surajbarkale Posted September 14, 2004 Report Share Posted September 14, 2004 First decide upon the USB microcontroller you r going to use. Atmel, Cypress & Microchip provide them, Phillips provides a USB interface chip & FTDI provides a USB to RS232 bridge. I think the factor of chioce will be cost. Dose anyone knows a low cost usb controller? Quote Link to comment Share on other sites More sharing options...
Kevin Weddle Posted September 14, 2004 Report Share Posted September 14, 2004 What is the protocal of the USB. How does it synchronize and what is the amount of data it can transmit in one synchro. How does it compare to HDLC? I bet it is very similar. Quote Link to comment Share on other sites More sharing options...
surajbarkale Posted September 15, 2004 Report Share Posted September 15, 2004 It's far far away from HDLC (as far as i am anyway ;D) however check this out http://www.beyondlogic.org/usbnutshell/usb1.htmor PDF if you prefer http://www.beyondlogic.org/usbnutshell/usb-in-a-nutshell.pdfI have attached the sameusb-in-a-nutshell.pdf Quote Link to comment Share on other sites More sharing options...
