I will work with a 18F4520 in a near future, I've read some datasheets =

regarding the USB connection.

Just as an advice, If i understand weel,  you are trying to do a 1M =

sample A/D conversion? If you are thinking in using the internal A/D =

module, as far as I know this is impossible with the pic you have, the =

A/D is simply not that fast.

Also a 1M samples at 10bits, will mean at the best 10Mbps usb =

transmission.  For that, as Microchip says, you should design your own =

USB driver.


Best Regards
