摘　　要：介绍一种基于AVR单片机和USB通信协议的便携式多道核谱分析仪的设计。阐述了高性能A/D转换器、USB接口芯片与单片机的硬件接口设计,以及AVR单片机和上位机的软件设计。A kind of portable mutil-channel nuclear spectrum analyzer based on AVR MCU and USB protocol is introduced. On the hand of hardware, we give the interface of MCU to A/D converter AD976A, also to USB controller FT245BM in detail. While face the software, we show our blueprint of the firmware in MCU, and the real-time displaying application on PC, which is compiled by C^＋＋ Builder 6.
