Hello everyone!
I have 5 pieces of 5x8 LED matrices. The configuration is shown below. I`ve tried many times in the past to make a panel (scrolling text) with these pieces, but no success.
-
Is there a way to drive all these directly?
-
I have found another method (maybe I can adapt it to what I have) that allows me to use less wires.
Can this schematic (sorry for screenshot) be adapted to extend it for 2 matrices and so on?
And the code, maybe it is helpful:
#define DATA 2
#define SHIFT 3
#define STORE 4
void store();
int pic[] = {0,36,36,36,0,66,60,0};
void setup() {
pinMode(DATA, OUTPUT);
pinMode(SHIFT, OUTPUT);
pinMode(STORE, OUTPUT);
}
void loop() {
for (int i=0; i<8; i++) {
shiftOut(DATA, SHIFT, LSBFIRST, ~pic[i]);
shiftOut(DATA, SHIFT, LSBFIRST, 128 >> i);
store();
}
}
void store() {
digitalWrite(STORE, HIGH);
delayMicroseconds(10);
digitalWrite(STORE, LOW);
delayMicroseconds(10);
}
