Hi Tom,

Thanks very much for your response and sharing your experience with the
ICD2. As Charles told me, MPLAB's help details the resources used for
different microcontrollers.

For the benefit to others who are interested (cut and pasted from the
Microchip MPLAB help):

PIC18F452 ICD resources used

 Program memory used: 0x7DC0-0x7FFF

 Data memory used:  0x5F4 - 0x5FF
                    0xFD4*
                    0xFB5 - 0xFB9*


* On several devices, these locations correspond to SFRs. As such, locations
FB5-FB9 are only "semi-reserved".  This means that you can actually use the
registers in your application software.  However, you cannot access these
registers from the file register, SFR, or watch windows in MPLAB IDE.  If
your application and debugging depend upon these registers, you are
encouraged to copy these registers to non-reserved locations before breaking
to view the values in these registers.




Thanks again Tom for your help and time.

Best regards,

Ken Pergola

I have one and am happy with it. I wanted to get up to speed quickly with
the '452 so I bought the package deal that has the ICD2 and the PICDEM2
PLUS board.  These are probably the best development tools I have ever
purchased.  And this week, I downloaded the M'chip C18 c compiler to learn
c programming.  For me, this tool suite is a good combination.

I think there is only one version and it has USB and RS232 both.  People
*have* said on this list that they were getting "the usb version", etc. but
afaik, there's only one version.

My ICD2 always reported that it failed it's self test yet it appeared to
function correctly. M'chip tech support just advised me to download MPLAB
6.3 which has new firmware for the ICD2.  I did and it fixed the selftest
failure reporting.  Unfortunately, it also made it take about 3 times
longer to program '452 chips.  Now it's around 30 or 40 seconds; it used to
be about 10 to 15 seconds.  Not a big deal but seemingly a small step
backwards.

One other good thing, at least for me is that the ICD2 is fairly small and
easy to transport from home to work to home, etc.

Good luck!
Tom
