Hello everyone
I try to write an improved audio spectrum analyzer.
In order to display. 32x16. But it does not work. It runs at 16x8. Works by winamp music USB Serial
Help me with.
code
#include <SPI.h>
#include <DMD.h>
//#include <DMD2.h>
#include <TimerOne.h>

#define DISPLAYS_DOWN 1
#define BRIGHTNESS 50
byte count=0;
DMD dmd(DISPLAYS_ACROSS, DISPLAYS_DOWN);
//SoftDMD dmd(1,1); // DMD controls the entire display
int peak_hold_time = 1; // how long before peak decays
int peaksize; // how many individual peak bands we have (dep. binsperband)
int array[16] = {0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0};
