摘要
该设计在S3C2440处理器和uCOSⅡ下设计了基于CH375的U盘数据读写方案。该方案以数字频率特性测试仪为应用背景,给出了具体应用电路。软件设计基于嵌入式操作系统uCOSⅡ,保证了系统实时性和可扩展性,重点介绍了uCOSⅡ操作系统下的CH375读写方法。该方案在数字频率特性测试仪中运行良好,达到了预期的技术指标。
A design of USB data transmission based on CH375, S3C2240 and uCOS Ⅱ is introduced. The design was used in digital frequency sweeping instrument. The hardware implementation is included. The software design is based on embedded real time operation system uCOS H , which guaranteeing real time performance and scalability of the system. This paper also focuses on the method of the data transmission based on CH375 and uCOSⅡ. The anticipated design goal is reached when the USB data transmission was applied in digital frequency sweeping instrument,
