RGB LED PIC example

In this example we used an RGB LED breakout board, here is a picture of an Surface mount RGB breakout board which was similar to the one we used, the PIC was a PIC16F877

RGB Module

We will connect the Red, Green and blue connections up to the following port pins C0, C1 and C2

Then we will send the respective pin high (1) and switch the selected colour on.

Code

This was written in mikroC PRO for PIC

Source code

void main()
{
TRISC = 0x00; // Sets all pins in PORTC as output
PORTC = 0xFF;
 
 
while(1)
{
 
PORTC = 0xFF;
delay_ms(500);
PORTC = 0xFE; //red
delay_ms(500);
PORTC = 0xFD; //green
delay_ms(500);
PORTC = 0xFB; //blue
delay_ms(500);
 
}
}
