuits. ...[Details]
As time goes by, people are increasingly concerned about their own and their families' health. However, existing monitoring devices for individual vital signs have struggled to gain market share du...[Details]

On August 22, according to CNBC's report today, the National Highway Traffic Safety Administration (NHTSA) is launching an investigation into Tesla, and the latter is questioned whether it has fail...[Details]
Linear motor modules have become the "sweet spot" in various fields due to their advantages such as long stroke, fast speed, high precision, smooth operation and long life. Different models of line...[Details]
Inverter power supplies on the market can generally be divided into two categories: sine wave inverters and square wave inverters. Some engineers also like to categorize pure sine wave inverters as...[Details]
A pure sine wave inverter has a good output waveform with very low distortion, and its output waveform is essentially the same as the AC waveform of the mains power grid. In fact, the AC power prov...[Details]
Tires are a very important component for cars. They are related to the driving experience of the vehicle. We are almost inseparable from cars in our daily lives. For tires, according to the role of...[Details]
I recently read an article in the Wall Street Journal titled "We need the right to repair our gadgets" (reference original article: ). The author was very angry about the phenomenon of "planned obs...[Details]
The mobile computing market is rapidly evolving, and manufacturers are fiercely competing for market share. A key area of competition is battery life, which encompasses two key aspects: how long th...[Details]
The characteristics of electric vehicles place high demands on the motors they use. To increase top speed, the motor should have high instantaneous power and power density (W/kg); to increase drivi...[Details]
Electronics engineers all know that transient voltage suppression (TVS) diodes are used to protect ports, preventing damage to downstream circuits caused by transient voltage surges. In short, TVS ...[Details]
