On the evening of February 20, the closing ceremony of the 24th Winter Olympic Games was held at the Beijing National Stadium, bringing the 17-day wonderful Winter Olympics to a close.

​The opening and closing ceremonies of the Winter Olympics made extensive use of new technologies such as artificial intelligence, machine vision, 5G and cloud technology to integrate theatrical performances with the ceremonies, creating a “different” opening ceremony for the Beijing Winter Olympics. In the opening and closing ceremonies, we are particularly proud of the fact that 100% of the lighting equipment used in the venue is made in China. At the Beijing Winter Olympics site, which is 100% impossible to go wrong, it is produced by Hangshun vehicle-grade HK32MCU. The stage lighting and other equipment have achieved the stability of equipment operation, maintenance, light quality, lighting effect, etc., which can not only create a warm atmosphere in the arena, but also cooperate with other performing arts equipment to jointly dedicate a romantic, beautiful and beautiful to the world. A warm snow festival.

The opening ceremony was simple and exciting, but the "simple and romantic" was still carried out to the end at the closing ceremony. In the colorful and exquisite opening and closing ceremonies, Hangshun Chip, as a leading ARM® Cortex 32-bit MCU design and production enterprise in China, adhered to the concept of "Hangshun Chip, China Chip, World Chip" and cooperated with partners for the Winter Olympics. will empower. 

In line with the opening ceremony, the closing ceremony still highlights the technological content. Through the power of science and technology, the "ethereal and romantic" feeling of the closing ceremony runs through the audience. On the stage of "few people but not empty", stage lighting is an important element to present exquisite and high-quality performance effects. Hangshun vehicle-grade HK32MCU performs well in low temperature, long-term and high-intensity use environments, and has withstood severe tests. It guarantees smooth processing with zero failure rate from beginning to end, and ensures stable and reliable operation of the system.

Hangshun car-grade HK32MCU stage lighting equipment, which performed well at the opening and closing ceremonies, has high color rendering light source and extremely high saturation color reproduction, providing clear and seamless color transitions, presenting a real and natural high-definition texture, which meets the needs of the stage. Light needs, and at the same time endows the stage with agility and charm, presenting romantic beauty to the eyes.

The Hangshun vehicle-grade HK32F103 series chip that shines brightly at this Winter Olympics is a high-performance, high-reliability, mainstream, industrial-grade, and vehicle-grade MCU. Since mass production, it has been widely used in stage lighting, automotive electronics, industrial control, medical electronics, image processing, speech recognition, motor control, security monitoring, IoT low-power sensor terminals, household appliances, intelligent robots and other fields. The "Hangshun vehicle-specific SoC + high-end MCU supermarket dual strategy" has now mass-produced more than 300 HK32MCUs, which has become the first choice for domestic and foreign equipment suppliers and solution providers.
