CYPRESS CY7C69013A使用的驱动！-CYPRESS CY7C69013A driver to use!

This example firmware is based on Microchip s USB Support Firmware. The purpose of this example is to provide a model for making a USB combination device. This mainly entails having the USB descriptors set up correctly. File usb_ch9.c contains the mouse and keyboard descriptors in the correct configuration. The main routine of this example moves the cursor in a circle and sends keyboard keycodes for the message "Microchip USB" over and over again. Some advice: Before running this firmware open a blank text document. Make sure that when you run the device/emulator that you are able to give focus to the document. The cursor will be moving in a circle so make sure you have plenty of room to click on the editor window. This will allow you to see the message "Microchip USB" without inadvertently having the message type over an existing document.-This example firmware is based on Microchip s USB Support Firmware.

usb device test Speed

High volume USB 2.0 devices will be designed using ASIC technology with embedded USB 2.0 support. For full-speed USB devices the operating frequency was low enough to allow data recovery to be handled in a vendors VHDL code, with the ASIC vendor providing only a simple level translator to meet the USB signaling requirements. Today s gate arrays operate comfortably between 30 and 60 MHz. With USB 2.0 signaling running at hundreds of MHz, the existing design methodology must change.
