AVR as usb host?

Post by seb » Tue Jul 29, 2008 8:04 am

Hi, im fairly inexperienced with usb itself, I believe that in principal it works similarly to i2c, but I know there are differences in how it actually works. However, I do know a bit about electronics, and looking at the sample schematics included with avrusb, it appears that the avr device is always connected as a slave...?

Is it possible to use the avr as the host, and read from usb keys etc? Because that would greatly aid me with my current project... I have been trawling the internet, and am yet to find a way to read from a usb storage device...

Thanks,
Seb

See "embedded USB hosts" at http://www.obdev.at/products/avrusb/links.html. The first link is a firmware implementation.

@christian: thank you very much! I'm going to try this when I get the hardware. My next problem will be actually reading from the usb key... don't think it should be too much of a problem though...
Thanks again
