摘　　要：nRF52840是NORDIC公司近年推出的一个无线芯片,具有CORTEX-M4内核,支持多种接口和无线协议。该文基于该芯片设计了一个2.4GHz教学演示实验,几个从节点首先与一个主节点同步,然后在各自的时槽内向主节点发送数据包。文中给出了收发程序的详细设计,意在帮助学生尽快地熟悉这一芯片,尽快入门。nRF52840 is a wireless chip in recent years.With a CORTEX-M4 core,it supports many interfaces and several wireless protocols.In this paper,a 2.4GHz teaching demonstration experiment is designed with this chip.First,several slave nodes get syn⁃chronized with a master node,then send packets to the master in their own time slots.The detailed design of transmitting and re⁃ceiving program is presented to help students get familiar with this chip and get started as quickly as possible.
