Cy3663的主机固件程序-Cy3663 mainframe firmware

Mini Integrated Developement Environment was programmed for helping developers to get quickly familiar with the usage of USB2.DLL and the USB 2.6 module from Braintechnology using Visual Basic Version 6. Not all commands were shown, because many of them need to have custom hardware designs connected to be proofed , such as I2C, SPI and some parallel port modes that require handshake signals from hardware. The first step is to init a connected module by USBInit(), otherwise there is no firmware loaded and the module wonґ t work at all. Also by experimenting/programming it can be possible that the module must be resetted and initialized again. Keep in mind, that the module needs some seconds to be unplugged and also Windows needs some seconds to enumerate the module again, before it is ready again to be accessed by software. This is normal but sometimes confusing. -Mini Integrated Developement Environment was programmed for helping developers to get quickly familiar

所谓固件，就是存储在程序内存中的程序,用以完成驱动程序无法完成的USB 芯片及外围芯片的初始化及控制工作[23]。USB固件程序设计是USB接口部分的主要工作，它的主要目的是：当USB设备连接到主机上时，主机可以发现新设备，然后建立连接并完成数据传输任务，也就是能够让Windows正常检测和识别USB设备。因此在USB固件程序中，最重要的工作就是USB描述符的定义和USB传输中断的处理。-called firmware is stored in the memory of the procedure, Drivers used to complete the impossible chip and external USB chip initialization and control work [23]. USB firmware design is USB major part of the work, its main objectives are : When USB devices connected to the host, the host can be found in new equipment, then establish a connection and data transmission to complete tasks, is to let the normal Windows USB detection and identification equipment. Therefore USB firmware procedures, the most important work is described USB define and USB transmission interruption of treatment.
