I think there is a paperclip reset hole on the side of the pixhawk.  That should do it.

Good evening 

Is there a simple way to reset my pixhalk ? 

I purchased one to put in my 650 tarot and used mission planner to set it up, as I am use to this.

Then I read Qground control was better , don't believe everything you read.

So tryed it and don't like it and thought I could just reinstalled program from mission planner.No you can't won't install firmware ,so I want to start all over again from fresh. Is there a way to do this ? Looked and asked intranet without any joy.

Anybody?

Regards Dave

Make a cable as Tony describe, I removed the little pins from the connector and change their place

How do you do!

Comment by Cala on May 29, 2016 at 3:41pm

Yes, that the correct position, mine is working now like that. Another thing that don't sound right is a red wire in SCL and a black one in vcc.

The connection cable provided with the GPS is straight, no cross-over of TX/RX (just the whole connector is up/down), but as the motherboard of the GPS (I opened it) is not labelled we don't know that the RX goes to RX as Cala suggests. The only documentation is on the PixFalcon side, so the GPS obviously has TX and RX pins the other way around as Craig says, else it wouldn't work. Both of you are right, no mistake has been made by the Holybro manufacturer besides not documenting the PixFalcon peripherals (shame because the rest of the docs and web site are nice and clean).

On the GPS side we have then, from left to right: 

1 = GND (pin 6 on FC)

2 = TX (RX on FC)

3 = RX (TX on FC)

4 = VCC +5V

5 = SDA

6 = SCL (red, pin 1 on FC)

Sound right?

Yes, but labels were reverse in pixfalcon vs gps, rx with Rx and Tx with Tx, the easier way is if this guys stamped the board as many do, they have lot of space. 

Comment by Craig on May 29, 2016 at 1:55pm

TX and RX are always reversed. TX goes to RX and RX goes to TX. That's how serial devices communicate.
