Hello!
I search whole Internet and not found any examples how to do scroll message with ledcontrol. I try it myself, and have some problems.
My code:
#include "LedControl.h"
LedControl lc=LedControl(12,11,10,1);
void setup() {
lc.shutdown(0,false);
lc.setIntensity(0,1);
lc.clearDisplay(0);
}
const byte a[6]={B01111110,B10001000,B10001000,B10001000,B01111110,B00000000};
const byte r[6]={B00111110,B00010000,B00100000,B00100000,B00010000,B00000000};
const byte d[6]={B00011100,B00100010,B00100010,B00010010,B11111110,B00000000};
const byte u[6]={B00111100,B00000010,B00000010,B00000100,B00111110,B00000000};
const byte i[6]={B00000000,B00100010,B10111110,B00000010,B00000000,B00000000};
const byte n[6]={B00111110,B00010000,B00100000,B00100000,B00011110,B00000000};
const byte o[6]={B00011100,B00100010,B00100010,B00100010,B00011100,B00000000};
void display(const byte letter[6]) {
int i,j,k = 0;
for (i=8; i>=0; i--) {
for (j=0; j<6; j++) {
lc.setRow(0,j+i,letter[j]);
}
delay(150);
}
}
void scroll(char * s) {
int var=0;
while (s[var]) {
if (s[var]=='A')
display(a);
if (s[var]=='R')
display(r);
if (s[var]=='D')
display(d);
if (s[var]=='U')
display(u);
if (s[var]=='I')
display(i);
if (s[var]=='N')
display(n);
if (s[var]=='O')
display(o);
var++;
}
}
void loop() {
scroll("ARDUINO");
}
and effect:
I would get a better result, like
but no idea how to that.
