No Nav-Lights Double Wink

Recommended Posts

Hello,

Programmed my 12C508A with the Nav-Lights hex and all works correctly...except.

I cannot get the strobe to double wink, single only no matter what I have tried. I reset from + to pin 4 (with 4.7K ), Started with throttle up, throttle down, transmitter on first, receiver on first. The landing lights work correctly without the PIC reverse on. Any Ideas ??

Is it possible to get another strobe output that is offbeat from the first?

Thank you for your help.

Glen

That is odd. Here is a test for you to perform to help me understand what is going on:

1) Unplug Nav-Lights from the Rx.

2) Turn on Tx, then turn on Rx.

3) With the Stick fully up, plug in Navlights. Do you get double or single wink?

4) Unlplug Nav-Lights. Leave everything else as-is.

5) With the Stick fully down, plug in Navlights. Do you get double or single wink?

I do not have any plans to add a second strobe to the PIC. Too many other projects are in the way.

Tried your tests with no change. I timed the strobe at 81 evenly spaced blinks per minute to make sure I wasn't missing anything.

I turned on the transmitter and left it on.

Throttle was low.

Plugged in the receiver and got the single wink.

Throttled up and then down and landing lights came on.

Unplugged the receiver and throttled up.

Plugged the receiver in and got single wink.

Throttled down, up, down and landing lights came on.

I have the PIC and components on a breadboard.

There is nothing plugged into the receiver but a battery (4.8V) and the Nav-Light breadboard (CH3).

No ESC is in the circuit.

No paranormal activity this week.....(just kidding)

Any Ideas ?

No, don't plug-in the receiver; Leave it connected to the battery at all times. The only part that is to be plugged-in is the Navlights (these little details matter in this test). Please repeat the tests and report what you find.

OOOOH, That little detail!

That's it. I was not cycling power to the Nav-Lights, but to the receiver while the Nav-Lights were plugged in.

Thats why your the host and I'm a bug!

I'm blinkin' and winkin' now. (where's nod?)

Thank You for your patience and sharing these projects with us.

OK, if it works with that method then I think I might know what is going on. A more convenient fix might be possible.

What R/C Rx (exact model) are you using?

Do you have more blank PIC's?

This is a leap of faith, but I am assuming your Rx is slow to initialize when it first gets power. So, I have modified the Nav-Lights code to allow for that. The updated hex file is on the project's page.

With this new V1.1 release you should be able to set the double wink with ease (turn on Tx, set stick up or down, then turn on Rx). Please let me know if it solves your problem.

Your leap was not in vain. This seems to have fixed the dilemma.

As a bonus, landing and strobe blink 1.25 Hz if the transmitter is not turned on first.

I am using a Hitec 555 receiver looking for a Hitec transmitter (negitive shift)

I have an Airtronics RD 6000 super transmitting on PPR modulation.

Now, about that following strobe...

Yup, I added that extra bit in this new release. The buzzer will fast-beep too. It acts as a reminder to turn on the Tx.

Thanks for reporting the good news on the updated release.
