By downloading the free Eclipse (AVR32 Studio) + gcc you will get access to the Software Framework which includes OTG host drivers/FAT file systems allowing you to access the USB memory. You can use a Wizard to create a large part of your project. -- Best Regards Ulf Samuelsson These are my own personal opinions, which may or may not be shared by my employer Atmel Nordic AB

We were planning on using one - now the design must be changed to use some sort of ARM. The AP700x was suddenly dropped to "not recommended for new designs" and has all but disappeared from their website - even our distributors were caught by surprise.

What I do know is that the flash based AVR32 has been a huge success in the mobile phone and automotive market, When you have a bunch of customers committing to multi-million purchase, that tends to influence decisions. I would not be surprised if someone made a decision based on ROI (Return On Investnent). - Anyone remember the financial crisis? - Money for the development grows tight! Partly it is my fault!. When decisions on investment was done the top priority was given to the UC3C, which is my little baby. This is going to be one cool device. Talked to a Cortex-M3 customer - in one of our largest companies, just returning from Embedded World, and when I described the internals of that device, he commented: "I have seen your competition in Nurnberg, and they take the CM3 and put peripherals around, this however is a motor control system" http://www.atmel.com/dyn/corporate/view_detail.asp?ref=&FileName=32bitucfloating.htm&SEC_NAME=Product > I'd like to know that too.

I have a later version of the chip running linux on my desk. -- Best Regards Ulf Samuelsson These are my own personal opinions, which may or may not be shared by my employer Atmel Nordic AB

Regards, RK sure used Google, I'd like a rabbit on the processor with which it is easier to use usb |
