a reliable FAT 12,16 and 32 with read and write is a lot of code. I don't what you are talking about but with our optomized code it is about 50K flash and 5K RAM adding on USB is another 50K flash and mass storage class is another 30K!!! Gus --- In AVR-Chat@yahoogroups.com, "Jesp

If you only want to talk to USB-memory sticks, the host implementation part is pretty simple. A lot of the regular chit-chat that set up the USB link can be skipped. I've tried this with a EZ811 chip from Cypress, which is supersimple to interface to the AVR. (sorry, no code is a

There is no plans to sell the source codes yet but you can purchase a library license. Details are on website. We are also going to add interpreter that runs with USB and FAT. This way you can do whatever you want from your own code that runs on USBwiz --- In AVR-Chat@yahoogroups

I suspect you might have set CKSEL to '0000' which selects external clock. Try to use a crystal oscillator or build you own and feed the clock to XTAL1 pin. An alternative is to use a AVR chip with CKOUT like ATmega48/88/168/165. William Lai MCU ProShop http://www.mcuproshop.com

Both constructs are equivalent. One thing you *do* have to pay attention to: Make sure your access is non-interruptable as the temporary register used to hold the high byte can be clobbered by an interrupt handler doing a word access (there is only one temp register...) I must ad
