Hello...
May I ask for help with my project, we been doing a 12x8 DIY LED Matrix displaying text from A to Z that didn't scroll form left to right and without the use of any shift registers.
*Arduino Pin Connection:
Digital Pins:
0 to 7 - Row 1 to 8 (LED Cathode)
8 to 13 - Column 1 to 6 (LED Anode)
Analog Pins:
A5 to A0 - Column 7 to 12 (LED Anode)
Schematic Diagram:
Here is my code:
const byte letters[] = {{252,18,17,17,18,252},//A
{255,137,137,137,137,118},//B
{126,129,129,129,129,66},//C
{255,129,129,129,129,126},//D
{255,137,137,137,129,129},//E
{255,9,9,9,1,1},//F
{126,129,129,145,145,114},//G
{255,8,8,8,8,255},//H
{0,129,129,255,129,129},//I
{96,128,129,129,129,127},//J
{255,8,24,36,66,129},//K
{255,128,128,128,128,128},//L
{0,255,2,4,2,255},//M
{255,4,8,16,32,255},//N
{126,129,129,129,129,126},//O
{255,17,17,17,17,14},//P
{126,129,129,161,65,190},//Q
{255,17,17,17,17,238},//R
{70,137,137,137,137,114},//S
{0,1,1,255,1,1},//T
{127,128,128,128,128,127},//U
{0,63,64,128,64,63},//V
{0,255,64,32,64,255},//W
{0,227,20,8,20,227},//X
{0,7,8,240,8,7},//Y
{193,161,145,137,133,131};//Z
void setup() {
DDRD = B11111111;
DDRB = B111111;
DDRC = B111111;
}
void loop() {
}
I have a problem in displaying it to my DIY 12x8 LED Matrix.
Thanks for your help.
