多功能微控制器与可编程逻辑器件实验箱设计

Design of multifunctional microcontroller and programmable logic device experimental box

为了提高实验设备的利用率,提出一种多功能微控制与可编程逻辑器件实验箱设计方案。该实验箱采用"主板+核心板"的模式,主板上集成输入模块、输出模块、模拟量模块、串行总线模块、通信模块和电源模块,核心板有4款,包括51单片机、STM32单片机、CPLD及FPGA。实验证明,核心板能够控制主板上的所有模块,完成单片机与可编程逻辑器件的仿真及下载实验,具有性价比高、操作简单、扩展性强、升级方便等特点,可在单片机、数字电路与数字逻辑、EDA技术、嵌入式系统、物联网技术等课程中推广使用。

In order to improve the utilization ratio of experimental equipment, a design scheme of multi-functional micro-control and programmable logic device experimental box is proposed. The experimental box adopts the mode of "Motherboard + core board". The motherboard integrates input module, output module, analog module, serial bus module, communication module and power module, and the core board has four modules including 51 MCU, STM32 MCU, CPLD and FPGA. The experiment proves that the core board can control all the modules on the motherboard and complete the simulation and download experiments of the MCU and programmable logic device, which has the characteristics of high cost performance ratio, simple operation, strong expansibility and easy upgrading. It can be widely used for the courses of the MCU, digital circuit and digital logic, EDA technology, embedded system, Internet of things, etc.
