Lane Departure Warning Illustration Lane Departure Warning System is a system that assists drivers in reducing traffic accidents caused by lane departures through alarms. The basic components of the lane departure warning system include image processing chips, controllers, and sensors. This system provides intelligent lane departure warnings, capable of issuing alarms 0.5 seconds before the … Read more
First, a statement: This tutorial is not aimed at beginners, so it absolutely will not cover the installation of Quartus II or USB Blaster; if you really want to solidify this part, you can refer to the PDF in the ‘User Manual’. 1. USB Driver and Connection Instructions Everything is ready except for the east … Read more
Many people do not know how to write programs by looking at timing diagrams. Below, we will analyze a non-standard I2C device and teach everyone how to write an efficient IO simulation of I2C timing. Observing the timing diagram, it includes the I2C start signal, I2C stop signal, I2C acknowledgment, non-acknowledgment, response acknowledgment, as well … Read more
“How convenient would it be if this car could automatically brake!” “I crashed into the wall again while reversing!” “My foot is about to break from driving on the highway,” we often heard many such complaints and frustrations years ago.

The typical ASIC design process can be divided into logical design and physical design. Logical design starts with high-level design specifications and chip architecture. The chip architecture describes high-level functionality, power consumption, and timing (the speed at which the design operates) requirements. This is followed by a description of the design at the register transfer … Read more
There is no doubt that as “autonomous driving” continues to dominate headlines, the so-called “ADAS” (Advanced Driver Assistance Systems) has quietly sparked a wave of transformation, fundamentally changing the way traditional cars are controlled and the user experience. The current mainstream ADAS systems can achieve functions roughly divided into blind spot monitoring, lane departure warning, … Read more
Introduction: Autonomous driving has always been an intriguing concept. At this stage, how to make ADAS more accessible is crucial for the development of intelligent driving. Autonomous driving has always been an interesting concept. On one hand, it is very hot. Not only Google and Baidu, but many automakers are working on it, as if … Read more
