摘要
提出了利用PIC单片机作为控制核心的简易数字示波器的设计方案。介绍了系统总体设计的体系结构,以及硬件和软件的具体实现。输入信号经过预处理和AD转换后,传输到单片机,利用键盘做功能设置,在LCD上把波形显示出来,实现信号的实时采样、数据处理以及显示控制等简易数字示波器功能。此系统方案规模小、性能稳定、实现方便、价格低廉,具有一定的实用价值。
A design scheme for a simple digital oscilloscope using PIC microcontroller as the core is proposed. The architecture of the system overall design, and the implementation of the hardware and software are presented. The input signal is carried out pre-processing and AD conversion, and transmitted to the MCU, then displayed the waveform on the LCD by using the keyboard to do function setting, thereby achieving real-time signal sampling, data processing and display control functions of simple digital oscilloscope. The system features small scale, stable performance, convenient implementation, low price, has certain practical value.
