摘要
本系统在DSP采集处理信号的基础上加入USB主机接口,数字信号处理芯片TMS320VC5402完成信号采集,USB控制芯片SL811HS完成数字信号的存储,直接实现两种设备间的数据传输和存储。
Collecting and storing data are two links of industrial control system. This paper studies how to add USB interface on DSP in order to achieve data transmission and storage directly between two sorts of equipments. In this system,the DSP chip (TMS320VC5402) collects signals while the USB interface chip (SLSllHS) stores digital signals.
