This is certainly doable.  The issue is getting the USB stack.  The IAR
and Keil samples implement HID and Mass Storage devices, but not a
communications controller. Certainly, the hardware is capable of doing
Serial Emulation.  

 

The other issue is ISP.  If you want to change your code, the two easy
ways are ISP or JTAG.  So you might want to expose either of those
connectors.  On a design I have in process right now, I am bringing out
Serial 0 with RTS to enable ISP for the early versions of the product -
a safety net for field upgradability.

 

The elegant solution that I is in my product spec is to support IAP via
USB to allow the program to be updated.  Ideally, Philips would make a
USB version of the boot loader

Subject: [lpc2000] USB Philosophical Question (slight OT)

 

We'll looking at the Phillips LPC2148 for a rackmount device where we're
considering using USB *instead* of DB9 (9600,N,8,1) for local
configuration and diagnostic support.

Has anyone here considered this type of application for USB?  Any
insight is greatly appreciated.
