Hi,

I wonder is it in prinicple not possible to *hack* host functions e.g.
to connect a USB memory stick to the 214x ?

Cheers,

LPC214x is a peripheral and so is the USB memory stick and for that, 
it is impossible to get them to communicate. You need a USB host to 
do so. Check this out as a USB host solution

I know this, but I wonder if I can use it in host mode as well.

>> I wonder is it in prinicple not possible to *hack* host functions

By *hack* I meant something like I can do e.g. to simulate a SPI by going
thru a port directly instead of using the LPC peripheral.

I found another one at Atmel which is even better as you do not need an
USB chip: AT43USB380 (host,device or OTG)

This is not a processor! This is a USB interface chip. How it is 
better? These are totally different products! I think I am missing 
the point. Anyway, USBwiz is completely different as it contains all 
needed unctions to run the USB host + mass storage layer and FAT 
layer.

If by "contains all needed functions" you mean "interfaces with
Philips ISP1160 USB Host to provide high-level driver interface." It
sounds like you're claiming that you sell a one-chip solution based on
the LPC, which is not true.

Agree. Better w.r.t number of chips. USBwiz => 3 chips, 43USB380 => 2 chips

But I like a single chip solution (need not be ARM): MCU with USB host (or 
OTG) + LCD (any tip ???).
I need to attach custom USB device, so USBwiz is no alternative at all.

There are many chips with USB device + LCD, so I just wondered if I
could handle the low-level USB host stuff by hand ( I need 100K/year, so
SW cost does not matter much, but chip costs a lot :-)

On a resent presentation Philips says they will have a uP in the LPC 
series with USB host functionality and OTG on chip (LPC23xx) H1 2006.  
With that volume in mind you may be able to get early enginering samples 
from them.

I have similar requirements for an upcoming product, though much lower
volume. I don't think I've seen a single arm7 with usb host that
actually worked. I've been looking at Atmel's at91rm9200 for my
purposes, which don't require an LCD. They have the at91sam9 that has
similar features and an LCD controller. Also, we've got quotes on the
freescale wireless parts that have been surprisingly low from our
Future rep. Those chips have 3d acceleration even, which we're looking
at for another future product.

Check out the following chip (I don't think this one was mentioned 
before):

AT43USB325E-AC IC USB KEYBOARD CTRLR HUB 64LQFP

You can load your own code in it, it has a built in keyboard 
controller, it has a built in hub (uplink and downlink), and you can 
run an LCD off of it.

I was looking at this last night ... it appears to be for building
a keyboard, not plugging one in. I don't think it's a USB host
controller that you plug USB keyboard into. It appears to be for
building a keyboard with integrated USB hub. Somebody please
correct me if I'm wrong on this.

Again, this is a device not a host. There is no ARM7 chip with 
internal memory and USB HOST, yet! I think cypress have something 
but it is not ARM

I think you are correct, all these AVR based chips look like they support
USB device (or function).

Saw a press-release about it and it looks promissing. Price < 10€ is ok.
A similiar (in functionality) SH3 costs 30USD.

You mean the i.MX family ? Yes looked at them but they seem to be more
expensive.

My dream would be a chip with OTG + LCD + internal flash + interal RAM.
The sam9s come near theis goal as I will (most likely) need only external
Flash.

But no LCD ?!

External LCD controllers (320x240x16bit) are expensive.

I think Doug was right, this is a USB device chip with in-build HID class 
support.

I don't think you're ever going to get a micro with lcd controller,
usb, and enough "internal" ram for the lcd buffer, usb buffers, and
your application, unless it's one of those new-fangled stacked
packages (is anyone actually producing those main-stream yet?).

So, put two processors on the board!  Why does everything have to be in 
one processor?

IIRC, that was one of the primary reasons for CAN.  But even if they 
don't have CAN controllers, then SPI, I2C or just plain serial ports 
tied together would do.  Set up your own messaging protocol and then 
have them chat back / forth with themselves to move data.

You'll decide on some software strategy as to what tasklets get put into 
which processor.  Then decide how closely / loosely connected the 
programs within each processor would be in relation to each other (how 
much data actually needs to be shared).
