The proposal based on USB Host/Slave controller chip CH375A, realized a USB-Host embedded in CAN bus data acquisition system and stored acquisition data of each node in U flash disk under MCU control.
该方案基于USB主/从控制芯片CH375A，在单片机的控制下，实现了CAN总线数据采集系统中嵌入USB主机，从而完成把各节点采集的数据存入U盘，取代了现场数据采集系统必须有一台计算机的模式。
The interface can be used in embedded system which need fast switch between USB host mode and slave mode. And it can be communicated with U disk in host mode and PC in slave mode.
最终实现了嵌入式系统USB主从模式的快速切换以及在主机模式下与U盘、从机模式下与PC机的通信。
