USB Interface
03/01/10 at 12:04pm
 
Hi, I am new to the SRV-1 scene. I am trying to hook up a USB interface to the SRV-1 micro computer. Has anyone done this or can anyone tell me how or direct me in the right direction? That would be great thanks!

What USB interface are you using ?  Is the serial portion of the interface 3.3V ?  If not, you could damage the Blackfin board.

I had some experience, and connected Blackfin board
to USB-FIFO module DLP-USB1232H ( http://www.dlpdesign.com/usb/usb1232h.shtml ).
http://81.17.152.8/download/test/Rover20/CIMG2105.JPG
BlackFin board => FIFO->USB => Usual PC (x86).
Speed ~2MBytes/sec. I used H8-H15 as databus and  
#define      FTDI_TXE      1      // IN
#define      FTDI_RXF      2      // IN
#define      FTDI_WR            4      // OUT
#define      FTDI_RD            5      // OUT
#define      FTDI_SND      7      // OUT
 
160x120 transferred with 50fps
320x240 transferred with 14fps
It was really outstanding (and timeconsuming) task... do you need it?
May be better use usual web cam?
 
Also admin promised to show new board with USB... waiting Smiley
