Running out RAM - Noob question

[klausnielsen]

Hello everyone - Hello Pieter
I'm learning to use your super cool library. Working on a Nano, I'm running out of RAM in a sketch that uses 8 multiplexers and array for 64 CCPotentiometers. (Will probably have to upgrade to Mega or similar, since the Nano is low on memory.)
I'm trying to use the tips for saving memory, but it doesn't have an effect. Am I missing some additional lines in order for them to work?

#include <Control_Surface.h>

#define IGNORE_SYSEX 0
#define NO_SYSEX_OUTPUT 0
#define CS_TRUE_CONTROL_SURFACE_INSTANCE 1
#define DISABLE_PIPES 0

auto &serial = Serial;

Any comments or help would be super appreciated
Cheers
Klaus

You have to change the values in the Settings.hpp file in your Control Surface installation (inside of the ~/Arduino/libraries folder). Defining those macros inside of the sketch cannot have any effect.

hey - it worked! :) thanks a bunch
and thanks for the quick response

now I might just be able to squeeze the sketch on to a Nano :)
