From: Stefano on 9 Mar 2010 10:36 I have to develop an application, as well as management of certain I / O I must read data from USB key external (USB host). Wkich microcontroller easily allows this feature? As possible solutions to simplify the function are possible? Councils also on development tools at low cost. Cortex M3 ? Freescale ColdFire ? Thanks

A USB port is not just a serial port, its an entire protocol, with license issues to resolve as well. When you say, "USB KEY" do you mean a USB flash drive or a USB security device? hamilto

The AVR AT90USB series has a couple of chips that do OTG, Microchip has a PIC32 OTG. Google for USB OTG. Pick one that the vendor supplies the software stack. -- Joe Chisolm Marble Falls, Tx.

Look at the site: http://www.vinculum.com/ and more specific the Vinculum VNC1L USB Host Controller. They have a demo set VDIP1 you can play with. Bu |
