我想作usb2.0的移动硬盘适配器,请高手指教
我想做几个usb2.0大硬盘适配器。既可以接硬盘又可以接光驱的那种,
初步的设想是, 1。购买usb2.0的芯片(20片)(厂家未定,请高手指点) 2。适配器电路板设计,是否有普通的demo板呀(请高手指点) 3。适配器的firmware编程有没有框架的demo程序(请高手指点) 3。主机的驱动应该不用编成了吧。(请高手指点) 4。适配器的调试工具采用bus hound外,还需要什么工具。(请高手指点) 我很面,希望高手们不吝赐教,我做好了后,可以送几个给大家。 |

接IDC 和CD-ROM的 USB接口芯片(FT2232C) I have an assignment to make an IDE Conroller which must have to be controlled via USB.As the data on the IDE devices like Hard Disks and CD ROM's is 16-bit so I can use only FT2232C. I am aware of the fact that the data transfer speed would be slowed down to 12 MB/s instead of High Speed USB hard drives or CD ROMS which are available in the market have data transfer rates upto 480 MB/s but as FT2232c is easy to control and more over giving flexibility of using Bit Bang mode so I am preffering this chip to complete my project. 详情电话 谈 |
