Hi all,
I look to write to some USB key from a MCU ('53 or others) Have you some idea to it ??
Manyy thanky thanks
"USB key" is an ambiguous word. Is it a USB memory - mass-storage class, or smart card - CCID, or U3 smart drive, or any other class?
Read out the descriptors of the device using USBView and confirm the class implemented on it.
USBView on FTDI site www.ftdichip.com/.../usbview.zip
"USB Class Codes" on USB-IF www.usb.org/.../defined_class
When it is a mass-storage, these ready-made host controllers are the easy way.
