ISP1362是Philips公司的一款USB接口芯片,内部有3个USB控制器——主机控制器、设备控制器和OTG控制器,可以设置为USB主机模式、设备模式以及OTG模式,因此具有较强的灵活性,尤其是OTG的工作模式,使得许多设备可以脱离PC机进行数据传输和通信。介绍ISP1362的常用功能,即该芯片作为主机控制器时的使用,并以USB鼠标为例,介绍了他在SOPC中作为USB主机模式的应用,并能试验板的液晶屏上看到其移动的方向,完成了嵌入式系统的外设功能。
ISP1362 is a USB interface chip of Philips Company, there are 3 USB controllers in the host - host controller, device controller and OTG controller, can be set to USB host mode, device mode and OTG mode, so it has stronger Flexibility, and especially OTG’s mode of operation, allows many devices to move data and communicate off the PC. This paper introduces the commonly used functions of ISP1362, that is, the use of the chip as a host controller and an example of a USB mouse as an application of USB host mode in SOPC, and can see the movement of the ISP Direction, completed the embedded system peripheral functions.
