Bob,

I never used ARM7 I am sure it is as good as pic some
times even better then pic but the main question 
is how do you know ARM7 is better then PIC18?
here is why I stopped using assembly

1. takes long time 
2. each company has their own assembly forever I have to learn assembly
3. updating, changing the chip effects other subroutines timing etc.
4. lots of things needs to remember "errata sheets etc"
5. others do it in C and get it done much faster then the assembly guy.
6. it is good to know assembly and is good for small projects.
7. program memory is cheap so optimization is not important
8. by the way it is good to mix asm with c like "sleep" "nop" etc.

Subject: [PIC] ARM7..should I take the plunge?


I have several 18F projects under my belt now, all of them written in
assembler.  Life has been good going this route thus far but I have a new
long-term project I am going to be starting on soon and I have been doing
some light reading of the tutorials on ARM7 development over at sparkfun.com.
Once upon a time I purchased a copy of CCS PCWH to do my coding in C and
found that I had less trouble and tighter code writing in assembler, and I'm
sure it would be no different on the ARM7.  I'm afraid the new project might
get too cumbersome to do in assembler.  I'm curious to hear about the
experiences of those here who have migrated their designs to the ARM7 and
what are the pitfalls of using the LPCxxxx devices from NXP...  Not much has
been posted here about the PIC24's so I am curious to hear some opinions on
the advantages/disadvantages/trade offs/comparisons of the ARM7's and the
new PIC24's.  If I do go down the ARM7 path I would like to stick with GCC
and the free tools available, and not spend thousands on compilers.  One
thing I do know that I will miss is the simulator.  Anyhow...it seems that
the ARM chips are getting to be popular.

Regards,
Bob
