Last time I looked at the data area, this time I want to see what is running when jumping from the boot to here. /* * The reset code that is actually running. The code that runs from the beginning jumps here to run. */ reset: /* * Set the CPU to run in SVC32 mode. */ mrs r0,cpsr
The first step of autonomous driving is positioning. Knowing where you are can guide the route planning and control the car. Currently, cars mainly use GPS navigation. Since GPS is not very accurate, it can be within 2 meters in 95% of cases. When people drive the car, they only need to know the approximate location
According to market news on October 21, BYD intends to integrate its self-developed intelligent driving team under the New Technology Institute, with the goal of achieving mass production of self-developed algorithms as early as November this year, and continue to advance the self-developed process of intelligent dr
Function Call If a function is written after the main function, the function must be declared before the main function. Actual parameters: the parameters in the brackets when calling a function Formal parameters: The function is defined when the function is called, and the parameters in the bracke
The input subsystem consists of three parts: the driver layer, the input subsystem core, and the event processing layer. An input event, such as mouse movement, keyboard press, etc., reaches the user control application through the sequence of Driver- Inputcore- Event handler- userspace. System Block Diag
As can be seen from the figure, the P1_2 pin can sense the state of SW1. When SW1 is not pressed, P1_2=1 high level, and when SW1 is pressed, P1_2=0 grounded. Note: P1_2 pin only senses SW1 and does not affect SW1. #include "ioCC2530.h" //reference CC2530 header file /*********

We have written about Rivian's EE architecture before. As Rivian held an investor conference, it disclosed more information. Volkswagen Group plans to invest $1 billion in Rivian, a new American electric vehicle company, and plans to invest up to $4 billion more, with the total transaction size expected to reach $5
1. Principle Resolver is a position sensor commonly used in motor control. The function of the resolver is to accurately measure the position, speed and rotation direction of the motor rotor, transmit these signals to the electronic control, and control the motor by the software control algorithm. It
When programming with Omron CX-programmer software, we often use many comparison instructions. These instructions will generate some comparison flags, such as P_EQ for equal flag, P_GE for greater than or equal to flag, P_GT for greater than flag, P_LE for less than or equal to flag, and P_LT for less than flag.
Looking back at the 2023 series of articles, today we are talking about lidar. 01. Born at the wrong time: betting on an uncertain future Less than two months into 2024, both Hesai Technology and Sagitar Juchuang have experienced double losses in the capital market. On February 2, Hesai, which was listed on the
As self-driving technology expands from highways to urban roads, Chinese consumers' familiarity and preference for the technology are beginning to have an increasing impact on purchasing decisions. As the perception system is a key component for smart cars to realize autonomous driving, what kind of sensors to use and
Since most radio stations use a fully transparent transmission method, as long as the frequency band is the same, they can receive the voice signal sent on the same frequency band, so it is impossible to accurately identify whether the signal is useful. Radio stations with voice encryption function can avoid this si
According to news on August 2, according to patent data from LexisNexis, TSMC is ahead of other competitors in advanced chip packaging technology, followed by South Korea's Samsung Electronics and the United States' Intel. Advanced chip packaging technology is a key technology that can improve chip performance and is
At the 2023 World Artificial Intelligence Conference in Shanghai on July 6, Tesla founder and CEO Musk attended via video. At the meeting, he said that the number of robots in the world will exceed the number of humans in the future, and the system computing power of such robots will be much stronger. This will beco
For most electronic engineers, time domain signals are very intuitive and easy to understand, because the time domain is a real world and a domain that actually exists. All our experiences are developed and verified in the time domain, and everyone is accustomed to events occurring in chronological order and being rec

Rainy and humid weather is gradually increasing, and there are more and more reports for repairs due to leakage. I believe that all electrician friends are thinking a lot about finding the cause of leakage. In fact, Electrician Home tells you that you can easily find out the cause of leakage by using a multimeter in
In 1980, Bosch engineers began to study the problem of high-speed serial communication in automobiles, and released the CAN (Controller Area Network) bus in 1986. CAN is widely used in automobiles and various industrial environments due to its multi-master, high-speed (up to 1Mbps), and anti-interference characteristi
