As above picture shows, to display number “0”, the codes in the columns are 00H, 00H, 3EH, 41H,
41H, 3EH, 00H, 00H; send these codes to corresponding columns and you will see the display of
number “0”.
Sample program for displaying “0”
//////////////////////////////////////////////////////////
// set an array to store character of “0”
unsigned char Text[]={0x00,0x1c,0x22,0x22,0x22,0x22,0x22,0x1c};
void Draw_point(unsigned char x,unsigned char y)// point drawing function
{
clear_();
digitalWrite(x+2, HIGH);
digitalWrite(y+10, LOW);
delay(1);
}
void show_num(void)// display function, call point drawing function
{
unsigned char i,j,data;
for(i=0;i<8;i++)
{
data=Text[i];
for(j=0;j<8;j++)
{
if(data & 0x01)Draw_point(j,i);
data>>=1;
}
}
}
void setup(){
int i = 0 ;
