declaring several arrays (LUTs)

Using Arduino Programming Questions
#1

Im highly confused with this... and feel like its a silly question, tbh.
Isnt there a way of declaring several arrays of same length in just one line ?
In the style of

uint16_t ii, iii, iiii, iv;

As you can probably guess, they are-to-be LUTs

What im trying to short down is something like this :

uint16_t sin_data[WAVE_SAMPLES];
uint16_t cos_data[WAVE_SAMPLES];
uint16_t saw_data[WAVE_SAMPLES];
uint16_t tri_data[WAVE_SAMPLES];
uint16_t sq_data [WAVE_SAMPLES];

where WAVE_SAMPLES is already defined in

#define WAVE_SAMPLES 512.

Thanks in advance

Before you go any further could you please say which Arduino you have as your proposed arrays are chewing up an awful lot of memory.

#3

There is, but why would it matter?

#4

Arduino Due ( Code its working, nuh worries there).
Im getting engulfed in more and more lines of code .
Answer, anyone ?

#5 
uint16_t sin_data[WAVE_SAMPLES],
 cos_data[WAVE_SAMPLES],
 saw_data[WAVE_SAMPLES],
 tri_data[WAVE_SAMPLES],
 sq_data [WAVE_SAMPLES];

(It's conceptual - imagine one stupidly long single line)

Defeats the initial purpose :slight_smile:
It was something that has baffled me. My intention is just to write better code, while readable.
Of course code obfuscating is an art in itself 8)

#7

Make a typedef then.
I can't really see the problem.

#8

No problem.
I meant initial purpose of a "one line solution".
Your way is a new way for me and ill use it
Thanks !

#9

If your arrays are the same length, as AWOL pointed out, a typedef would be useful.

typedef uint16_t arr_t[ WAVE_SAMPLES ];

arr_t ii, iii, iiii, iv;

Thanks .
