View Full Version : From Basic stamp II to 2e, no memory free change?

07-29-2008, 09:24 PM
Because I need more memory space for my programs, I bought the Basic stamp 2e to replace the Basic stamp II. I was especting to see more free space in the Memory Map of the Basic Stamp Editor, but I am seeing the same Free %... even though I have already change the directive to {$STAMP BS2e}... Why is that? Does the 2e have more memory for programs?
Thanks 4 any advice.

The 2e has more memory "slots" of EEPROM that you can use with the "RUN" keyword.\

So you need to use "multi-slot" programming to use the additional memory.

Thanks for your answer! I am now wondering how can I send a program from the Editor to a specific slot and also if there is a way to see the memory map of a specific slot.

Thanks in advance

Thanks for your info Stephanie, I have read the articles but have some doubts about it. There is any way to send a program to a particular slot? Or the only way is sending the whole project group using the {$STAMP BS2e,file1,file2,...,file7} way?

Thanks in advance/

Once the multi-slot program is loaded in the stamp, the editor will only download to any slot that has changed from the original.
