Building A Larger Array

Projects Programming

Hi All,

I'm quite new to using Arduino but have found it very useful.

Currently I'm stepping through DMX values using the DMXSimple library but have found the upper size of the array that I can have on my Arduino Uno to be quite small. Are there any suggestions for a better method of doing this, possibly using an SD card to store the array. I'd appreciate any advice including any other references that might be be useful.

Thanks in advance

Jack

An Arduino MEGA has more memory for things like arrays.

If the array is full of constants (values that never change) you could use 'progmem' to keep the array in FLASH memory to save room in SRAM memory.

Usually you can get better help if you post the code you're having problems with.
