Lpc2000

Dear nonuckingfumber,

OT: would it be possible to change your name into your real name, my
e-mail mind keeps thinking this is spam ...

Note that the lpc2148 is the only device with the DMA buffer, other
menbers of the lpc214x group do not have this function.

The ftdi solution will cost you something of 10-12 pins to interface to
the lpc210x if you take an ftd245 or a similar parallel interface. Using
an ft232 like device with a serial interface may not give you any
(technical) advantage on top of a standard UART connection...

The gotchas on the lpc2148 are still there. Look at the recent USB posts
in this group, it looks like USB is not fully stable and defenitely not
working on GCC (at least not publicly availale that is).

The qestion if you should go for ftdi or lpc2148 is not that easy to
answer. If you want a standard mass storage or HID device I would go for
lpc2148, if you do handle every driver detail in a specific
(windows/linux) application I would currently still select the ftdi -
shorter time-to-market.

USB driver development in both Linux and Windows is not an easy thing -
although it's easier in Linux than in Windows (but what is not ...)
