在旋转LED显示系统中, 为了使显示的信息画面能实时、快速地更新, 文章以STM32为主控CPU, 利用霍尔传感器和编码器, 实现 LED显示信息的准确定位; 通过旋转LED软件控制平台, 录入要更新的画面信息, 应用无线射频技术, 准确可靠地将更新的显示信息传输到旋转LED显示系统中。设计方法经实际制作测试, 取得了良好的效果。

In the rotating LED display system, in order to display the information of picture in real-time and update fast, the paper takes the STM32 as the main control CPU, using the Holzer sensor and encoder, the accurate position of LED display information is realized. The picture information can be input and updated through rotating LED software control platform. The displayed information can also be updated and transmitted to the rotating LED display system accurately and reliably. Through the actual production test,the design achieved good results.
