USB 2.0 Interface

The USB-LAN EZ-Extender allows you to connect a USB 2.0 chip to a Blackfin processor without any other programmable logic required. PLX’s (formerly Netchip) Net2272 device ties directly to the asynchronous memory bank 3 of the Blackfin processor. You can read from and write to the USB 2.0 controller by directly addressing the named memory bank.

You can reset the Net2272 processor by asserting LOW these flag pins: PF11 on the ADSP-BF533 processor, PF6 on the ADSP-BF537 processor, and PF11 on the ADSP-BF561 processor.

The flag pins can be used for push buttons or LEDs on the respective EZ-KIT Lite; consequently, the user must make the proper changes to that EZ-KIT Lite. The switch settings required for each of the respective EZ-KIT Lites are described in the USB Software Readme.txt file in the

...\Blackfin\Examples\USB-LAN EZ-EXTENDER\USB subdirectory of the

VisualDSP++ installation directory. The readme file describes the USB software, source code, drivers, and explains how to run a USB-based application.

For correct switch settings, refer to the schematics drawing of the respective device.
