摘要
设计了一种基于FreeRTOS嵌入式操作系统的二维条码无线传输系统,描述了系统的软硬件实现方法和多点数据传输的链路控制机制。系统主控芯片采用通用的MCU芯片STM32,结合二维码扫描引擎和蓝牙传输模组实现多个扫描终端与基座间的数据传输。
An embedded wireless transmitting system for two-dimensional bar code data is designed in this paper based on FreeRTOS. The design method of the software and hardware, together with the mechanism of the point-to-multipoint link control is introduced in detail. The STM32 as the main control MCU, the scan engine and the Bluetooth transmission module are used to achieve the data transmitting between multiple scanners and single cradle.
