Hello to all,
From now i was devloping application using LPC 2138, it has 32K RAM and 512K Flash. My programe is requiring more SRAM, as I am using 100k Image sensor, it quite more image processing is there.
#1) can I get any flashless mc from LPC track itslef [so i could have minimmum changes in code if changing mc], but with more then 100k of SRAM ??
I have checked paramatric search of keil, i was unable to locate uc more then 64k in Philis LPC track.
#2) Is it possible to interface external SRAM with current LPC 2138 ???
#3) If I plan to go with ATMEL's controller AT91R40008 [or other uc with <100K SRAM and with very less or no flash. HOW MUCH MY CODE OF CURRENT APPLICATION SUPPOSE TO AFFECT??
In my code i have devloped GPIO modules, Camera IC's Drivers, serial interface modules and IAP modules.
Please guide me, it is critical for me
Regards, mittal
thanks for kind advice,
Actually its true that i need to continue to LPC track rather then ATMEL, to avoide overall program architecture and [cost too, as ATMEL is not having general onchip pheripherals also]
As you told also,I am in favor of lpc2214, and then i need to interface external RAm to it. If i use RAM as external to controller, How should my programe can use external address space? Can you suggest from where can i have these informations..
Thanks in advance mittal
