February 22, 2022 January 22 Tuesday!

On such a rare special day, the editor can hardly contain his excitement. I wish you all the best of luck and good luck! In this season of saying goodbye to the old and welcoming the new, the editor will tell you a secret. Do you still remember the splendid stage and the extraordinary visual feast presented by high-tech in the 2022 Spring Festival Gala? The products of Hangshun vehicle-grade HK32MCU are indispensable! Dear friends who care about Hangshun chips, please listen to me one by one!

Technology empowers to create benchmarks

This year's Spring Festival Gala actively integrates XR, virtual, holographic and other cutting-edge technological means, so that new technologies, new ideas and stage effects are integrated, highlighting the spatial sense of panoramic stage beauty. The party chasing adopts a very subversive ground chasing system. The staff only needs to control the chasing gimbal on the ground to monitor the stage picture in real time and complete the corresponding chasing operation. The light tracking products produced by the standard HK32MCU have breakthrough improvements in many aspects such as light tracking effect, work efficiency, and equipment experience.

Regardless of the broadcast method, high-definition and colorful are the key requirements. In order to achieve better recording and broadcasting effects, this year's CCTV Spring Festival Gala used the light-following products produced by Hangshun vehicle-grade HK32MCU in the lighting. The rich and gorgeous macro effects provide more creative space for the artistic design of various performances, and the stable lighting effects provide a solid guarantee for the presentation of the TV and mobile screens, making the beautiful and ingenious stage effects. It may be truly and vividly conveyed to the audience, fully demonstrating the cultural flavor and sense of technology of the Spring Festival Gala stage. 

The Hangshun vehicle-grade HK32F103 series chip that shines on the 2022 Spring Festival Evening is a high-performance, high-reliability, mainstream, industrial-grade, and vehicle-grade 32-bit 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 SoC + high-end MCU supermarket dual strategy" HK32MCU series has now mass-produced more than 300 products from 29 families, and has become the first choice for domestic and foreign equipment suppliers and solution providers.
