Is this the way MChip should be going with the ICD system ??

They are nice. Even the better Serial based or USB based debugger are not
expensive. Silabs parts are of good features and the debugger/programmers
are cheap and good. The professional C compiler from Keil is very expensive
though.

The main problem with Silabs seems to be the weak EMC performance.
In my previous job, we switched to Silabs parts for three projects and
encountered many problems with CE test. Now they decide to stick to
Microchip.

The other problem is that the price of Silabs MCUs is on the expensive
side.

Hello Alan,

I think Microchip has it already in PICKit 2 Express.  You may say
that they are different, in size, in style, in price... but I deem
them are in same class.


Best regards,

The picKit2 is pretty close to that, isn't it?

I'm happy to see Si-labs improve on their original "toolstick eval
kit."  I think this was the first device of this sort, but it was
an annoyingly crippled thing.  I think the TI EZ-MSP430 demonstrated
a better way, and Silab's new stuff is following...

As of the current MPLAB integration, PICkit 2 is really very far
away from being a full-blown debugger. It has the potential. The
debugging right now is also pretty slow (tested under MPLAB 7.42
with the 44pin 16F917 demo board.

The TI chips are nice. The development tools are nice as well. The
full-blown USB and Parallel JTAG debugger is also quite cheap. Actually
we just got a new USB JTAG debugger free from TI. I have tested the parallel
port based debugger and they are quite easy to use and the speed
is quite okay. It is said that the parallel based debugger is well supported
under Linux with mspgcc.

However, they have rather limited peripheral mix. The higher-end MSP430s
are not cheap at all.

I've also tested the USB based JTag debugger with TI TMS470 demo boards.
The JTAG debugger works much better than ICD2. ICD2 is oay with PIC16F
and maybe PIC18F. But it was really very slow when debugging the Explorer 16
demo boards with dsPIC33F/PIC24 last time I tried it.

All in all, I think Microchip has the best chip mix. However, PICKit 2 and
ICD2 has a long way to go to be comparable with the JTAG debugger/programmer
for Silicon Lab C8051F, TI MSP430 and Atmel/Philips/TI ARM7 based MCUs.
REALICE is supposed to be better but it is not in the same price range of
ICD2.

I'm not sure what features you think they should be taking over, but the
one striking difference seems to be size. And IMO small size is not
necessarily a good thing for an evaluation/development system. I want to be
able to easily poke around, and maybe add custom hardware through some
wires. Seems possible, but if it were a bit bigger, it would probably be a
bit easier.

the trouble with the pickit 2 debug express is that (afaict) it only
supports one pic and a 16 series one at that!

also why can't microchip standardise on an ICSP/ICD connector? every
programmer they release seems to use a different one!
