Lpc2000

I've been using the SeeHau (Nohau) system, and I find it quite good.
When debugging, and you do things with breakpoints etc. it _very_
intensively
provides comprehensive feedback on various issues, that really cuts down
the time getting familiar with it, but of course is of less importence once
you're
proficient with it.
Note that it comes bundled with the full uC/OS by Jean Labrosse, ported for
LPC2100, and that SeeHau is fully Kernel aware, able to display status of
the RTOS,
TID/TCB of tasks and their state, events, semaphores, maibox traffic, what's
where etc.
so you can also even single step the app with interrupts running in the
background.
(A bit harder at times of course)

The Nohau system uses the HI-Tech C compiler toolchain.
The issue mentioned not too long ago about HITide being slow maybe
should be clarified better :
The "slow" was actually referring to the MSP430 simulator, and JTAG.
I find it builds more than fast enough, even on my AMD750 w/ 512 Mb RAM.

I personally have little reservation in that regard.
The introduction of XA read in the databook :" 7 derivates / year" (1997)
It's 7 years later and there's bugger-all around.
But I agree too that being an ARM core, and having such a small package
despite MCU perfromance


Regarding the breakpoints w/ Flash on JTAG (gdb issue)

SeeHau supports 2 breakpoints in Flash, and to single step you need to run
from RAM.
I don't know where that will go.


We're certainly committing to LPC2100. I have been in the process of probing
my spectrum
analyzer on it to see how it behaves EMC wise. very important for me becuase
we want to use
it in RFBasic.
