Lpc2000

Hello,

 

I have been using 8-bit AVR MCU's so far (ATMega8) for relatively small
projects. Right now I need to convert a PC application running under DOS to
an embedded platform. The LPC2xxx series is one of the possible targets I
will be using. I would prefer a single chip solution without external memory
interface.

 

I am wondering how memory hungry 32-bit C compilers (GNU, Imagecraft ICCARM)
are?

 

Has anyone had any experience porting an application from an 8-bit to a
32-bit platform? What were the ratio's of RAM and FLASH usage?

 

I have been told before by several people that 32K RAM memory on a 32-bit
platform is not much and to be considered a minimum.

 

I will be using no OS or perhaps a small RTOS (FreeRTOS, Nut OS) which will
not need a lot of memory.

 

Kind regards,
