Re: LPC2148 USB

2006-02-09 by Danish Ali

You are right, the LPC2148 CANNOT act as a host - you cannot
plug a pen drive into it.

But that's not the question that was asked. ;-)

What was asked was can the LPC2148 connect to a PC over USB
so the PC would be the host.

Sorry if that's something I didn't make clear. I tried to extend
my answer into one of the questions that wasn't asked.

Regards,
Danish
