Codes for adding letters to 8X5 leds

Codes for Adding letters to 8X5 LEDs

From the last blog we have written codes to On/Off a LED individually. So here I gonna explain how to display letters on leds.
The trick is simple and that is by blinking a LED each time. The speed is so fast that it appears that all LEDs are ON at same time.

I have used the alphabet patterns or you can say fonts as similar to 16x2 LCD display. So letters will be in 7X5 LEDs matrix.

Example:
So you can blink LEDs row wise(rows first) or column wise. here shows how can you blink LEDs one by one.
Code for Writing 'G' is given below:
void Gi()
{
 int a=timel;//duration for which letter will be displayed
 while( a > 0){
 onled(1,2); onled(1,3); onled(1,4);
 onled(2,1); onled(2,5);
 onled(3,1);
 onled(4,1); onled(4,3); onled(4,4); onled(4,5);
 onled(5,1); onled(5,5);
 onled(6,1); onled(6,5);
 onled(7,2); onled(7,3); onled(7,4); onled(7,5);
 a--;
}}
This code can be used in the last blog I posted using as a function.
