After reading some topics about this and reading new code, I created some pattern of blinking leds.

I also modified a little code of leds.pde, so it easy to extent and add more. Now it can blink depending on fly mode.

I write code of showing leds as:

static void control_leds(byte ledbits) {
    digitalWrite(COPTER_LED_1, bitRead(ledbits, 0));
    digitalWrite(COPTER_LED_2, bitRead(ledbits, 1));
    digitalWrite(COPTER_LED_3, bitRead(ledbits, 2));
    digitalWrite(COPTER_LED_4, bitRead(ledbits, 3));
    digitalWrite(COPTER_LED_5, bitRead(ledbits, 4));
    digitalWrite(COPTER_LED_6, bitRead(ledbits, 5));
    digitalWrite(COPTER_LED_7, bitRead(ledbits, 6));
    digitalWrite(COPTER_LED_8, bitRead(ledbits, 7));
}

So we can turn on/off just by using bits as B10101010 to turn off 1, 3, 5, 7 and on 2, 4, 6, 8.

My patterns for 4 modes:

//stablize mode

//circle mode

//loiter mode

and //Althold mode

Function to control blinking leds is

static void show_leds(void) {
    switch(control_mode)
    {
      case STABILIZE:
          leds_on_mode_1();
          break;
 
      case ALT_HOLD:
          leds_on_mode_4();
          break;
 
      case AUTO:
          break;
 
      case CIRCLE:
          leds_on_mode_2();
          break;
 
      case LOITER:
          leds_on_mode_3();
          break;
 
      case POSITION:
          break;
 
      case GUIDED:
          break;
 
      case LAND:
          break;
 
      case RTL:
          break;
    }
}

And to make it works, just comments the line of code copter_leds_on and add new function to control it in static void update_copter_leds(void)

...

            } else if ( !bitRead(g.copter_leds_mode, 5 ) ) {
                //copter_leds_on();                                                                       //if motors are armed, battery level OK, all motor leds ON
                show_leds();

...

Hope this can be helpful and enjoy with it.

I am having only a problem with controlling the leds.

When I turn led 2, and off others, the led 1 also on. Do not know why, test with ULN2803 only with 5v in, it works and with board only, it also worked well.

Anyone has this problem?

Thanks,

Duy
