Hello All,
I have an application which I am writiing for the
PIC14 range of processors. I have written the
application in SDCC C. I use the following line:
sdcc -mpic14 -p16f628.c myproc.c
The compiled .asm output seems to be quite bloated and
the .hex file is about 1200 bytes in length.
I have tried to optimize the code as much as possible,
but I can only get this down to 820 bytes.
The code is not that complicated <30loc and just seems
to be a bit big for my application. If I write anymore
code, I will blow the 1K limit on this!
I have asked a friend to try and compile my application
using CCS C compiler and the resultant code is only 175
bytes (optimized version). There seems to be a massive
difference size of the generated outputs.
I have tried the options --opt-code-size and
--opt-code-speed, but this seems to make no difference.
Is there any way I can optimize this to be even smaller?
Is there an FAQ on the subject, in particular using the
PIC range of chips.
Many thanks in advance,
Richard
