requirement for calculus

It would be very good if i was able to write input parameters to the serial, which are read by an external program on a computer which performs an integration/differentiation operation the output of which is read by the original MC sketch that sent the initial parameter values, for a subsequent step.

Has anyone ever encountered a need for this? I'm quite sure i can make a maplet using maple and build an interface for sending it parameters via a VB form interface but im just having trouble with things because i am self taught hence i rely on you guys.

This has nothing much to do with calculus. It's just a communication issue.

Your arduino can send data to the computer through the com port it's attached to and the computer can send data back to it by the same means.

Serial.print() or Serial.println().

which are read by an external program on a computer which performs an integration/differentiation operation the output of which is read by the original MC sketch that sent the initial parameter values, for a subsequent step.

Serial.available(), Serial.read(), atoi() and atof().

What would you get if you used walnut or cherry?

haha you are so funny Paul you can tease all you want but they taught me to use maple in uni for the first 3 yrs so yep i use it as much as possible.

why isnt atoi() & atof() in arduino ref or again make fun if i havent seen it

I just finished turning a 20" bowl from a maple burl. So, seeing maple just made me need to yank your chain a little.

There is a lot of stuff that isn't in the Arduino reference documentation, because it is not Arduino-specific. sprintf(), strcmp(), atoi(), atof(), memset(), memcmp(), sscanf() just to name a few commonly used C functions that are not documented there.

...and they are documented here: avr-libc: Related Pages

The AVR libc manual is specific to the AVR version of libc and you will find more general guides and tutorials to using the C library elsewhere.
