Which microcontroller to use?

[rckr]

Hi,

I have been working with Arduino UNO for my projects , it worked fine for me.But my next project requires more RAM (atleast 1 MB) as it has more data usage . UNO or other arduino wont work as it as less SRAM . Can you please suggest me other microcontrollers which have a easy to use library as arduino provides ?

What are you doing that requires 1MB of RAM? Perhaps you need to use a PC instead.

If uC in your project is connected to PC, you can use fast USB transfer (1 MB/s) for exchange data with PC, without storing on uC. If in your project uC is used as stand alone, than (if it is fast enough) you can use SD card for data storing. If SD is too slow, than you can use DRAM (because 1MB SRAM is too expensive) and some uC (ARM) that have DRAM interface without glue logic.

Hi,

You say the extra ram is needed for DATA storage rather than program code, so why not use cheap EEprom chips which can be used on the SPI or I2c lines.


Doubt you will find any micro with such extensive free libraries as the Arduino.
