I was just wondering if anyone has been able to attach external variable space for the robot successfully, or even tried for that matter, if so how did you connect it, and what type of system did you use? Another PIC?
What are you doing that requires it? If you really are running out of memory, the best solution is probably to use another PIC that performs a memory/processor intensive task and reports the result back the the main processor. Often times though, you are approaching the problem incorrectly if you find yourself running out of memory.
