基于PYNQ的传感器数据采集系统实验案例设计

Design of experimental case on sensor data acquisition system based on PYNQ

为了加强嵌入式系统设计实践教学的效果,提高学生解决复杂工程问题的能力,采用自顶向下的设计方法设计了传感器数据采集系统的实验案例。该案例采用ZYNQ-7000系列为核心的PYNQ-Z2硬件平台,通过Arduino接口连接传感器,利用Xilinx公司的Vivado及SDK进行软、硬件设计与开发。通过该实验案例,使学生深入理解ZYNQ-7000软硬件协同设计原理和方法,以及通过Arduino的模拟、数字、I2C、UART总线通信接口采集传送数据的方法,激发学生对"微处理器结构与嵌入式系统设计"课程的学习兴趣,提升实践教学效果。

In order to strengthen the effect of embedded system design practice teaching and improve students’ ability to solve complex engineering problems, an experimental case of the sensor data acquisition system is designed with a top-down design method. This case adopts the PYNQ-Z2 hardware platform with ZYNQ-7000 series as the core, connects sensors through Arduino interface, and uses Xilinx’s Vivado and SDK for software and hardware design and development. Through the experimental case, students can obtain an in-depth understanding of the principles and methods of the co-design of ZYNQ-7000 software and hardware, as well as the methods of data collection and transmission through the communication interface of Arduino’s analog, digital, I2 C and UART buses, which can stimulate students’ interest in learning microprocessor structure and embedded system design, and improve the effect of practical teaching.
