摘要
本文介绍了以DM642和nNRF24L01为核心器件,对无线数字视频图像采集发射机的设计;介绍了DM642和nRF24L01芯片的性能。该设计将模拟摄像头采集的图像数据经过滤波、模数转换、放大等处理,调制到2.4GHz的载波上,由无线收发模块发射出去。选择通用的nRF24L01芯片,工作在2.4GHz频段,lMb/s的传输速率,采用其方便主控芯片编程的ShockBurstTM工作方式。
This paper introduces the design of wireless digital video image capture transmitter based on the core device of DM642 and nRF24L01;introduces the DM642 and nRF24L01 chip performance.The image data captured by analog cameras through the filter,analog-digital conversion,amplification and other processing,modulated to 2.4GHz carrier and launched out from the wireless transceiver.Select a common nRF24L01 chip,working in the 2.4GHz band,1Mb/s transfer rate,using the convenience of the master chip programming ShockBurstTM work.
