基于FreeRTOS和STM32的手持激光测距仪系统设计

Design of the Hand-Held Laser Range Finder System Based on FreeRTOS and STM32

以ARM Cortex-M3处理器STM32F103RBT6为核心,结合激光调制和解调电路,设计手持式激光测距仪。在此硬件基础上,嵌入式软件系统采用FreeRTOS实时操作系统,充分利用FreeRTOS的多任务调度、任务通信、任务同步和软时钟等功能。以模块化思想编写系统软件,降低各功能模块之间的耦合性,使软件系统流程变得简洁流畅。经过实际验证,系统运行稳定、响应速度快、稳定性高,手持式激光测距仪的使用体验也得到提高。

Based on STM32F103RBT6 which using ARM Cortex-M3 as the architecture, combined with laser modulation and demodulation circuit, designs the hand-held laser range finder. Based on the hardware flat, the embedded software system adopts FreeRTOS real-time operating system, makes full use of FreeRTOS task scheduling, task communication, task synchronization, soft clocks and other functions. Designs the program from the perspective of modular design, reduces the coupling between the various functional modules, makes the software system process become concise and fluent. Through the actual verification, the system has the advantage of running stably, fast response and high stability, also improves the user experience of hand-held laser range finder.
