Hi Bernhard

You can try to add this chip to SIMpad.
The interface is on the PCMCIA bus, so you do not need to solder
the wires to the CPU directly. You can use the pins of the PCMCIA
drivers. I cannot give you the schematics of the board but I can
help you to find the correct pins.
The USB host requires considerable power. Driving a USB memory stick
is no problem but other devices will empty the battery quickly...
Try to find someone with electrical engineering background to avoid
wrecking your SIMpad.

Regards
Walter

Betreff: Simens SIMpad - adding USB Host Controller ISP1160 aka LQFP-64 

Dear Mr. Schweizer,
my name is Bernhard Guillon. Guylhem Aznar, who you helped by his MMC 
mod, gave me your email adress. I hope that this is ok for you.
I want to add a USB Host Controller ISP1160 aka LQFP-64 to the SIMpad 
SL4. Unfortunate I am not an electrical engenier. I think your time is 
short so I don't want to disturb you. But if you have some time I would 
be verry lucky for some help.
I have a connecting shematic (AN10025_1.pdf wich I added as attachment. 
My main problem is that I don't know if it is a clever idea  to just 
solder some wires on the named cpu pinns. I think I will destroy my 
SIMpad by doing this. Are the Mainboard shematics available for free? 
Could you say me where I have to solder the wires? Many many thanks forward!

If you have any technical information which you could give me for adding 
it to opensimpad.org - I would be verry happy, too.

regards
Bernhard Guillon

Hi Bernhard

Sorry for the late answer. I was away.

You can add USB in parallel. You need the pins that go to PCMCIA.
You connect them before the buffer though.
Then the chip select will define where the USB chip resides in the
processor's address range.

Walter

Hello,

I want to thank you for your efforts!
Now I asked me if it is possible to add it parallel to the PCMCIA 
adapter, so the adapter is free for a WLAN card? Or is ist better to 
connect a CF adapter to the USB host, so the resulting card will fit in 
the PCMCIA slot and give a CF slot + USB instad of only PCMCIA or USB.

Bernhard
