单片机创新实验板系统的设计与应用

摘要

传统教学用实验箱缺少培养学生独立设计硬件的环节，偏重软件设计，学生动手能力和创新性不足。为此，引入了模块化思想，将系统按功能分成6个模块，设计了创新实验板系统，采用串口通信原理，实现宿主计算机和单片机之间的通信问题。该系统要求学生根据需求，自主选材、独立设计并焊接实验板，编程之前需要自己设计实验方案并进行连线。该系统使学生参与从硬件设计到软件实现的单片机应用系统开发的全部过程，有效地弥补传统实验箱在硬件教学上的不足，全程培养学生动手能力和解决问题的能力。结果表明，本系统具有很好的稳定性和灵活性。%The tradition experiment equipment in MCU focuses on software design and lacks of cultivation hardware design for students; therefore, the innovation and practical ability of students is weak. However, we employ module methodology and divide the system into six modules which is adopted serial ports for communications of host and MCU. The proposed system supports that the student can individually select corresponding chips and modules for his application after his connections of corresponding modules, which offers the whole MCU development process from hardware design to software implementation for students. The proposed system fills the lack of the tradition experiment equipment in MCU. The result indicates that the proposed system contains stability and flexibility in practical use.
